NAME
XbaeMatrix - The Bellcore Application Environment (BAE) XbaeMatrix wid-
get class.

SYNOPSIS
#include <Xbae/Matrix.h>

DESCRIPTION
XbaeMatrix presents an editable array of string data to the user in a
scrollable grid-like format similar to a spreadsheet. Non editable
pixmaps can also be displayed on the matrix. The rows and columns of
the Matrix may optionally be labeled. Also, a number of fixed leading
or trailing rows or columns may be specified - these behave similarly
to the labels. While XbaeMatrix looks and acts like a grid of XmText
widgets, it actually contains only one XmText. This means that XbaeMa-
trix widgets with hundreds or thousands of rows have much less overhead
than they would if they used an XmText for each cell.

Clicking on a cell with Button1 will edit the cell. While a cell is
being edited, Tab and Shift-Tab will edit the cell to the right or left
respectively. The osfUp and osfDown keys will edit the cell above or
below. Ctrl-Tab and Shift-Ctrl-Tab will traverse out of the Matrix and
into the next or previous tab groups.

The osfCancel key will cancel any edits made to a cell. The osfActi-
vate key will commit any edits made to a cell and store them in the Ma-
trix. When traversing from another tab group into the Matrix, the fo-
cus will go to whichever cell is currently being edited. If no cells
are being edited, then the upper left most visible non-fixed cell will
be edited.

The column sizes may be dynamically resized by pressing the Shift-But-
ton2 combination when over a column boundary, similar to the behaviour
of some popular spreadsheets. After a column has been resized in this
manner, the XbaeMatrix calls the callbacks on the XmNresizeColumnCall-
back callback list for post processing.

If the Matrix is resized until it is too small to display all of the
cells in a given dimension, then it will display a ScrollBar for that
dimension. The horizontal ScrollBar will scroll the cells and column
labels, but not the row labels, fixed columns or trailing fixed
columns. The vertical ScrollBar will scroll the cells and row labels,
but not the column labels, fixed rows or trailing fixed rows.

For the application programmer, XbaeMatrix provides callbacks to assist
in data validation. The callbacks on the XmNmodifyVerifyCallback call-
back list are called before text is inserted into, or deleted from, a
cell. This callback list can be used to force user input to match a
certain pattern (e.g. a date format). Similarly, the XmNvalueChanged-
Callback is called after text is inserted or deleted.

When a cell is edited (by clicking on it or tabbing into it), the XmN-
leaveCellCallback callbacks are called for the previous cell being
edited, if any. The application can verify the data entered in that
cell and disallow editing of the new cell if the data is invalid. If
the data was valid, then the XmNenterCellCallback callbacks for the new
cell are called. These callbacks can be used to specify the editabil-
ity of the new cell.

The XmNtraverseCellCallback callbacks are also called when the user at-
tempts to edit a new cell and when the matrix gains or looses focus.
This allows the application to override the default traversal behavior
of XbaeMatrix.

The XmNdefaultActionCallback is provided to allow a double click action
in a cell to perform some function.

Motif's Drag and Drop functionality can be achieved via the XmNprocess-
DragCallback.

For large amounts of data, the overhead of assigning data to the widget
can be avoided using the XmNdrawCellCallback. This callback also al-
lows user defined pixmaps to be placed in a certain cell. When using
this callback, data for string fields can be written back to the appli-
cation by using the XmNwriteCellCallback.

Classes
XbaeMatrix inherits behavior and resources from the Core, Composite,
Constraint, and XmManager widget classes.
The class pointer is xbaeMatrixWidgetClass.
The class name is XbaeMatrix.

New Resources
The following table lists the new resources defined by XbaeMatrix. The
codes in the ``Access'' column indicate whether the given resource can
be set at creation time (C), or set by using XtSetValues (S), or re-
trieved by using XtGetValues (G).

This resource cannot be specified in a resource file

XmNallowColumnResize
If True, allows the columns to be dynamically resized via the Re-
sizeColumns() action. The default value is to allow column resiz-
ing.

XmNallowRowResize
If True, allows the rows to be dynamically resized via the Resize-
Rows() action. The default value is to allow row resizing.

XmNaltRowCount
Specifies the number of rows to use for each of the XmNevenRow-
Background and XmNoddRowBackround colors. This resource is ignored
if XmNevenRowBackground and XmNoddRowBackround are not used.

XmNboldLabels
Overstrikes the row and column labels to create a bold font ap-
pearance when True.

XmNbuttonLabels
When set to True, the labels will be drawn with a shadow around
them similar to an XmPushButton widget. A ButtonPress event gener-
ated on the labels, when XmNbuttonLabels is True will cause the
label to reverse the shadow and take on a pushed in appearance. A
ButtonRelease event on the same label will invoke callbacks on the
XmNlabelActivateCallback, list. The default value is False.

XmNbuttonLabelBackground
Specifies a Pixel value in which to draw the XmNbuttonLabels.

XmNcalcCursorPosition
If set to True, the insertion position on the text field is calcu-
lated with respect to where the pointer was clicked in the cell.
The default value is False. The insertion position will be over-
ridden if the position member of the XbaeEnterCellCallbackStruct
is set to a valid position.

XmNcellBackgrounds
Points to an array of pointers to rows. Each row is an array of
Pixel values, one for each column in that row. This data structure
is the same as that for XmNcells, except each entry is a Pixel in-
stead of a String. The background of a cell will be drawn in the
color specified for that cell. If XmNcellBackgrounds is NULL,
backgrounds will be drawn using the color specified by XmNback-
ground. This resource is copied. XmNcellBackgrounds may be spec-
ified in a resource file but due to the two dimensional nature of
the XbaeMatrix widget, it must be done by terminating each line
with a \n character. If the XbaeMatrix widget had XmNrows set to
5 and XmNcolumns set to 5, XmNcellBackgrounds would be specified
as:

*mw.cellBackgrounds: blue, white, blue, white, blue\n\
white, blue, white, blue, white\n\
blue, white, blue, white, blue\n\
white, blue, white, blue, white\n\
blue, white, blue, white, blue\n
Care must be taken when specifying these values in a resource
file as an incorrect format can produce undesirable results.

XmNcellHighlightThickness
Specifies the XmNhighlightThickness resource of the XmText cell
edit widget. This resource is also used to compute the size of
each cell. See the description of XmNhighlightThickness in Xm-
Text(3X).

XmNcellMarginHeight
Specifies the XmNmarginHeight resource of the XmText widget. This
resource is also used to compute the size of each cell. See the
description of XmNmarginHeight in XmText(3X).

XmNcellMarginWidth
Specifies the XmNmarginWidth resource of the XmText cell edit wid-
get. This resource is also used to compute the size of each cell.
See the description of XmNmarginWidth in XmText(3X).

XmNcellShadowThickness
Specifies the XmNshadowThickness resource of the XmText cell edit
widget. This resource is also used to compute the size of each
cell. See the description of XmNshadowThickness in XmText(3X).

XmNcellShadowType
Specifies the type of shadow drawn around each cell. Possible
values for this resource are XmSHADOW_OUT, XmSHADOW_IN,
XmSHADOW_ETCHED_OUT, and XmSHADOW_ETCHED_IN. The default shadow
type is XmSHADOW_OUT.

XmNcellShadowTypes
Specifies on a per cell basis, the XmNcellShadowType. Values for
the resource are the same as for XmNcellShadowType. This resource
is copied.

XmNcellUserData
Points to an array of pointers to individual user defined data ar-
eas associated with each cell. The data should be set using Xbae-
MatrixSetCellUserData() and retrieved using XbaeMatrixGetCellUser-
Data(). This resource cannot be specified in a resource file and
is copied.

XmNcells
Points to an array of pointers to rows. Each row is an array of
String, one for each column in that row. For example, the cells
for a 2x3 Matrix could be set up as follows:

String rows[2][3] =
{
"00", "01", "02",
"10", "11", "12"
};
String *cells[2];
cells[0] = &rows[0][0];
cells[1] = &rows[1][0];

Now cells could be used as the XmNcells resource. If XmNcells is
NULL, XbaeMatrix will not generate an internal table of empty
Strings. This implies that if XmNcells is NULL, no cells have been
set. This resource is copied. See the discussion in XmNcellBack-
grounds for how to specify XmNcells in a resource file.

XmNclipWindow
The widget ID of the clip window. The clip window is the widget
that contains the non-fixed region of cells. This resource can not
be set to a new value.

XmNcolors
Points to an array of pointers to rows. Each row is an array of
Pixel values, one for each column in that row. This data structure
is the same as that for XmNcells, except each entry is a Pixel in-
stead of a String. The text in a cell will be drawn in the color
specified for that cell. If XmNcolors is NULL, text will be drawn
using the color specified by XmNforeground. This resource is
copied. See the discussion in XmNcellBackgrounds for how to spec-
ify XmNcolors in a resource file.

XmNcolumnAlignments
Points to an array of alignments (unsigned char), one for each
column. Each element can be one of XmALIGNMENT_BEGINNING, XmA-
LIGNMENT_CENTER or XmALIGNMENT_END. This specifies the alignment
of the text or pixmap in each cell of that column. See the de-
scription of XmNalignment for XmLabel(3X). If XmNcolumnAlignments
is NULL, each column will default to XmALIGNMENT_BEGINNING. This
resource is copied.

XmNcolumnButtonLabels
An array of Booleans that tells the XbaeMatrix which column labels
should be drawn as a button. Each Boolean can be specified as a
Boolean string or integer. In order to use this resource, XmNbut-
tonLabels should be set to False.

XmNcolumnLabelAlignments
Points to an array of alignments (unsigned char), one for each
column label. Each element can be one of XmALIGNMENT_BEGINNING,
XmALIGNMENT_CENTER or XmALIGNMENT_END. This specifies the align-
ment of the text of each column label. See the description of Xm-
Nalignment for XmLabel(3X). If XmNcolumnLabelAlignments is NULL,
each column label will default to XmALIGNMENT_BEGINNING. This re-
source is copied.

XmNcolumnLabelColor
Specifies a Pixel value in which to draw the XmNcolumnLabels.

XmNcolumnLabels
Points to an array of Strings to be drawn above each column. Each
String may have embedded newline characters, in which case the la-
bel will be drawn on multiple lines. If there is a XmNxmColumnLa-
bels defined for this coluumn it will be displayed in place of the
XmNcolumnLabels. If XmNcolumnLabels and XmNxmColumnLabels are
NULL, no labels will be drawn. This resource is copied.

XmNcolumnMaxLengths
Points to an array of int, one for each column. These specify the
maximum length of a String which can be entered in the cells in
that column. See the description of the XmText(3X) XmNmaxLength
resource. If XmNcolumnMaxLengths is NULL or an element of the ar-
ray is equal to 0, then the corresponding width from XmNcolumn-
Widths is used. This resource is copied.

XmNcolumnShadowTypes
Specifies on a per column basis, the XmNcellShadowType. Values
for the resource are the same as for XmNcellShadowType. This re-
source is copied.

XmNcolumnUserData
Points to a user defined data area associated with a particular
column. The data should be set using XbaeMatrixSetColumnUser-
Data() and retrieved using XbaeMatrixGetColumnUserData(). This
resource cannot be specified in a resource file.

XmNcolumnWidthInPixels
Specifies wether the elements of XmNcolumnWidths are measured in
pixels or characters.

XmNcolumnWidths
Points to an array of short, one for each column. These specify
the visible width of the cells in each column. See the description
of the XmText(3X) XmNcolumns resource. This resource is copied.

XmNcolumns
Specifies the total number of columns of cells. XmNcolumns must
be at least one. If the number of columns is changed via XtSetVal-
ues, then XmNcolumnMaxLengths must change or be NULL, XmNcolumnLa-
bels must change or be NULL, XmNcolumnAlignments must change or be
NULL and XmNcolumnLabelAlignments must change or be NULL. The
preferred way to dynamically change the number of columns is to
use XbaeMatrixAddColumns() or XbaeMatrixDeleteColumns().

XmNdefaultActionCallback
Specifies a list of callbacks to be called when a double click oc-
curs in a cell. A pointer to an XbaeMatrixDefaultActionCallback-
Struct is passed to the callbacks. Events are reported to the cell
in which the double click occurs regardless of whether or not a
callback exists. This callback is called by the DefaultAction()
action and is NULL by default. The XmNdefaultActionCallback is
ideal for popping up a dialog or other window when a double click
occurs.

XmNdoubleClickInterval
Specifies the amount of time between mouse clicks before it is
considered a double click. A double click is defined to be the
time between the realease of the mouse button and subsequent press
in the same cell. The default value is inherited from the dis-
play.

XmNdrawCellCallback
Specifies a list of callbacks to be called when a cell needs to be
drawn. A pointer to an XbaeMatrixDrawCellCallbackStruct is passed
to the callbacks. The application can specify what to put in a
cell by modifying the callback struct's data fields. When the ap-
plication callback returns to the widget code, the type field will
determine what the widget draws on the screen. If the value is
XbaeString, then the regular string drawing function for the wid-
get will be called with the value the applicaton assigned to the
string field in the struct. If the value is XbaeStringFree the
widget also calls XtFree on the string when it is not needed any-
more. Else, if the value is XbaePixmap, the widget will do an
XCopyPlane(), in the case of a single plane bitmap, or XCopy-
Area(), in the case of a color pixmap. The width and height of
cell is passed in the struct so the application can know how big
to make the pixmap. In no case will a copy of the string or the
pixmap value be made. The widget also uses the XmNcolumnAlignments
resource to determine the horizontal alignment of the Pixmap. To
have an editable array of data when the XmNdrawCellCallback is
used and the cell is of type XbaeString or XbaeStringFree, use the
XmNwriteCellCallback.

XmNenterCellCallback
Specifies a list of callbacks to be called immediately before a
cell is to be edited. This callback list is called by the Edit-
Cell() action. A pointer to an XbaeMatrixEnterCellCallbackStruct
is passed to the callbacks. The application can specify the ed-
itability of specific cells using this callback list as well as
specifying configuration options for the XmText.

XmNevenRowBackground
Specifies a background cell Pixel value to use on even rows. This
allows the matrix to look like computer paper. For wider bands of
color, increase the size of XmNaltRowCount.

XmNfill
If True, controls whether the matrix should fill all of its avail-
able space when additional space if available, or if it should
simply size itself as large as necessary, regardless of any addi-
tonal available space.

XmNhorzFill
If True, controls whether the matrix should highlight available
space on the right of the selected cell(s) when the selected
cell(s) are in the last column of the matrix.

XmNvertFill
If True, controls whether the matrix should highlight available
space below the selected cell(s) when the selected cell(s) are in
the last row of the Matrix.

XmNfixedColumns
Specifies the number of leading columns (starting from the left
column) which should not be horizontally scrollable. XmNfixed-
Columns must be less than XmNcolumns-XmNtrailingFixedColumns.
Cells in fixed columns are not editable unless XmNtraverseFixed-
Cells is set to True.

XmNfixedRows
Specifies the number of leading rows (starting from the top row)
which should not be vertically scrollable. XmNfixedRows must be
less than XmNrows-XmNtrailingFixedRows. Cells in fixed rows are
not editable unless XmNtraverseFixedCells is set to True.

XmNfontList
If the value of XmNrenderTable is NULL this resource specifies the
font list to be used for the text displayed in the cells and the
XmText cell edit widget. See XmFontListCreate(3X) to create a font
list. This resource is copied. The preferred way of specifying a
font for the table is in a resource file.

When drawing a cell, the matrix uses the first entry with the tag
XmFONTLIST_DEFAULT_TAG if no tag has been set on the cell using
XbaeMatrixSetCellTag. If a tag has been set on the cell the first
entry with a matching tag is used.

XmNgridLineColor
Specifies the color in which the grid line should be drawn if XmN-
gridType is set to XmGRID_CELL_LINE, XmGRID_ROW_LINE or Xm-
GRID_COLUMN_LINE. The default is that of XmNforeground.

XmNgridType
Sets the way the matrix grid is drawn. The grid types available
include XmGRID_NONE, XmGRID_CELL_LINE, XmGRID_CELL_SHADOW, Xm-
GRID_ROW_LINE, XmGRID_ROW_SHADOW, XmGRID_COLUMN_LINE and Xm-
GRID_COLUMN_SHADOW. All of the grid types vary the way the shadow
or line is drawn around the cell. XmGRID_ROW_LINE, Xm-
GRID_ROW_SHADOW, XmGRID_COLUMN_LINE, and XmGRID_COLUMN_SHADOW only
draw a border around the rows and columns, giving a more tabular
rather than spreadsheet appearance. The default is Xm-
GRID_CELL_LINE which draws a solid line around the cells.

XmNhighlightedCells
Points to an array of pointers to rows. Each row is an array of
unsigned char values, one for each column in that row. This data
structure is the same as that for XmNcells, except each entry is
an unsigned char instead of a String. Each entry in the array will
have a value that is either HighlightNone, HighlightCell, High-
lightRow, HighlightColumn, HighlightOther or the bitwise OR of
those values, depending on the value of XmNgridType and which call
was used to highlight the cell. A cell will be drawn as high-
lighted if the corresponding unsigned char does not have the value
HighlightNone. If XmNhighlightedCells is NULL, XbaeMatrix then no
cells have been highlighted. This resource is copied, and cannot
be specified in a resource file.

XmNhorizontalScrollBar
The widget ID of the horizontal XmScrollBar. This resource exists
only for those applications that need to tie another scrollbar to
the matrix's for synchronized scrolling. This resource can not be
set to a new value.

XmNhorizontalScrollBarDisplayPolicy
Determines when to display a horizontal scrollbar in the matrix.
Possible values are XmDISPLAY_NONE, which makes the matrix never
display the scrollbar, XmDISPLAY_AS_NEEDED, which makes the matrix
display the scrollbar when the list is too large, and XmDIS-
PLAY_STATIC, which makes the matrix always display the scrollbar.

XmNlabelFont
If the value of XmNrenderTable is NULL this resource specifies the
font list to be used for the text displayed in row and column la-
bels. If XmNlabelFont is not specified, the value of XmNfontList
is used for the label fonts. See XmFontListCreate(3X) to create a
font list. This resource is copied. The preferred way of specify-
ing a font for the labels is in a resource file.

When drawing a label, the matrix uses the first entry with the tag
XmFONTLIST_DEFAULT_TAG.

XmNlabelActivateCallback
Specifies a list of callbacks to be called after a button label
has been pressed. A pointer to an XbaeMatrixLabelActivateCall-
backStruct is passed to the callbacks on this list.

XmNleaveCellCallback
Specifies a list of callbacks to be called immediately after a
cell has been edited. This callback list is called by the Edit-
Cell() and CommitEdit() actions. A pointer to an XbaeMatrixLeave-
CellCallbackStruct is passed to the callbacks. The application can
perform cell specific data checks using this callback list.

XmNleftColumn
Allows the programmer to specify the first non fixed column to ap-
pear on the leftmost side of the matrix. This resource compli-
ments the XmNtopRow resource. See the discussion of XmNtopRow for
more details.

XmNmodifyVerifyCallback
Specifies a list of callbacks to be called before text is deleted
from or inserted into the XmText cell edit widget. A pointer to an
XbaeMatrixModifyVerifyCallbackStruct is passed to the callbacks.
See the description of the XmText(3X) XmNmodifyVerifyCallback re-
source.

XmNmultiLineCell
is a boolean (default False) which specifies whether the matrix
displays more than one line of text in a cell, when appropriate.

XmNnonFixedDetachedLeft
Indicated that empty space should be displayed after the fixed
rows. This resource only has effect when XmNfill is true and XmN-
fixedRows is greater than zero.

XmNnonFixedDetachedTop
Indicated that empty space should be displayed after the fixed
columns. This resource only has effect when XmNfill is true and
XmNfixedColumns is greater than zero.

XmNoddRowBackground
Specifies a background cell color to use on odd rows. This allows
the matrix to look like computer paper. For wider bands of color,
increase the size of XmNaltRowCount.

XmNprocessDragCallback
Specifies a list of callbacks to be called from the ProcessDrag()
action A pointer to an XbaeMatrixProcessDragCallbackStruct will be
passed to the callbacks. The application can use this callback
list to perform particular processing during a drag.

XmNrenderTable
Specifies the render table used to derive a font set or a font to
draw the text displayed in the cells, the XmText cell edit widget
and the labels.

When drawing a cell, the matrix uses the first entry with the tag
_MOTIF_DEFAULT_LOCALE if no tag has been set on the cell using
XbaeMatrixSetCellTag. If a tag has been set on the cell the first
entry with a matching tag is used.

When drawing a label, the matrix uses the first entry with the tag
"labels". If there is no such entry the first entry with the tag
_MOTIF_DEFAULT_LOCALE is used.

XmNresizeCallback
Specifies a list of callbacks to be called when the matrix is re-
sized.

XmNresizeColumnCallback
Specifies a list of callbacks to be called when a column is dynam-
ically resized by the user.

XmNreverseSelect
Overrides the default XmNselectedForeground and XmNselectedBack-
ground and draws a selected cell in the colours specified by XmN-
cellBackgrounds and XmNcolors for the particular cell. If these
values are not set then the default colours will be used.

XmNrowButtonLabels
An array of Booleans that tells the XbaeMatrix which row labels
should be drawn as a button. Each Boolean can be specified as a
Boolean string or integer. In order to use this resource, XmNbut-
tonLabels should be set to False.

XmNrowLabelAlignment
Specifies the alignment of the row labels. It can be one of XmA-
LIGNMENT_BEGINNING, XmALIGNMENT_CENTER or XmALIGNMENT_END. See
the description of XmNalignment for XmLabel(3X). XmNrowLa-
belAlignment defaults to XmALIGNMENT_END.

XmNrowLabelColor
Specifies a Pixel value in which to draw the XmNrowLabels.

XmNrowLabelWidth
Specifies the width of the row labels. XmNrowLabelWidth defaults
to the width of the longest row label.

XmNrowLabels
Points to an array of Strings to be drawn to the left of each row.
Each String may have embedded newline characters, in which case
the label will be drawn on multiple lines. If there is a XmNxm-
RowLabels defined for this row it will be displayed in place of
the XmNrowLabels. If XmNrowLabels and XmNxmRowLabels are NULL, no
labels will be drawn. This resource is copied.

XmNrowHeightInPixels
Specifies wether the elements of XmNrowHeights are measured in
pixels or lines.

XmNrowHeights
Points to an array of short, one for each row. These specify the
visible height of the cells in each row. This resource is copied.

XmNrowShadowTypes
Specifies on a per row basis, the XmNcellShadowType. Values for
the resource are the same as for XmNcellShadowType. This resource
is copied.

XmNrowUserData
Points to a user defined data area associated with a particular
row. The data should be set using XbaeMatrixSetRowUserData() and
retrieved using XbaeMatrixGetRowUserData(). This resource cannot
be specified in a resource file.

XmNrows
Specifies the total number of rows of cells. XmNrows must be at
least one. If the number of rows is changed via XtSetValues, then
XmNrowLabels must change or be NULL. The preferred way to dynami-
cally change the number of rows is to use XbaeMatrixAddRows() or
XbaeMatrixDeleteRows().

XmNscrollBarPlacement
Determines where the scrollbars will be drawn. See the discussion
of XmNscrollBarPlacement in XmScrolledWindow(3) for a complete
discussion on this resource.

XmNselectCellCallback
Specifies a list of callbacks to be called from the SelectCell()
action. A pointer to an XbaeMatrixSelectCellCallbackStruct will
be passed to the callbacks. The application can use this callback
list to perform selection/deselection of cells using the provided
widget methods.

XmNselectScrollVisible
Specifies whether the matrix will scroll to make the selected cell
visible. This flag is only checked when cells are selected pro-
grammatically, as when the user selects a cell with the mouse, it
will already be visible.

XmNselectedBackground
Allows the background of selected cells in XmNselectedCells to be
specified.

XmNselectedCells
Points to an array of pointers to rows. Each row is an array of
Boolean values, one for each column in that row. This data struc-
ture is the same as that for XmNcells, except each entry is a
Boolean instead of a String. A cell will be drawn as selected if
the corresponding Boolean is True. If XmNselectedCells is NULL,
then no cells have been selected. This resource is copied. It
cannot be specified in a resource file.

XmNselectedForeground
Allows the foreground of selected cells in XmNselectedCells to be
specified.

XmNshadowType
Specifies the type of shadow drawn around the border of the ma-
trix. Possible values for this resource are XmSHADOW_OUT,
XmSHADOW_IN, XmSHADOW_ETCHED_OUT, and XmSHADOW_ETCHED_IN. The de-
fault shadow type is XmSHADOW_OUT.

XmNshowArrows
Specifies whether arrows should be drawn when data in a cell has
been obscured due to the value of XmNcolumnWidths.

XmNspace
Specifies the distance that separates the ScrollBars from the cell
grid. The default value is 4 pixels.

XmNtextBackground
Specifies the background of the XmText cell edit widget. This can
be used to make the XmText stand out against a uniformly colored
matrix.

XmNtextBackgroundIsCell
Specifies if the background of the XmText cell edit widget de-
faults to the core background of the matrix or the background of
the cell being edited when XmNtextBackground has the value XmUN-
SPECIFIED_PIXEL.

XmNtextField
The widget ID of the XmText. This resource cannot be set to a new
value.

XmNtextShadowThickness
Specifies the XmNshadowThickness of the XmText. Interesting ef-
fects can be achieved by setting the XmNcellHighlightThickness to
0 and replacing the highlight with an indented shadow.

XmNtextTranslations
Specifies the XmNtranslations resource of the XmText cell edit
widget. See the description of XmNtranslations in XmText(3X).

XmNtopRow
Specifies the row which should be displayed at the top of the non-
fixed rows. XmNtopRow is specified relative to the first non-
fixed row, so (XmNfixedRows + XmNtopRow) is the actual row number
which will be moved to the top. If (XmNtopRow > (XmNrows - (<num-
ber of rows visible> + XmNfixedRows), then the actual row which
will be moved to the top is (XmNrows - (<number of rows visible> +
XmNfixedRows).

XmNtrackCellCallback
specifies a list of callbacks to be called when the mouse pointer
is being moved.

XmNtrailingAttachedBottom
Indicated that any trailing fixed rows should be attached to the
bottom of the matrix. This resource only has effect when XmNfill
is true and XmNtrailingFixedRows is greater than zero.

XmNtrailingAttachedRight
Indicated that any trailing fixed columns should be attached to
the right of the matrix. This resource only has effect when XmN-
fill is true and XmNtrailingFixedColumns is greater than zero.

XmNtrailingFixedColumns
Specifies the number of trailing columns (starting from the right
column) which should not be horizontally scrollable. XmNtrailing-
FixedColumns must be less than XmNcolumns-XmNfixedColumns. Cells
in trailing fixed columns are not editable unless XmNtraverse-
FixedCells is set to True.

XmNtrailingFixedRows
Specifies the number of trailing rows (starting from the bottom
row) which should not be vertically scrollable. XmNtrailing-
FixedRows must be less than XmNrows-XmNfixedRows. Cells in trail-
ing fixed rows are not editable unless XmNtraverseFixedCells is
set to True.

XmNtraverseCellCallback
Specifies a list of callbacks to be called before a new cell is
edited. These callbacks are called by the EditCell() action and
when XbaeMatrix receives or looses focus. A pointer to an XbaeMa-
trixTraverseCellCallbackStruct is passed to the callbacks. The ap-
plication can specify the next cell which should be edited via
this callback list, thereby performing custom traversal.

XmNtraverseFixedCells
If True, this resource allows fixed cells and columns to be
edited. The default is to not allow fixed rows or columns to be
edited.

XmNuseXbaeInput
This boolean value determines whether to use XbaeInput or Xm-
TextField as the widget used for editing cells. Default is not to
use XbaeInput.

XmNvalueChangedCallback
Specifies a list of callbacks to be called after text is deleted
from or inserted into the XmText cell edit widget. A pointer to an
XbaeMatrixValueChangedCallbackStruct is passed to the callbacks.
See the description of the XmText(3X) XmNvalueChangedCallback re-
source.

XmNverticalScrollBar
The widget ID of the vertical XmScrollBar. This resource exists
only for those applications that need to tie another scrollbar to
the matrix's for synchronized scrolling. This resource can not be
set to a new value.

XmNverticalScrollBarDisplayPolicy
Determines when to display a horizontal scrollbar in the matrix.
Possible values and their effects are listed under XmNhorizon-
talScrollBarDisplayPolicy.

XmNvisibleColumns
Specifies the number of non-fixed columns which should be visible.
The widget will request a size which will allow XmNvisibleColumns
columns to be displayed. The programmer should take into al-
lowance any XmNfixedColumns that are specified. This feature be-
comes even more apparent if the number of XmNfixedColumns changes
at runtime as the value may need to be adjusted to avoid a warn-
ing.

XmNvisibleRows
Specifies the number of rows which should be visible at any one
time. The widget will request a size which will allow XmNvisi-
bleRows rows to be displayed.

XmNwrapType
When XmNmultiLineCell is true this resource specifies how to break
the lines. When set to XbaeWrapNone, lines are broken on newlines
only. When set to XbaeWrapContinuous, long lines are further bro-
ken up so they fit in their cell. When set to XbaeWrapWord the
breaking of long lines occures preferably on spaces.

XmNwriteCellCallback
Specifies a list of callbacks to be called when a cell value
changes and an XmNdrawCellCallback is defined. A pointer to an
XbaeMatrixWriteCellCallbackStruct is passed to the callbacks. The
XmNwriteCellCallback allows data to be written back into the ap-
plication's data structure and must be defined for an editable
XbaeMatrix with an XmNdrawCellCallback.

XmNxmRowLabels
Points to an array of XmStrings to be drawn to the left of each
row. If XmNxmRowLabels is NULL, XmNrowLabels will be used. This
resource is copied.

XmNxmColumnLabels
Points to an array of XmStrings to be drawn above each column. If
XmNxmColumnLabels is NULL, XmNcolumnLabels will be used. This re-
source is copied.

Inherited Resources
The following table lists the resources which XbaeMatrix inherits from
it's superclasses XmManager, Compositeand Core. For a complete de-
scription of each resource, refer to the man page for that superclass.
The codes in the ``Access'' column indicate whether the given resource
can be set at creation time (C), or set by using XtSetValues (S), or
retrieved by using XtGetValues (G).

Callback Information
XbaeMatrixAnyCallbackStruct
A callback struct that is suitable for all callbacks that require
the reason, event, row and column to be available. Any callback
called may therefore cast the third parameter to the following
struct in XbaeMatrix and can rest assured that evrything in it
will be available.

typedef struct
{
XbaeReasonType reason;
int row;
int column;
XEvent *event;
} XbaeMatrixAnyCallbackStruct;

Each of the members are set to the appropriate struct for the
callback.

If this idea is a little foreign to you, recommended reading is
K&R II page 213.

XmNdefaultActionCallback
Callbacks on the XmNdefaultActionCallback list are called when the
DefaultAction() action occurs. The application can bind the De-
faultAction() action to any pointer based event. When a double
click occurs on this pointer event, DefaultAction() will call the
callbacks on the XmNdefaultActionCallback list. A pointer to the
following structure is passed to each callback on the XmNdefault-
ActionCallback list:

typedef struct
{
XbaeReasonType reason;
XEvent *event;
int row;
int column;
} XbaeMatrixDefaultActionCallbackStruct;

reason Set to XbaeDefaultActionReason .

event The event that invoked this callback.

row The row number of the cell in which the double click oc-
curred.

column The column number of the cell in which the double click
occurred.

event

If an application has an XmNdefaultActionCallback, then the call-
backs on the list will be called when the user clicks twice in a
cell within XmNdoubleClickInterval, enabling some action to occur
for the particular cell.

XmNdrawCellCallback
Callbacks on the XmNdrawCellCallback list are called when the wid-
get needs to draw a cell. A pointer to the following structure is
passed to each callback on the XmNdrawCellCallback list:

typedef struct
{
XbaeReasonType reason;
XEvent *event;
int row;
int column;
int width;
int height;
XbaeCellType type;
String string;
Pixmap pixmap;
Pixmap mask;
Pixel foreground;
Pixel background;
int depth;
} XbaeMatrixDrawCellCallbackStruct;

reason Set to XbaeDrawCellReason.

event Always set to NULL

row The row number of the cell that needs to be drawn.

column The column number of the cell that needs to be drawn.

width The width of the cell that needs to be drawn.

height The height of the cell that needs to be drawn.

type The type of ``data'' the programmer wants drawn in the
cell, or which field should be looked at for data to
draw: string or pixmap.

string The string to draw if type is set to XbaeString or
XbaeStringFree.

pixmap The pixmap to copy if type is set to XbaePixmap. It
will be clipped to width by height if necessary.

mask A mask for the pixmap as obtained from the XPM library.
mask is only necessary when pixmap has a depth greater
than one.

foreground
The foreground color of the cell.

background
The background color of the cell.

depth The depth of the pixmap image (in bits per pixel).

If the application adds this callback, when the XbaeMatrix deter-
mines that a cell at (row, column) needs to be redrawn, the normal
cell drawing mechanism will be skipped and this callback called so
the application can tell the widget what to put in the cell.

The type field is defaulted to XbaeString and no cacheing or sav-
ing of the string or pixmap is done.

If the application sets type to XbaePixmap, the width, height and
depth of the returned pixmap will be calculated with a call to
XGetGeometry(). If the programmer wishes to supply the width,
height and depth there is a marked improvement as a round trip to
the X server is avoided. Note that all geometry parameters must
be supplied to ensure successful display of the pixmap.

If a mask is also provided, it will be used to display the pixmap
transparently. Pixmaps drawn in cells also respect the value of
XmNcolumnAlignments.

By defining an XmNdrawCellCallback the need for the storage of the
XbaeMatrix data within the matrix is eliminated and can prove to
be advantageous for memory usage.

To write the data back to the application, use the XmNwriteCell-
Callback described below.

XmNenterCellCallback
Callbacks on the XmNenterCellCallback list are called from the Ed-
itCell() action just before a cell is edited to determine it's ed-
itability. A pointer to the following structure is passed to each
callback on the XmNenterCellCallback list:

typedef struct
{
XbaeReasonType reason;
XEvent *event;
int row;
int column;
int position;
String pattern;
Boolean auto_fill;
Boolean convert_case;
Boolean overwrite_mode;
Boolean select_text;
Boolean map;
Cardinal num_params;
String *params;
Boolean doit;
} XbaeMatrixEnterCellCallbackStruct;

reason Set to XbaeEnterCellReason.

event The event that invoked the callback.

row The row number of the cell about to be edited.

column The column number of the cell about to be edited.

position The location of the cursor in the text field. The de-
fault is to place the cursor at the end of the string in
the cell.

pattern A pattern for the XbaeInput widget (see XbaeInput(3)).
The default is to not specify a pattern.

auto_fill Used in conjunction with the setting of the pattern to
allow literals in the pattern to be automatically in-
serted.

convert_case
If the pattern specifies an upper or lower case letter,
the character typed in the position can automatically be
converted to the appropriate case when set to True. The
default is to not convert the case of the typed letter.

overwrite_mode
Normally, the cursor appears as the familiar I caret.
By setting overwrite_mode to True, the text field will
go into overwrite mode where keystrokes replace the
character underneath the block cursor.

select_text
Indicates whether the text in the cell should be high-
lighted (only valid if doit is set to True also.

map Tells the matrix if the XmText should be mapped onto the
cell. Only makes sense if doit is set to False.

num_params
The number of String parameters passed to the EditCell()
action.

params An array containing the num_params String parameters
passed to the EditCell() action.

doit Indicates whether or not this cell is editable. Setting
doit to False will make this cell not editable. The de-
fault value is True.

If the application determines that the cell at (row, column) is
not editable, it should set the doit flag to False. If the map
flag is also set to False, XbaeMatrix will not place the XmText
cell editor on the cell. If map is left as True, the XmText will
be placed on the cell but the user will not be able to add or
delete characters from it. If the application leaves doit as True,
then the TextField will be editable. In addition, if select_text
is set to True, the text in the cell will be selected via Xm-
TextSetSelection. Assuming XmNpendingDelete for the XmText is
also True, the selected text will be deleted as soon as the next
text insertion occurs.

XmNlabelActivateCallback
Callbacks on the XmNlabelActivateCallback list are called after a
button label has been activated via a mouse click. A pointer to
the following structure is passed to each callback on the XmNla-
belActivateCallback list:

typedef struct
{
XbaeReasonType reason;
XEvent *event;
int row;
int column;
Boolean row_label;
String label;
} XbaeMatrixLabelActivateCallbackStruct;

reason Set to XbaeLabelActivateReason.

event The event that invoked this callback.

row The row number of the button label or -1 if the button
was a column label.

column The column number of the button label or -1 if the but-
ton was a row label.

row_label If the button label that invoked the callback is a row
label, then this value is set to True. If it was a col-
umn label then it is set to False.

label The label on the button that was pressed.

When the XbaeMatrix receives a ButtonRelease event on the same
button label that it received a ButtonPress event, the XmNlabelAc-
tivateCallback is called to allow the programmer to respond to the
event. The callback has been provided to emulate some popular
spreadsheets on the market.

XmNleaveCellCallback
Callbacks on the XmNleaveCellCallback list are called from the Ed-
itCell() and CommitEdit() actions just before the edit to the cur-
rent cell is committed. The application can validate the changes
made to the cell, and allow or disallow them. A pointer to the
following structure is passed to each callback on the XmNleave-
CellCallback list:

typedef struct
{
XbaeReasonType reason;
XEvent *event;
int row, column;
String value;
Boolean doit;
} XbaeMatrixLeaveCellCallbackStruct;

reason Set to XbaeLeaveCellReason.

event The event that invoked this callback.

row The row number of the cell being edited.

column The column number of the cell being edited.

value Contains the new data which will be stored in this cell
if doit is True. The memory pointed to by value may be
modified, or if the new contents are larger than the
current contents, then value should be set to point to a
larger piece of allocated memory.

doit Indicates whether the edits applied to this cell should
actually be stored into XbaeMatrix. Setting doit to
False will cause the changes to be discarded and the
cell will retain its original value. The default value
is True.

If the application determines that the value entered in the cell
at (row, column) is not valid, it should set the doit flag to
False. This will prevent the changes from being stored in the
cell. The TextField edit widget will remain on the current cell.
If the application leaves doit as True, then the changes made to
the cell will be committed and the TextField will move to the next
cell or be unmapped. The application can also modify the String in
value, e.g. to force a String to be all upper case.

XmNmodifyVerifyCallback
Callbacks on the XmNmodifyVerifyCallback list are called while a
cell is being edited. The callbacks are called before text is in-
serted into or deleted from the TextField edit widget. A pointer
to the following structure is passed to each callback on the XmN-
modifyVerifyCallback list:

typedef struct
{
XbaeReasonType reason;
XEvent *event;
int row;
int column;
XmTextVerifyCallbackStruct *verify;
const char *prev_text;
} XbaeMatrixModifyVerifyCallbackStruct;

reason Set to XbaeModifyVerifyReason.

event Always set to NULL.

row The row number of the cell being edited.

column The column number of the cell being edited.

verify The contents of this structure and its use are docu-
mented in the XmText(3X) man page.

prev_text The contents of the cell as seen by this user before the
new text. If other text has already been entered, this
value will not match the official XbaeMatrix value of
the cell. This pointer and the string should not be
modified.

XmNprocessDragCallback
Callbacks on the XmNprocessDragCallback list are called from the
ProcessDrag() action. The application can bind the ProcessDrag()
action to any pointer based event, though by default it is bound
to the Button2Down event. When this event occurs, ProcessDrag()
will call the callbacks on the XmNprocessDragCallback list. A
pointer to the following structure is passed to each callback on
the XmNprocessDragCallback list:

typedef struct
{
XbaeReasonType reason;
XEvent *event;
int row;
int column;
String string;
XbaeCellType type;
Pixmap pixmap;
Pixmap mask;
Cardinal num_params;
String *params;
} XbaeMatrixProcessDragCallbackStruct;

reason Set to XbaeProcessDragReason.

event The XEvent which invoked the ProcessDrag() action.

row The row number of the cell where the drag was initi-
ated..

column The column number of the cell where the drag was initi-
ated..

string The string in the cell where the drag was initiated if
type is XbaeString or XbaeStringFree. This is provided
as a convenience to the application.

type The type of the cell in which the drag was initiated.

pixmap The pixmap in the cell where the drag was initiated if
type is XbaePixmap. This is provided as a convenience
to the application.

mask A mask for the pixmap as obtained from the XPM library.
mask is only necessary when pixmap has a depth greater
than one. Also provided as a convenience to the appli-
cation.

num_params
The number of String parameters passed to the Process-
Drag() action.

params An array containing the num_params String parameters
passed to the ProcessDrag() action.

The application can use the XmNprocessDragCallback list to imple-
ment particular processing for Motif's drag-and-drop.

XmNresizeCallback
Callbacks on the XmNresizeCallback list are called when the Xbae-
Matrix widget is resized. A pointer to the following structure is
passed to
each callback on the XmNresizeCallback list:

typedef struct
{
XbaeReasonType reason;
XEvent *event;
int row;
int column;
Dimension width;
Dimension height;
} XbaeMatrixResizeCallbackStruct;

reason Set to XbaeResizeReason.

event Always set to NULL

row Set to the number of rows in the matrix (provided for
convenience).

column Set to the number of colums in the matrix (provided for
convenience).

width The new width of the XbaeMatrix widget.

height The new height of the XbaeMatrix widget.

The application can use the XmNresizeCallback to adjust such re-
sources as XmNcolumnWidths, XmNvisibleColumns and XmNvisibleRows
when the widget containing an XbaeMatrix widget is resized.

XmNresizeColumnCallback
Callbacks on the XmNresizeColumnCallback list are called when a
column of the XbaeMatrix widget is dynamically resized by the
user. A pointer to the following structure is passed to each
callback on the XmNresizeColumnCallback list:

typedef struct
{
XbaeReasonType reason;
XEvent *event;
int row;
int column;
int which;
int columns;
short *column_widths;
} XbaeMatrixResizeColumnCallbackStruct;

reason Set to XbaeResizeColumnReason.

event The XEvent that ended the resize. The event will be of
type XButtonReleasedEvent.

row The row in which the ResizeColumn() action began.

column The column in which the ResizeColumn() action began (and
ended).

which The column that was resized in the ResizeColumn() ac-
tion.

columns The number of columns in the XbaeMatrix widget.

column_widths
The widths of each column as they stand after the Re-
sizeColumn() action.

The application can use the XmNresizeColumnCallback to perform
post processing after a column has been resized. By adjusting the
values contained in column_widths the XbaeMatrix widget will use
the values upon return from the callback. Changing the number of
columns in the matrix in the XmNresizeColumnCallback should be
used carefully as it may cause unexpected results.

XmNselectCellCallback
Callbacks on the XmNselectCellCallback list are called from the
SelectCell() action. The application can bind the SelectCell() ac-
tion to any pointer based event. When this event occurs, Select-
Cell() will call the callbacks on the XmNselectCellCallback list.
A pointer to the following structure is passed to each callback on
the XmNselectCellCallback list:

typedef struct
{
XbaeReasonType reason;
XEvent *event;
int row;
int column;
Boolean **selected_cells;
String **cells;
Cardinal num_params;
String *params;
} XbaeMatrixSelectCellCallbackStruct;

reason Set to XbaeSelectCellReason.

event The XEvent which invoked the SelectCell() action.

row The row number of the cell which was selected.

column The column number of the cell which was selected.

selected_cells
The value of the XmNselectedCells resource. This is pro-
vided as a convenience to the application and will be
NULL if no cells have yet been selected.

cells The value of the XmNcells resource. This is provided as
a convenience to the application and will be NULL if no
cells have been specified or the XmNdrawCellCallback is
being used.

num_params
The number of String parameters passed to the Select-
Cell() action.

params An array containing the num_params String parameters
passed to the SelectCell() action.

The application can use the XmNselectCellCallback list to imple-
ment it's own selection model. The XbaeMatrixSelectCellCallback-
Struct contains the array of String parameters passed to the Se-
lectCell() action which invoked this callback. By binding the Se-
lectCell() action to various events via the translation manager,
and using String action parameters to distinguish them, the appli-
cation can implement various selection models. For example, the
following translations could be used to implement a model in which
a modifier key indicates whether a single cell or an entire row
should be selected. The callbacks on the XmNselectCellCallback
list would examine the parameter and take the appropriate action.

#override\n\
Shift<Btn1Down>: SelectCell(cell)\n\
Ctrl<Btn1Down>: SelectCell(row)

The callbacks on the XmNselectCellCallback list can also be used
in other ways, e.g. to pop up a cell specific menu.

NOTE: If no cells have been selected, the value of selected_cells
will be NULL. The same applies for cells. Care must be taken so
as not to dereference these members of the callback struct.

XmNtrackCellCallback
Callbacks on the XmNtrackCellCallback list are being called by the
HandleTracking() action, which is triggered by pointer motion.
One of the purposes of this callback list is to figure out from
which cell to which cell the pointer is being moved. A pointer to
the XbaeMatrixTrackCellCallbackStruct structure is being passed.
Its fields are defined as :

typedef struct _XbaeMatrixTrackCellCallbackStruct
{
XbaeReasonType reason;
XEvent *event;
int row, column;
int prev_row, prev_column;
Position pointer_x, pointer_y;
} XbaeMatrixTrackCellCallbackStruct;

reason Set to XbaeSelectCellReason.

event The XEvent which invoked the HandleTracking() action.

row This is the row number that the pointer is currently in.

column This is the column number that the pointer is currently
in.

prev_row The row that the pointer was previously in.

prev_column
The column that the pointer was previously in.

pointer_x The x position of the pointer.

pointer_y The y position of the pointer.

XmNtraverseCellCallback
Callbacks on the XmNtraverseCellCallback list are called from the
EditCell() action and when XbaeMatrix receives or looses focus.
The application can customize cell traversal using these call-
backs. XbaeMatrix has a default traversal order, outlined below,
which the application can override. A pointer to the following
structure is passed to each callback on the XmNtraverseCellCall-
back list:

typedef struct
{
XbaeReasonType reason;
XEvent *event;
int row;
int column;
int next_row;
int next_column;
int fixed_rows;
int fixed_columns;
int trailing_fixed_rows;
int trailing_fixed_columns;
int num_rows;
int num_columns;
String param;
XrmQuark qparam;
} XbaeMatrixTraverseCellCallbackStruct;

reason Set to XbaeTraverseCellReason.

event The event that invoked this callback.

row The row number of the cell currently being edited.

column The column number of the cell currently being edited.

next_row The row number of the next cell to be edited, this can
be changed by the application.

next_column
The column number of the next cell to be edited, this
can be changed by the application.

fixed_rows
The value of the XmNfixedRows resource. This is provided
as a convenience for the application in calculating the
next_row and next_column fields.

fixed_columns
The value of the XmNfixedColumns resource. This is pro-
vided as a convenience for the application in calculat-
ing the next_row and next_column fields.

trailing_fixed_rows
The value of the XmNtrailingFixedRows resource. This is
provided as a convenience for the application in calcu-
lating the next_row and next_column fields.

trailing_fixed_columns
The value of the XmNtrailingFixedColumns resource. This
is provided as a convenience for the application in cal-
culating the next_row and next_column fields.

num_rows The value of the XmNrows resource. This is provided as a
convenience for the application in calculating the
next_row and next_column fields.

num_columns
The value of the XmNcolumns resource. This is provided
as a convenience for the application in calculating the
next_row and next_column fields.

param The String value of the parameter passed to the Edit-
Cell() action.

qparam The XrmQuark value of the parameter passed to the Edit-
Cell() action.

The EditCell() action takes an arbitrary parameter which it passes
through to the callbacks on the XmNtraverseCellCallback list in
both String and XrmQuark forms. The EditCell() action recognizes
five special parameters which it uses to implement it's default
cell traversal. These parameters and their corresponding traversal
results are:

Pointer Set next_row and next_column to the cell underneath the
mouse pointer.

Left If we are currently editing cell (XmNfixedRows, XmN-
fixedColumns), then do not move. Otherwise move one col-
umn to the left, if that column is less than XmNfixed-
Columns , then move up to the last column of the row
above.

Right If we are currently editing cell (XmNrows - 1, XmN-
columns - 1), then do not move. Otherwise move one col-
umn to the right, if that column is greater than or
equal to XmNcolumns , then move down to column XmNfixed-
Columns of the row below.

Up Move up one row. If that row is less than XmNfixedRows ,
then move to the last row.

Down Move down one row. If that row is greater than or equal
to XmNrows , then move to row XmNfixedRows.

If the EditCell() action recognizes one of these special parame-
ters, it calculates the new cell to be edited accordingly and
stores the results in the next_row and next_column fields of the
XbaeMatrixTraverseCellCallbackStruct. If EditCell() does not rec-
ognize it's parameter, it sets next_row and next_column to the
current row and column. It also stores a String and XrmQuark ver-
sion of it's parameter in the param and qparam fields. EditCell()
then calls the callbacks on the XmNtraverseCellCallback list.
These callbacks can examine the parameter and recalculate the
next_row and next_column fields appropriately. The application
can override the default calculation for the special parameters,
or it can define an entirely new parameter with a corresponding
new calculation. It would do this by binding EditCell() with a
new application specific parameter to an event in a translation
table. It is expected that application callbacks will use the Xr-
mQuark version of the parameter for efficiency reasons (by stati-
cally creating the new XrmQuarks and comparing them against the
incoming qparam).

When XbaeMatrix receives the focus it will also call the XmNtra-
verseCellCallback callbacks before returning to the current cell
or the upper left most visible cell if no cell is currently
edited. The XbaeMatrixTraverseCellCallbackStruct will have param
and qparm set to Focus. If there is no current cell row and col-
umn will be set to -1.

When XbaeMatrix looses the focus it will also call the XmNtraver-
seCellCallback with param and qparm set to LoosingFocus.

XmNvalueChangedCallback
Callbacks on the XmNvalueChangedCallback list are called while a
cell is being edited. The callbacks are called after text is in-
serted into or deleted from the TextField edit widget. A pointer
to the following structure is passed to each callback on the XmN-
valueChangedCallback list:

typedef struct
{
XbaeReasonType reason;
XEvent *event;
int row;
int column;
} XbaeMatrixValueChangedCallbackStruct;

reason Set to XbaeValueChangedReason.

event The event that triggered this callback.

row The row number of the cell being edited.

column The column number of the cell being edited.

XmNwriteCellCallback
Callbacks (although it probably only makes sense to have one) on
the XmNwriteCellCallback list are called when the widget needs to
write data to a cell, but only when XmNdrawCellCallback is de-
fined. A pointer to the following structure is passed to each
callback on the XmNwriteCellCallback list:

typedef struct
{
XbaeReasonType reason;
XEvent *event;
int row;
int column;
XbaeCellType type;
String string;
Pixmap pixmap;
Pixmap mask;
} XbaeMatrixWriteCellCallbackStruct;

reason Set to XbaeWriteCellReason.

event Always set to NULL

row The row number of the cell that needs to be written.

column The column number of the cell that needs to be written.

type The type of ``data'' contained in the cell, either
XbaeString or XbaePixmap.

string The string to store if type is set to XbaeString.

pixmap The pixmap to store if type is set to XbaePixmap.
(maybe a little meaningless unless you can edit a pixmap
in a cell)

mask A mask for the pixmap as obtained from the XPM library.
mask is only necessary when pixmap has a depth greater
than one.

If the application adds this callback, when the XbaeMatrix is ed-
itable and has been assigned an XmNdrawCellCallback, data on the
widget can be edited and stored back in the application's data
structure. Only if an XmNdrawCellCallback has been assigned to
the XbaeMatrix widget, will the XmNwriteCellCallback be called.

At the moment, pixmap and mask will be sent to the XmNwriteCell-
Callback as NULL.

Translations
XbaeMatrix inherits translations from XmManager. In addition, XbaeMa-
trix uses the following translation:
:<Btn1Up>: DefaultAction()\n\
:<Btn1Down>: DefaultAction() EditCell(Pointer)\n\
:Shift<Btn2Down>: ResizeColumns()\n\
:<Btn2Down>: ProcessDrag()\n\
:<Btn1Motion>: HandleMotion() HandleTracking()()\n\
:<Motion>: HandleTracking()()\n\
:<Btn4Down>: ScrollRows(-50)()\n\
:<Btn5Down>: ScrollRows( 50)()

XbaeMatrix installs the following default XmNtextTranslations on the
TextField edit widget:
#override\n\
Shift ~Ctrl ~Meta ~Alt <Key>Tab: EditCell(Left)\n\
~Ctrl ~Meta ~Alt <Key>Tab: EditCell(Right)\n\
<Key>osfUp: EditCell(Up)\n\
<Key>osfDown: EditCell(Down)\n\
<Key>osfActivate: CommitEdit(False)\n\
~Shift ~Meta ~Alt <Key>Return: CommitEdit(False)\n\
<Key>osfCancel: CommitEdit(False)\n\
Shift Ctrl ~Meta ~Alt <Key>Tab: TraversePrev()\n\
Ctrl ~Meta ~Alt <Key>Tab: TraverseNext()\n\
<Key>osfPageDown: PageDown()\n\
<Key>osfPageUp: PageUp()\n

Action Routines
CancelEdit()
If the single parameter to CancelEdit() is the String True, then
it unmaps the edit TextField, discarding any changes which were
made to the cell being edited. If the parameter is False, then
CancelEdit() restores the edit TextField to the original con-
tents of the cell, discarding any changes made to the cell being
edited. The TextField is not unmapped.

CommitEdit()
CommitEdit() first calls any callbacks on the XmNleaveCellCall-
back list to determine if the changes made to the current cell
are valid. If they are, it then saves any changes made to the
cell into the cell. If the callbacks on the XmNleaveCellCallback
list return that the changes are not valid, CommitEdit() does
nothing.

If the changes are valid, CommitEdit() examines it's one parame-
ter, which must be the string True or False. If the parameter is
True, then the edit TextField is unmapped. If it is False, then
the TextField is not unmapped.

DefaultAction()
DefaultAction() sets up a mechanism for determining whether two
successive mouse clicks form a double click. The DefaultAc-
tion() should normally be used in conjunction with other pointer
based events and provides a mechanism for acting on double
clicks in a cell.

EditCell()
EditCell() edits a new cell. EditCell() first calculates the new
cell to edit based on it's single parameter. It then calls the
callbacks on the XmNtraverseCellCallback list to allow them to
specify a different cell to edit (see the discussion of XmNtra-
verseCellCallback above). EditCell() then calls the callbacks
on the XmNleaveCellCallback list to determine if the changes
made to the current cell are valid. If they are, it then saves
any changes made to the cell into the cell. If the changes are
not valid, EditCell() does nothing further.

If the changes are valid, EditCell() attempts to scroll the new
cell to be edited so that it is fully visible. If the new cell
is in a fixed row or column, EditCell() returns and does nothing
further (these cells are not editable). Otherwise, EditCell()
calls the callbacks on the XmNenterCellCallback list to deter-
mine if the new cell is editable. It then moves the XmText edit
widget to the new cell, setting it's editability based on the
return from the XmNenterCellCallback callbacks.

ProcessDrag()
ProcessDrag() calls the callbacks on the XmNprocessDragCallback
list, passing them a pointer to a XbaeMatrixProcessDragCallback-
Struct.

ResizeColumns()
Allows the user to dynamically resize the column widths, pro-
vided that XmNallowColumnResize is True.

ScrollRows()
ScrollRows() makes the rows of the matrix scroll by the pixel
amount specified by it's argument.

ScrollColumns()
ScrollColumns() makes the columns of the matrix scroll by the
pixel amount specified by it's argument.

SelectCell()
SelectCell() calls the callbacks on the XmNselectCellCallback
list, passing them a pointer to a XbaeMatrixSelectCellCallback-
Struct. This structure will contain the String parameters
passed to the SelectCell() action, among other things (see the
discussion of XmNselectCellCallback above).

TraverseNext()
TraverseNext() will traverse out of the Matrix and into the next
tab group.

TraversePrev()
TraversePrev() will traverse out of the Matrix and into the pre-
vious tab group.

PageDown()
PageDown() causes the Matrix to scroll down a full page. The
text widget is placed on the first non fixed row of the new
page.

PageUp()
PageUp() causes the Matrix to scroll up a full page. The text
widget is placed on the first non fixed row of the new page.

Type Converters
In addition to the standard type converters registered by Xt and Motif,
XbaeMatrix registers the following additional type converters:

CvtStringToStringArray()
Converts a comma separated list of Strings to an array of String
pointers, one for each substring. Commas in the list may be es-
caped with the character `\'. This converter allows the XmN-
rowLabels and XmNcolumnLabels resources to be specified in re-
source files.

CvtStringToWidthArray()
Converts a comma separated list of numeric Strings to an array
of short integers. This converter allows the XmNcolumnWidths re-
source to be specified in resource files.

CvtStringToMaxLengthArray()
Converts a comma separated list of numeric Strings to an array
of integers. This converter allows the XmNcolumnMaxLengths re-
source to be specified in resource files.

CvtStringToAlignmentArray()
Converts a comma separated list of alignments to an array of un-
signed chars. This converter allows the XmNcolumnLabelAlignments
and XmNcolumnAlignments resources to be specified in resource
files.

CvtStringToGridType()
Converts a single string as discussed in XmNgridType to a grid
type value. This converter allows XmNgridType to be specified
in resource files.

CvtStringToMatrixScrollBarDisplayPolicy()
Converts a single string as discussed in XmNhorizontalScroll-
BarDisplayPolicy and XmNverticalScrollBarDisplayPolicy to a dis-
play policy value. This converter allows XmNhorizontalScroll-
BarDisplayPolicy and XmNverticalScrollBarDisplayPolicy to be
specified in resource files.

CvtStringToCellTable()
Converts a comma separated list of Strings with \n delimited
rows to a two dimensional array of String pointers. This con-
verter allows the XmNcells resource to be specified in resource
files.

CvtStringToPixelTable()
Converts a comma separated list of color names with \n delimited
rows to a two dimensional array of Pixel values. This converter
allows the XmNcellBackgroundsandXmNcolors resources to be speci-
fied in resource files.

CvtStringToBooleanArray()
Converts a comma separated list of string or numeric values to
an array of Booleans. The converter recongnises a comma sepa-
rated list of values. Each value is parsed such that if the
first character is This converter allows the XmNcolumnButtonLa-
bels and XmNrowButtonLabels resources to be specified in re-
source files.

Public Functions
The following external entry points to XbaeMatrix class methods are de-
fined:

XbaeCreateMatrix()

Widget XbaeCreateMatrix()

ArgList arglist;
Cardinal argcount;

parent Specifies the parent widget ID.

name Specifies the name of the created widget

arglist Specifies the argument list

argcount Specifies the number of attribute/value pairs in the
argument list (arglist)

XbaeCreateMatrix() creates an unmanaged instance of an XbaeMa-
trix widget and returns the associated widget ID.

XbaeMatrixAddColumns()

void XbaeMatrixAddColumns()
Widget w;
int position;
String *columns;
String *labels;
short *widths;
int *max_lengths;
unsigned char *alignments;
unsigned char *label_alignments;
Pixel *colors;
int num_columns;

w An XbaeMatrix widget.

position The column position before which to add the new
columns. Must be greater than or equal to zero, and
less than or equal to XmNcolumns.

columns Points to an ordinary two dimensional array of String,
or NULL. These Strings will be used to modify the Xm-
Ncells resource to populate the new columns. Each row
in the array must have XmNrows elements and represents
one of the new columns. columns must have num_columns
rows. If columns is NULL, empty columns will be added.

labels Points to an array of String, or NULL. These Strings
will be used as the XmNcolumnLabels for the new
columns. The labels array must have num_columns ele-
ments. If labels is NULL, and XmNcolumnLabels is set,
then blank column labels will be used.

widths Points to an array of short or NULL. These values
will be used as the XmNcolumnWidths for the new
columns. The widths array must have num_columns ele-
ments. if widths is NULL then a default width will be
used for the new columns.

max_lengths
Points to an array of int, or NULL. These values will
be used as the XmNcolumnMaxLengths for the new
columns. The max_lengths array must have num_columns
elements. If max_lengths is NULL, then the correspond-
ing value from widths will be used.

alignments
Points to an array of unsigned char, or NULL. These
values will be used as the XmNcolumnAlignments for the
new columns. The alignments array must have
num_columns elements. If alignments is NULL, then XmA-
LIGNMENT_BEGINNING will be used.

label_alignments
Points to an array of unsigned char, or NULL. These
values will be used as the XmNcolumnLabelAlignments
for the new column labels. The label_alignments array
must have num_columns elements. If label_alignments is
NULL, then XmALIGNMENT_BEGINNING will be used.

colors Points to an array of Pixel, or NULL. These values
will be used to set the corresponding columns in the
XmNcolors table for the new columns. The colors array
must have num_columns elements. If colors is NULL,
then XmNforeground will be used.

num_columns
The number of columns which are being added to the
widget.

XbaeMatrixAddColumns() allows the application developer to dy-
namically add new columns anywhere in the Matrix. The columns
will be added before the column specified in position. Columns
are numbered starting at zero. To append new columns onto the
end of the Matrix, specify position as the total number of
columns. Most of the arguments to XbaeMatrixAddColumns() may be
specified as NULL. Default values will be used by the widget.

If the programmer attempts to add columns using XbaeMatrixAdd-
Columns() when there are no rows, it will result in a warning
message. There must be at least one row in the XbaeMatrix wid-
get to add columns.

To maintain backward compatability, the cell backgrounds cannot
be set in a call to XbaeMatrixAddColumns() and must be set (if
so desired) in a separate call to XtVaSetValues().

XbaeMatrixAddRows()

void XbaeMatrixAddRows()
Widget w;
int position;
String *rows;
String *labels;
Pixel *colors;
int num_rows;

w An XbaeMatrix widget.

position The row position before which to add the new rows.
Must be greater than or equal to zero, and less than
or equal to XmNrows.

rows Points to an ordinary two dimensional array of String,
or NULL. These Strings will be used to modify the Xm-
Ncells resource to populate the new rows. Each row in
the array must have XmNcolumns elements and represents
one of the new rows. rows must have num_rows rows. If
rows is NULL, empty rows will be added.

labels Points to an array of String, or NULL. These Strings
will be used as the XmNrowLabels for the new rows. The
labels array must have num_rows elements. If labels is
NULL, and XmNrowLabels is set, then blank row labels
will be used

colors Points to an array of Pixel, or NULL. These values
will be used to set the corresponding rows in the XmN-
colors table for the new rows. The colors array must
have num_rows elements. If colors is NULL, then XmN-
foreground will be used.

num_rows The number of rows which are being added to the wid-
get.

XbaeMatrixAddRows() allows the application developer to dynami-
cally add new rows anywhere in the Matrix. The rows will be
added before the row specified in position. Rows are numbered
starting at zero. To append new rows onto the end of the Matrix,
specify position as the total number of rows.

To maintain backward compatability, the cell backgrounds cannot
be set in a call to XbaeMatrixAddRows() and must be set (if so
desired) in a separate call to XtVaSetValues().

XbaeMatrixCancelEdit()

void XbaeMatrixCancelEdit()
Widget w;
Boolean unmap;

w An XbaeMatrix widget.

unmap Specifies whether the TextField cell edit widget
should be unmapped after the edit is canceled.

XbaeMatrixCancelEdit() allows the application developer to pro-
grammatically cancel a cell edit in progress, discarding any
changes made by the user. This function unmaps the TextField
edit widget if the unmap flag is True. If unmap is False, the
contents of the TextField are restored to their original value,
and the TextField is not unmapped.

XbaeMatrixCommitEdit()

Boolean XbaeMatrixCommitEdit()
Widget w;
Boolean unmap;

w An XbaeMatrix widget.

unmap Specifies whether the TextField cell edit widget
should be unmapped after an edit is successfully com-
mitted.

XbaeMatrixCommitEdit() can be used by the application developer
to programmatically commit an edit, saving any changes made by
the user. This will cause the callbacks on the XmNleaveCell-
Callback list to be called to verify that the changes the user
made are valid. If the changes are valid, then they are saved
into the cell and if the unmap flag is True, the TextField wid-
get will be unmapped.

XbaeMatrixDeleteColumns()

void XbaeMatrixDeleteColumns()
Widget w;
int position;
int num_columns;

w An XbaeMatrix widget.

position The column position at which to begin deleting
columns. Must be greater than or equal to zero, and
(position + num_columns) must be less than or equal to
XmNcolumns.

num_columns
The number of columns to delete from the widget.

XbaeMatrixDeleteColumns() allows the application developer to
dynamically delete columns from anywhere in the Matrix. Columns
will be deleted starting at the column specified by position.

XbaeMatrixDeleteRows()

void XbaeMatrixDeleteRows()
Widget w;
int position;
int num_rows;

w An XbaeMatrix widget.

position The row position at which to begin deleting rows. Must
be greater than or equal to zero, and (position +
num_rows) must be less than or equal to XmNrows.

num_rows The number of rows to delete from the widget.

XbaeMatrixDeleteRows() allows the application developer to dy-
namically delete rows from anywhere in the Matrix. Rows will be
deleted starting at the row specified by position.

XbaeMatrixDeselectAll()

void XbaeMatrixDeselectAll()
Widget w;

w An XbaeMatrix widget.

XbaeMatrixDeselectAll() allows the application developer to pro-
grammatically deselect all cells. XbaeMatrixDeselectAll() re-
draws the cells in normal video. All Booleans in the XmNselect-
edCells array will be set to False.

XbaeMatrixDeselectCell()

void XbaeMatrixDeselectCell()
Widget w;
int row;
int column;

w An XbaeMatrix widget.

row The row of the cell to deselect.

column The column of the cell to deselect.

XbaeMatrixDeselectCell() allows the application developer to
programmatically deselect a cell. XbaeMatrixDeselectCell() re-
draws the cell in normal video. The corresponding Boolean in the
XmNselectedCells array will be set to False.

XbaeMatrixDeselectColumn()

void XbaeMatrixDeselectColumn()
Widget w;
int column;

w An XbaeMatrix widget.

column The column to deselect.

XbaeMatrixDeselectColumn() allows the application developer to
programmatically deselect a column. XbaeMatrixDeselectColumn()
draws the column in normal video. The corresponding Booleans in
the XmNselectedCells array will be set to False.

XbaeMatrixDeselectRow()

void XbaeMatrixDeselectRow()
Widget w;
int row;

w An XbaeMatrix widget.

int XbaeMatrixDisableRedisplay()
Widget w;

w An XbaeMatrix widget.

XbaeMatrixDisableRedisplay() and XbaeMatrixEnableRedisplay() al-
low an application to make multiple changes to a matrix without
immediate visual updates. When multiple changes are made with
redisplay enabled, visual flashing often occurs. These routines
help eliminate this problem.

int column;

w An XbaeMatrix widget.

row The row of the cell to be edited.

column The column of the cell to be edited.

XbaeMatrixEditCell()

allows the application developer to programmatically force a
specific cell to be edited. This function will first attempt to
commit the edit in the current cell. If the XmNleaveCellCallback
callbacks disallow this commit, then XbaeMatrixEditCell() will
return. Otherwise the specified cell is scrolled until it is
visible. If the specified cell is in a fixed row or column, it
cannot be edited and XbaeMatrixEditCell() will return. Next, the
callbacks on the XmNenterCellCallback callback list are called
for the specified cell to determine it's editability. Then the
TextField edit widget is mapped on top of the specified cell.

XbaeMatrixRefresh()

void XbaeMatrixRefresh()
Widget w;

w An XbaeMatrix widget.

XbaeMatrixRefresh() allows the application developer to force
the widget to redraw itself. This might be used when the pro-
grammer knows the widget's values have changed, but the widget
has not detected the change. For example, the quickest way to
swap the values of 2 rows would be to do an XtGetValues on XmN-
cells, swap the values of the 2 rows, and then do an XtSetValues
on XmNcells with the same StringTable variable. Because of the
way the Intrinsics work, the widget will not see this change and
will display the old values until a redraw is preformed because
of a resize or scroll event (assuming no other change in the
XtSetValues caused a redraw). Calling XbaeMatrixRefresh() will
cause the correct values to be drawn and overcome this limita-
tion in the Intrinsics. While this function should rarely be
needed, it is provided ``just in case''.

XbaeMatrixRefreshCell()

Pixel *colors;
int num_colors;

w An XbaeMatrix widget.

position The row position at which to begin applying the new
colors. Must be greater than or equal to zero, and
(position + num_colors) must be less than or equal to
XmNrows.

colors Points to an array of Pixel. These specify the colors
for the cells in the specified rows. The colors array
must have num_colors elements.

num_colors
The number of colors in the colors array.

XbaeMatrixSetRowColors() is a convenient way to specify and mod-
ify the XmNcolors resource when setting the color of an entire
row or rows. If XmNcolors is NULL, then XbaeMatrixSetRowColors()
will create a Pixel table initialized to XmNforeground except
for the rows specified in it's arguments. If XmNcolors is not
NULL, then XbaeMatrixSetRowColors() will changed the specified
rows in that resource to the specified colors.

XbaeMatrixSetRowHeight()

void XbaeMatrixSetRowHeight()
Widget w;
int row;
int height;

w An XbaeMatrix widget.

row The row whose height we'll be changing.

height The new height of this row. A row height can be 0 to
hide a row.

XbaeMatrixSetRowHeight() is a convenient way to change the
height of a row without the need to allocate an array with row
height numbers. Passing -1 as the new height will reset the
row's height to the default value.

XbaeMatrixSortColumns allows you to sort the columns in the
XbaeMatrix widget according to criteria determined by the proc
function. The proc function should have the above signature and
functionality as demanded by the qsort(3) function. It will be
called with a the matrix being sorted, the indices of two
columns to compare and the user_data pointer XbaeMatrixSort-
Columns was called with. It should return -1, 0, or 1 as appro-
priate. It is guaranteed that the matrix does not change while
sorting and the necessary reordering will only take place after
the last call to proc has been made.

widget according to criteria determined by the proc function.
The proc function should have the above signature and function-
ality as demanded by the qsort(3) function. It will be called
with the matrix being sorted, the indices of two rows to compare
and the user_data pointer XbaeMatrixSortRows was called with. It
should return -1, 0, or 1 as appropriate. It is guaranteed that
the matrix does not change while sorting and the necessary re-
ordering will only take place after the last call to proc has
been made.

XbaeMatrixUnhighlightAll()

XbaeGetVersionNum()

int XbaeGetVersionNum()

XbaeGetVersionNum() is a function that returns the numeric rep-
resentation of the version of the Xbae library that your program
is working with. This is the run-time version of the Xbae wid-
gets, where XbaeVersion is a macro that represents the compile-
time version.

The numeric representation is a simple calculation based on the
major, minor, and pico numbers representing an Xbae widget re-
lease. E.g. version 4.8.1 would be represented as 40801.

Releases prior to 4.8.0 didn't have this functionality.

XbaeGetVersionText()

char * XbaeGetVersionText()

XbaeGetVersionText() is a function that returns the textual rep-
resentation of the version of the Xbae library that your program
is working with. This is the run-time version of the Xbae wid-
gets, where XbaeVersionTxt is a macro that represents the com-
pile-time version.

Additional Behavior
Using XtSetValues to set the Matrix's XmNwidth resource to 0 will cause
it to recompute it's horizontal size. It will request a new size which
results in XmNvisibleColumns columns being displayed. If XmNvisi-
bleColumns is 0, then it will request a new size such that it does not
need a horizontal ScrollBar (full horizontal size).

Using XtSetValues to set the Matrix's XmNheight resource to 0 will
cause it to recompute it's vertical size. It will request a new size
which results in XmNvisibleRows rows being displayed. If XmNvisibleRows
is 0, then it will request a new size such that it does not need a ver-
tical ScrollBar (full vertical size).

An XtSetValues on XmNvisibleRows will cause the Matrix to request a new
size which results in XmNvisibleRows non-fixed rows being displayed,
only if the new value is different than the old one.

An XtSetValues on XmNvisibleColumns will cause the Matrix to request a
new size which results in the first XmNvisibleColumns non-fixed columns
being displayed, only if the new value is different than the old one.

An XtSetValues on any other resource will not result in a request for a
new size. Setting other resources in conjunction with setting XmNwidth
and/or XmNheight to 0 allows for more control of the Matrix's geometry.

An XtSetValues setting XmNrowLabelWidth to 0 will cause XmNrowLabel-
Width to be set to the width of the longest row label.
