NAME
XmText -- The Text widget class

SYNOPSIS
#include <Xm/Text.h>

DESCRIPTION
Text provides a single-line and multiline text editor for customizing
both user and programmatic interfaces. It can be used for single-line
string entry, forms entry with verification procedures, and full-window
editing. It provides an application with a consistent editing system
for textual data. The screen's textual data adjusts to the application
writer's needs.

Text provides separate callback lists to verify movement of the insert
cursor, modification of the text, and changes in input focus. Each of
these callbacks provides the verification function with the widget in-
stance, the event that caused the callback, and a data structure spe-
cific to the verification type. From this information, the function can
verify if the application considers this to be a legitimate state
change and can signal the widget whether to continue with the action.

The user interface tailors a new set of translations. The default
translations provide key bindings for insert cursor movement, deletion,
insertion, and selection of text.

Text allows the user to select regions of text. Selection is based on
the model specified in the Inter-Client Communication Conventions Man-
ual (ICCCM). Text supports primary and secondary selection.

In some Asian languages, texts are drawn vertically. Also, some charac-
ters are displayed with 90-degree clockwise rotation, and other charac-
ters are mapped to vertical glyphs that differ from the normal horiza-
ontal glyphs. Information about which characters require rotation or
mapping to vertical glyphs is specified in the X Locale Database (NLS
databases) and handled by X library, depending on XNOrientation XOC
values. XmText widget should also handle the vertically aligned lines
as for editing, entering, or selecting texts.

The vertical writing feature of the XmText widget is enabled when the
XmTOP_TO_BOTTOM value is specified for the XmNlayoutDirection resource
of the XmText widget. In that case, the horizontal scroll bar is dis-
played on the bottom of the XmText widget and the vertical scroll bar
is displayed on the left side.

Mouse Selection
The Text widget allows text to be edited, inserted, and selected. The
user can cut, copy, and paste text by using the clipboard, primary
transfer, or secondary transfer. Text also provides a Drag and Drop
facility that enables the user to copy or move data within Text or to a
different widget. When keyboard focus policy is set to EXPLICIT, the
widget that receives focus is the destination widget. In POINTER mode,
any keyboard or mouse operation (except secondary selection) in an ed-
itable widget establishes that widget as the destination.

If a destination widget becomes insensitive or uneditable, it forfeits
its destination status. In EXPLICIT mode, when a widget becomes insen-
sitive, the focus moves to another widget. If that widget is editable,
it becomes the destination widget; otherwise, there is no destination
widget. The text of any insensitive Text widget is stippled, indicating
its state to the user.

The insertion cursor, displayed as an I-beam, shows where input is in-
serted. Input is inserted just before the insertion cursor.

Text uses the XmQTnavigator, XmQTspecifyRenderTable, and XmQTscroll-
Frame traits, and holds the XmQTaccessTextual and XmQTtransfer traits.
The widget checks its parent for the XmQTscrollFrame trait. If this
trait does not exist, then the widget has no scrolling. If the trait
does exist, and the ScrollFrame widget has not been initialized, the
widget creates two navigators and sets up the scrollbars.

If an application or widget calls the setValue trait method of XmQTac-
cessTextual, then XmText will call XmTextSetString to set the string
value.

Classes
Text inherits behavior, resources, and traits from Core and XmPrimi-
tive.

The class pointer is xmTextWidgetClass.

The class name is XmText.

Data Transfer Behavior
Text supports transfer of the primary, secondary, and clipboard selec-
tions and dragging of selected text from the widget. Text can also be
the destination for the primary, secondary, and clipboard selections,
and it supports dropping of data being dragged onto the widget.

When the XmNconvertCallback procedures are called, the location_data
member of the XmConvertCallbackStruct member is NULL if the selected
text is being transferred. If the entire text, not the selected text,
is being transferred, the value of this member is the widget ID of the
Text widget.

As a source of data, Text supports the following targets and associated
conversions of data to these targets:

locale If the locale target matches the widget's locale, the widget
transfers the selected text in the encoding of the locale.

COMPOUND_TEXT
The widget transfers the selected text as type COMPOUND_TEXT.

STRING The widget transfers the selected text as type STRING.

TEXT If the selected text is fully convertible to the encoding of
the locale, the widget transfers the selected text in the en-
coding of the locale. Otherwise, the widget transfers the
selected text as type COMPOUND_TEXT.

UTF8_STRING
The widget transfers the selected text as type UTF8_STRING.

DELETE The widget deletes the selected text.

_MOTIF_CLIPBOARD_TARGETS
The widget transfers, as type ATOM, a list of the targets to
which the widget can convert data to be placed on the clip-
board immediately. If the selected text is fully convertible
to STRING, these include STRING; otherwise, they include COM-
POUND_TEXT.

_MOTIF_DEFERRED_CLIPBOARD_TARGETS
The widget transfers, as type ATOM, a list of the targets it
supports for delayed transfer for the CLIPBOARD selection.
This widget currently supplies no targets for _MOTIF_DE-
FERRED_CLIPBOARD_TARGETS.

_MOTIF_EXPORT_TARGETS
The widget transfers, as type ATOM, a list of the targets to
be used as the value of the DragContext's XmNexportTargets in
a drag-and-drop transfer. These include COMPOUND_TEXT,
UTF8_STRING, the encoding of the locale, STRING, TEXT, BACK-
GROUND, and FOREGROUND.

_MOTIF_LOSE_SELECTION
The widget takes the following actions:

• When losing the PRIMARY selection, it unhighlights the
selected text and calls the XmNlosePrimaryCallback pro-
cedures.

• When losing the SECONDARY selection, it removes the
secondary selection highlight.

• When losing the _MOTIF_DESTINATION selection, if the
widget does not have focus, it changes the cursor to
indicate that the widget is no longer the destination.

As a source of data, Text also supports the following standard Motif
targets:

BACKGROUND
The widget transfers XmNbackground as type PIXEL.

CLASS The widget finds the first shell in the widget hierarchy that
has a WM_CLASS property and transfers the contents as text in
the current locale.

CLIENT_WINDOW
The widget finds the first shell in the widget hierarchy and
transfers its window as type WINDOW.

COLORMAP The widget transfers XmNcolormap as type COLORMAP.

FOREGROUND
The widget transfers XmNforeground as type PIXEL.

NAME The widget finds the first shell in the widget hierarchy that
has a WM_NAME property and transfers the contents as text in
the current locale.

TARGETS The widget transfers, as type ATOM, a list of the targets it
supports. These include the standard targets in this list.
These also include COMPOUND_TEXT, UTF8_STRING, the encoding
of the locale, STRING, and TEXT.

TIMESTAMP The widget transfers the timestamp used to acquire the selec-
tion as type INTEGER.

_MOTIF_RENDER_TABLE
The widget transfers XmNrenderTable if it exists, or else the
default text render table, as type STRING.

_MOTIF_ENCODING_REGISTRY
The widget transfers its encoding registry as type STRING.
The value is a list of NULL separated items in the form of
tag encoding pairs. This target symbolizes the transfer tar-
get for the Motif Segment Encoding Registry. Widgets and ap-
plications can use this Registry to register text encoding
formats for specified render table tags. Applications access
this Registry by calling XmRegisterSegmentEncoding and
XmMapSegmentEncoding.

As a destination for data, Text chooses a target and requests conver-
sion of the selection to that target. If the encoding of the locale is
present in the list of available targets, Text chooses a requested tar-
get from the available targets in the following order of preference:

1. The encoding of the locale

2. TEXT

4. UTF8_STRING

3. COMPOUND_TEXT

4. STRING

If the encoding of the locale is not present in the list of available
targets, Text chooses a requested target from the available targets in
the following order of preference:

4. UTF8_STRING

1. COMPOUND_TEXT

2. STRING

New Resources
The following table defines a set of widget resources used by the pro-
grammer to specify data. The programmer can also set the resource val-
ues for the inherited classes to set attributes for this widget. To
reference a resource by name or by class in a .Xdefaults file, remove
the XmN or XmC prefix and use the remaining letters. To specify one of
the defined values for a resource in a .Xdefaults file, remove the Xm
prefix and use the remaining letters (in either lowercase or uppercase,
but include any underscores between words). The codes in the access
column indicate if the given resource can be set at creation time (C),
set by using XtSetValues (S), retrieved by using XtGetValues (G), or is
not applicable (N/A).

1 This resource cannot be set in a resource file.

XmNactivateCallback
Specifies the list of callbacks that is called when the user
invokes an event that calls the activate() action. The type
of the structure whose address is passed to this callback is
XmAnyCallbackStruct. The reason sent by the callback is
XmCR_ACTIVATE.

XmNautoShowCursorPosition
Ensures that the visible text contains the insert cursor when
set to True. If the insert cursor changes, the contents of
Text may scroll in order to bring the insertion point into
the window. Setting this resource to False, however, does
not ensure that Text will not scroll.

XmNcursorPosition
Indicates the position in the text where the current insert
cursor is to be located. Position is determined by the num-
ber of characters from the beginning of the text. The first
character position is 0 (zero).

XmNcursorPositionVisible
If the widget has an XmPrintShell as one of its ancestors,
then the default value is False; otherwise, it is True.

XmNdestinationCallback
Specifies a list of callbacks called when the widget is the
destination of a transfer operation. The type of the struc-
ture whose address is passed to these callbacks is XmDestina-
tionCallbackStruct. The reason is XmCR_OK.

XmNeditable
When set to True, indicates that the user can edit the text
string. Prohibits the user from editing the text when set to
False.

When XmNeditable is used on a widget it sets the dropsite to
XmDROP_SITE_ACTIVE.

XmNeditMode
Specifies the set of keyboard bindings used in Text. The de-
fault, XmSINGLE_LINE_EDIT, provides the set of key bindings
to be used in editing single-line text. XmMULTI_LINE_EDIT
provides the set of key bindings to be used in editing multi-
line text.

The results of placing a Text widget inside a ScrolledWindow
when the Text's XmNeditMode is XmSINGLE_LINE_EDIT are unde-
fined.

XmNfocusCallback
Specifies the list of callbacks called when Text accepts in-
put focus. The type of the structure whose address is passed
to this callback is XmAnyCallbackStruct. The reason sent by
the callback is XmCR_FOCUS.

XmNgainPrimaryCallback
Specifies the list of callbacks called when an event causes
the Text widget to gain ownership of the primary selection.
The reason sent by the callback is XmCR_GAIN_PRIMARY.

XmNlosePrimaryCallback
Specifies the list of callbacks called when an event causes
the Text widget to lose ownership of the primary selection.
The reason sent by the callback is XmCR_LOSE_PRIMARY.

XmNlosingFocusCallback
Specifies the list of callbacks called before Text loses in-
put focus. The type of the structure whose address is passed
to this callback is XmTextVerifyCallbackStruct. The reason
sent by the callback is XmCR_LOSING_FOCUS.

XmNmarginHeight
Specifies the distance between the top edge of the widget
window and the text, and between the bottom edge of the wid-
get window and the text.

XmNmarginWidth
Specifies the distance between the left edge of the widget
window and the text, and between the right edge of the widget
window and the text.

XmNmaxLength
Specifies the maximum length of the text string that can be
entered into text from the keyboard. This value must be non-
negative. Strings that are entered by using the XmNvalue re-
source or the XmTextSetString function ignore this resource.

XmNmodifyVerifyCallback
Specifies the list of callbacks called before text is deleted
from or inserted into Text. The type of the structure whose
address is passed to this callback is XmTextVerifyCallback-
Struct. The reason sent by the callback is XmCR_MODIFY-
ING_TEXT_VALUE. When multiple Text widgets share the same
source, only the widget that initiates the source change will
generate XmNmodifyVerifyCallback.

If both XmNmodifyVerifyCallback and XmNmodifyVerifyCallback-
Wcs are registered callback lists, the procedure(s) in the
XmNmodifyVerifyCallback list is always executed first; and
the resulting data, which may have been modified, is passed
to the XmNmodifyVerifyCallbackWcs callback routines.

XmNmodifyVerifyCallbackWcs
Specifies the list of callbacks called before text is deleted
from or inserted into Text. The type of the structure whose
address is passed to this callback is XmTextVerifyCallback-
StructWcs. The reason sent by the callback is XmCR_MODIFY-
ING_TEXT_VALUE. When multiple Text widgets share the same
source, only the widget that initiates the source change will
generate the XmNmodifyVerifyCallbackWcs.

XmNmotionVerifyCallback
Specifies the list of callbacks called before the insert cur-
sor is moved to a new position. The type of the structure
whose address is passed to this callback is XmTextVerifyCall-
backStruct. The reason sent by the callback is XmCR_MOV-
ING_INSERT_CURSOR. It is possible for more than one XmNmo-
tionVerifyCallback to be generated from a single action.

XmNsource Specifies the source with which the widget displays text. If
no source is specified, the widget creates a default string
source. This resource can be used to share text sources be-
tween Text widgets.

XmNtopCharacter
Displays the position of text at the top of the window. Po-
sition is determined by the number of characters from the be-
ginning of the text. The first character position is 0
(zero).

If the XmNeditMode is XmMULTI_LINE_EDIT, the line of text
that contains the top character is displayed at the top of
the widget without shifting the text left or right. XtGet-
Values for XmNtopCharacter returns the position of the first
character in the line that is displayed at the top of the
widget.

XmNtotalLines
Indicates the number of lines in the text widget buffer (not
necessarily visible). The initial value 1 means the text
buffer is empty. The number of lines reported takes into ac-
count the wordWrap policy (that is, it's not simply the num-
ber of newline characters.

XmNvalue Specifies the string value of the Text widget as a char* data
value. Moves the cursor to position 0 unless a value of XmN-
cursorPosition was explicitly supplied in the argument list.
If XmNvalue and XmNvalueWcs are both defined, the value of
XmNvalueWcs supersedes that of XmNvalue. XtGetValues returns
a copy of the value of the internal buffer and XtSetValues
copies the string values into the internal buffer.

XmNvalueChangedCallback
Specifies the list of callbacks called after text is deleted
from or inserted into Text. The type of the structure whose
address is passed to this callback is XmAnyCallbackStruct.
The reason sent by the callback is XmCR_VALUE_CHANGED. When
multiple Text widgets share the same source, only the widget
that initiates the source change will generate the XmNval-
ueChangedCallback. This callback represents a change in the
source in the Text, not in the Text widget. The XmNval-
ueChangedCallback should occur only in pairs with an XmNmodi-
fyVerifyCallback, assuming that the doit flag in the callback
structure of the XmNmodifyVerifyCallback is not set to False.

XmNvalueWcs
Specifies the string value of the Text widget as a wchar_t*
data value. Moves the cursor to position 0 unless a value of
XmNcursorPosition was explicitly supplied in the argument
list.

This resource cannot be specified in a resource file.

If XmNvalue and XmNvalueWcs are both defined, the value of
XmNvalueWcs supersedes that of XmNvalue. XtGetValues returns
a copy of the value of the internal buffer encoded as a wide
character string. XtSetValues copies the value of the wide
character string into the internal buffer.

XmNverifyBell
Specifies whether the bell should sound when the verification
returns without continuing the action. The default depends
on the value of the ancestor VendorShell's XmNaudibleWarning
resource.
+--------------------------------------------------------------------------------------+
| XmText Input Resource Set |
| Name Class Type Default Access |
| XmNpendingDelete XmCPendingDelete Boolean True CSG |
| XmNselectionArray XmCSelectionArray XtPointer default array CSG |
| XmNselectionArrayCount XmCSelectionArrayCount int 4 CSG |
| XmNselectThreshold XmCSelectThreshold int 5 CSG |
+--------------------------------------------------------------------------------------+

XmNpendingDelete
Indicates that pending delete mode is on when the Boolean
value is True. Pending deletion is defined as deletion of
the selected text when an insertion is made.

XmNselectionArray
Defines the actions for multiple mouse clicks. The value of
the resource is an array of XmTextScanType elements. Xm-
TextScanType is an enumeration indicating possible actions.
Each mouse click performed within some time of the previous
mouse click increments the index into this array and performs
the defined action for that index. (This "multiclick" time is
specified by the operating environment, and varies among dif-
ferent systems. In general, it is usually set to some frac-
tion of a second.) The possible actions in the order they oc-
cur in the default array are as follows:

3. XmSELECT_POSITION, which resets the insert cursor posi-
tion.

4. XmSELECT_WORD, which selects a word.

5. XmSELECT_LINE, which selects a line of text. This ac-
tion sees a line as delimited by hard newline charac-
ters. In other words, if the word wrap feature is on
(XmNwordWrap is True), this will ignore the newlines
automatically inserted by the widget. This is the de-
fault.

6. XmSELECT_OUT_LINE, which selects a line of text. This
action sees a line as delimited by hard or soft newline
characters. In other words, if the word wrap feature is
on (XmNwordWrap is True), the newlines automatically
inserted by the widget will be treated as delimiting
lines.

7. XmSELECT_ALL, which selects all of the text.

XmNselectionArrayCount
Indicates the number of elements in the XmNselectionArray re-
source. The value must not be negative.

XmNselectThreshold
Specifies the number of pixels of motion that is required to
select the next character when selection is performed using
the click-drag mode of selection. The value must not be neg-
ative. This resource also specifies whether a drag should be
started and the number of pixels to start a drag when
Btn2Down and Btn1Down are integrated.
+----------------------------------------------------------------------------------------+
| XmText Output Resource Set |
| Name Class Type Default Access |
| XmNblinkRate XmCBlinkRate int 500 CSG |
| XmNcolumns XmCColumns short dynamic CSG |
| XmNcursorPositionVisible XmCCursorPositionVisible Boolean True CSG |
| XmNfontList XmCFontList XmFontList dynamic CSG |

| XmNresizeWidth XmCResizeWidth Boolean False CSG |
| XmNrows XmCRows short dynamic CSG |
| XmNwordWrap XmCWordWrap Boolean False CSG |
+----------------------------------------------------------------------------------------+

XmNblinkRate
Specifies the blink rate of the text cursor in milliseconds.
The time indicated in the blink rate relates to the time the
cursor is visible and the time the cursor is invisible (that
is, the time it takes to blink the insertion cursor on and
off is twice the blink rate). The cursor does not blink when
the blink rate is set to 0 (zero). The value must not be
negative.

XmNcolumns
Specifies the initial width of the text window as an integer
number of characters. The width equals the number of charac-
ters specified by this resource multiplied by the width as
derived from the specified font. If the em-space value is
available, it is used. If not, the width of the numeral "0"
is used. If this is not available, the maximum width is used.
For proportionate fonts, the actual number of characters that
fit on a given line may be greater than the value specified.
The value must be greater than 0 (zero). The default value
depends on the value of the XmNwidth resource. If no width
is specified the default is 20.

When the XmNlayoutDirection resource is XmTOP_TO_BOTTOM, and
if the XmText widget resource XmNeditMode is XmSIN-
GLE_LINE_EDIT, this attribute is ignored. If no width is
specified, the default is 1.

XmNcursorPositionVisible
Indicates that the insert cursor position is marked by a text
cursor when the Boolean value is True.

XmNfontList
Specifies the font list to be used for Text. The font list is
an obsolete structure and is retained only for compatibility
with earlier releases of Motif. Use the render table (XmNren-
derTable) instead of font lists wherever possible. If both
are specified, the render table will take precedence. If this
value is NULL at initialization, the parent hierarchy of the
widget is searched for an ancestor that holds the XmQTspeci-
fyRenderTable trait. If such an ancestor is found, the font
list is initialized to the XmTEXT_RENDER_TABLE value of the
ancestor widget. If no such ancestor is found, the default is
implementation dependent.

Text searches the font list for the first occurrence of a
font set that has XmFONTLIST_DEFAULT_TAG. If a default ele-
ment is not found, the first font set in the font list is
used. If the list contains no font sets, the first font in
the font list will be used. Refer to XmFontList(3) for more
information on a font list structure.

XmNrenderTable
Specifies the render table to be used in deriving a font set
or font for rendering text. If both a render table and a font
list are specified, the render table will take precedence. If
the value of XmNrenderTable is NULL at initialization, the
parent hierarchy of the widget is searched for an ancestor
that holds the XmQTspecifyRenderTable trait. If such an an-
cestor is found, the font list is initialized to the Xm-
TEXT_RENDER_TABLE value of the ancestor widget. If no such
ancestor is found, the default is implementation dependent.

Text searches the render table for the first occurrence of a
rendition that has the tag _MOTIF_DEFAULT_LOCALE. If a de-
fault element is not found, the first rendition in the table
is used. Refer to XmRenderTable(3) for more information on
the render table structure.

XmNresizeHeight
Indicates that Text will attempt to resize its height to ac-
commodate all the text contained in the widget when the
Boolean value is True. If the Boolean value is set to True,
the text is always displayed, starting from the first posi-
tion in the source, even if instructed otherwise. This at-
tribute is ignored when the application uses a Text widget
whose parent is a ScrolledWindow and when XmNscrollVertical
is True.

When the XmNlayoutDirection resource is XmTOP_TO_BOTTOM, this
resource indicates that the text attempts to resize its
height to accommodate all the text contained in the widget
when the Boolean value is True. This attribute is ignored if
XmNwordWrap is True.

XmNresizeWidth
Indicates that Text attempts to resize its width to accommo-
date all the text contained in the widget when the Boolean
value is True. This attribute is ignored if XmNwordWrap is
True.

When the XmNlayoutDirection resource is XmTOP_TO_BOTTOM, this
attribute is still effective even if XmNwordWrap is True.
Also, this attribute is ignored when the application uses a
text widget whose parent is a ScrolledWindow and XmNscroll-
Horizaontal is True.

XmNrows Specifies the initial height of the text window measured in
character heights. This attribute is ignored if the text wid-
get resource XmNeditMode is XmSINGLE_LINE_EDIT. The value
must be greater than 0 (zero). The default value depends on
the value of the XmNheight resource. If no height is speci-
fied, the default is 1.

When the XmNlayoutDirection resource is XmTOP_TO_BOTTOM, this
attribute is still effective, even if the XmText widget re-
source XmNeditMode is XmSINGLE_LINE_EDIT. If no height is
specified, the default is 20.

XmNwordWrap
Indicates that lines are to be broken at word breaks (that
is, the text does not go off the right edge of the window)
when the Boolean value is True. Words are defined as a se-
quence of characters separated by whitespace. Whitespace is
defined as a space, tab, or newline. This attribute is ig-
nored if the text widget resource XmNeditMode is XmSIN-
GLE_LINE_EDIT. Note that this resource is only valid when
the widget is not a scroll one, or, if the widget is a scroll
widget, that the XmNscrollHorizontal resource is False.

Indicates that lines are to be broken at word breaks (that
is, when the XmNlayoutDirection resource is XmTOP_TO_BOTTOM,
the text does not go off the bottom edge of the window) when
the Boolean value is True.

The following resources are used only when text is created in a
ScrolledWindow. See the reference page for XmCreateScrolledText.
+------------------------------------------------------------------+
| XmText Scrolling Resource Set |
| Name Class Type Default Access |
| XmNscrollHorizontal XmCScroll Boolean True CG |
| XmNscrollLeftSide XmCScrollSide Boolean False CG |
| XmNscrollTopSide XmCScrollSide Boolean False CG |
| XmNscrollVertical XmCScroll Boolean True CG |
+------------------------------------------------------------------+

Note in connection with this table that if the XmNlayoutDirection re-
source is XmTOP_TO_BOTTOM, the default is True.

XmNscrollHorizontal
Adds a ScrollBar that allows the user to scroll horizontally
through text when the Boolean value is True. This resource
is forced to False when the Text widget is placed in a
ScrolledWindow with XmNscrollingPolicy set to XmAUTOMATIC.

When the XmNlayoutDirection resource is XmTOP_TO_BOTTOM, this
attribute is ignored if the XmText widget resource XmNedit-
Mode is XmSINGLE_LINE_EDIT.

XmNscrollLeftSide
Indicates that the vertical ScrollBar should be placed on the
left side of the scrolled text window when the Boolean value
is True. This attribute is ignored if XmNscrollVertical is
False or the Text resource XmNeditMode is XmSINGLE_LINE_EDIT.

When the XmNlayoutDirection resource is XmTOP_TO_BOTTOM, this
resource is still effective, even if the XmText widget re-
source XmNeditMode is XmSINGLE_LINE_EDIT.

XmNscrollTopSide
Indicates that the horizontal ScrollBar should be placed on
the top side of the scrolled text window when the Boolean
value is True.

When the XmNlayoutDirection resource is XmTOP_TO_BOTTOM, this
attribute is ignored if XmNscrollHorizontal is False or the
Xmtext resource XmNeditMode is XmSINGLE_LINE_EDIT.

XmNscrollVertical
Adds a ScrollBar that allows the user to scroll vertically
through text when the Boolean value is True. This attribute
is ignored if the Text resource XmNeditMode is XmSIN-
GLE_LINE_EDIT. This resource is forced to False when the
Text widget is placed in a ScrolledWindow with XmNscrolling-
Policy set to XmAUTOMATIC.

When the XmNlayoutDirection resource is XmTOP_TO_BOTTOM, this
resource is still effective, even if the XmText widget re-
source XmNeditMode is XmSINGLE_LINE_EDIT.

Inherited Resources
Text inherits behavior and resources from the superclasses described in
the following tables. For a complete description of each resource, re-
fer to the reference page for that superclass.

Callback Information
A pointer to the following structure is passed to each callback:

typedef struct
{
int reason;
XEvent * event;
} XmAnyCallbackStruct;

reason Indicates why the callback was invoked

event Points to the XEvent that triggered the callback

The Text widget defines a new callback structure for use with verifica-
tion callbacks. Note that not all fields are relevant for every call-
back reason. The application must first look at the reason field and
use only the structure members that are valid for the particular rea-
son. The values startPos, endPos, and text in the callback structure
XmTextVerifyCallbackStruct may be modified when the callback is re-
ceived, and these changes will be reflected as changes made to the
source of the Text widget. (For example, all keystrokes can be con-
verted to spaces or NULL characters when a password is entered into a
Text widget.) The application programmer should not overwrite the text
field, but should attach data to that pointer.

A pointer to the following structure is passed to callbacks for XmNlos-
ingFocusCallback, XmNmodifyVerifyCallback, and XmNmotionVerifyCallback:

typedef struct
{
int reason;
XEvent * event;
Boolean doit;
XmTextPosition currInsert, newInsert;
XmTextPosition startPos, endPos;
XmTextBlock text;
} XmTextVerifyCallbackStruct, *XmTextVerifyPtr;

reason Indicates why the callback was invoked.

event Points to the XEvent that triggered the callback. It can be
NULL. For example, changes made to the Text widget program-
matically do not have an event that can be passed to the as-
sociated callback.

doit Indicates whether the action that invoked the callback is
performed. Setting doit to False negates the action. Note
that not all actions may be negated. For example, XmCR_LOS-
ING_FOCUS callbacks may be beyond the control of the widget
if they are produced by mouse clicks.

currInsert
Indicates the current position of the insert cursor.

newInsert Indicates the position at which the user attempts to position
the insert cursor.

startPos Indicates the starting position of the text to modify. If the
callback is not a modify verification callback, this value is
the same as currInsert.

endPos Indicates the ending position of the text to modify. If no
text is replaced or deleted, the value is the same as start-
Pos. If the callback is not a modify verification callback,
this value is the same as currInsert.

text Points to a structure of type XmTextBlockRec. This structure
holds the textual information to be inserted.

typedef struct
{
char *ptr;
int length;
XmTextFormat format;
} XmTextBlockRec, *XmTextBlock;

ptr Points to the text to be inserted.

length Specifies the length of the text to be inserted.

format Specifies the format of the text, either XmFMT_8_BIT
or XmFMT_16_BIT.

A pointer to the following structure is passed to callbacks for XmNmod-
ifyVerifyCallbackWcs.

typedef struct
{
int reason;
XEvent *event;
Boolean doit;
XmTextPosition currInsert, newInsert;
XmTextPosition startPos, endPos;
XmTextBlockWcs text;
} XmTextVerifyCallbackStructWcs, *XmTextVerifyPtrWcs;

reason Indicates why the callback was invoked.

currInsert
Indicates the current position of the insert cursor.

newInsert Indicates the position at which the user attempts to position
the insert cursor.

startPos Indicates the starting position of the text to modify. If the
callback is not a modify verification callback, this value is
the same as currInsert.

text Points to the following structure of type XmTextBlockRecWcs.
This structure holds the textual information to be inserted.

typedef struct
{
wchar_t *wcsptr;
int length;
} XmTextBlockRecWcs, *XmTextBlockWcs;

wcsptr Points to the wide character text to be inserted.

length Specifies the number of characters to be inserted.

The following table describes the reasons for which the individual ver-
ification callback structure fields are valid. Note that the event
field will never be valid for XmCR_MOVING_INSERT_CURSOR.
+-----------------------------------------------------------------+
| Reason Valid Fields |
| XmCR_LOSING_FOCUS reason, event, doit, currInsert, |
| newInsert, startPos, endPos |
| XmCR_MODIFYING_TEXT_VALUE reason, event, doit, currInsert, |
| newInsert, startPos, endPos, text |
| XmCR_MOVING_INSERT_CURSOR reason, doit, currInsert, newInsert |
+-----------------------------------------------------------------+

A pointer to the following callback structure is passed to the XmNdes-
tinationCallback procedures:

typedef struct
{
int reason;
XEvent *event;
Atom selection;
XtEnum operation;
int flags;
XtPointer transfer_id;
XtPointer destination_data;
XtPointer location_data;
Time time;
} XmDestinationCallbackStruct;

reason Indicates why the callback was invoked.

event Points to the XEvent that triggered the callback. It can be
NULL.

selection Indicates the selection for which data transfer is being re-
quested. Possible values are CLIPBOARD, PRIMARY, SECONDARY,
and _MOTIF_DROP.

operation Indicates the type of transfer operation requested.

• When the selection is PRIMARY or SECONDARY, possible
values are XmMOVE, XmCOPY, and XmLINK.

• When the selection is CLIPBOARD, possible values are
XmCOPY and XmLINK.

• When the selection is _MOTIF_DROP, possible values are
XmMOVE, XmCOPY, XmLINK, and XmOTHER. A value of
XmOTHER means that the callback procedure must get fur-
ther information from the XmDropProcCallbackStruct
structure in the destination_data member.

flags Indicates whether or not the destination widget is also the
source of the data to be transferred. Following are the pos-
sible values:

XmCONVERTING_NONE
The destination widget is not the source of the
data to be transferred.

XmCONVERTING_SAME
The destination widget is the source of the data to
be transferred.

transfer_id
Serves as a unique ID to identify the transfer transaction.

destination_data
Contains information about the destination. When the selec-
tion is _MOTIF_DROP, the callback procedures are called by
the drop site's XmNdropProc, and destination_data is a
pointer to the XmDropProcCallbackStruct structure passed to
the XmNdropProc procedure. When the selection is SECONDARY,
destination_data is an Atom representing a target recomm-
mended by the selection owner for use in converting the se-
lection. Otherwise, destination_data is NULL.

location_data
Contains information about the location where data is to be
transferred. The value is always NULL when the selection is
CLIPBOARD. If the value is NULL, the data is to be inserted
at the widget's cursor position. Otherwise, the value is a
pointer to an XPoint structure containing the x- and y- coor-
dinates at the location where the data is to be transferred.
Once XmTransferDone procedures start to be called, loca-
tion_data will no longer be stable.

time Indicates the time when the transfer operation began.

Translations
The XmText translations are described in the following list. The ac-
tions represent the effective behavior of the associated events, and
they may differ in a right-to-left language environment.

The following key names are listed in the X standard key event transla-
tion table syntax. This format is the one used by Motif to specify the
widget actions corresponding to a given key. A brief overview of the
format is provided under VirtualBindings(3). For a complete descrip-
tion of the format, please refer to the X Toolkit Instrinsics Documen-
tation.

The Text button event translations are modified when Display's XmNen-
ableBtn1Transfer resource does not have a value of XmOFF (in other
words, it is either XmBUTTON2_TRANSFER or XmBUTTON2_ADJUST). This op-
tion allows the actions for selection and transfer to be integrated on
<Btn1>, and the actions for extending the selection can be bound to
<Btn2>. The actions for <Btn1> that are defined above still apply when
the <Btn1> event occurs over text that is not selected. The following
actions apply when the <Btn1> event occurs over text that is selected:

<Btn1Down>:
process-bdrag().

<Shift><Btn1Down>:
process-bdrag().

<Ctrl><Btn1Down>:
process-bdrag().

<Btn1Down><Shift><Btn1Up>:
grab-focus(), extend-end.

<Shift><Btn1Down><Shift><Btn1Up>:
extend-start(), extend-end().

<Ctrl><Btn1Down><Shift><Btn1Up>:
move-destination().

When Display's XmNenableBtn1Transfer resource has a value of XmBUT-
TON2_ADJUST, the following actions apply:

<Btn2Down>:
extend-start().

<Btn2Motion>:
extend-adjust().

<Btn2Up>: extend-end().

Action Routines
The XmText action routines are

activate():
Calls the callbacks for XmNactivateCallback. Passes the
event to the parent.

backward-character(extend):
Moves the insertion cursor one character to the left. This
action may have different behavior in a right-to-left lan-
guage environment.

If called with an argument of extend, moves the insertion
cursor as in the case of no argument and extends the current
selection.

The backward-character() action produces calls to the XmNmo-
tionVerifyCallback procedures with reason value XmCR_MOV-
ING_INSERT_CURSOR. If called with the extend argument, the
backward-character() action may produce calls to the XmNgain-
PrimaryCallback procedures. See callback description for
more information.

In vertical writing, if XmNeditMode is XmSINGLE_LINE_EDIT and
XmNnavigationType is XmNONE, traverses to the widget to the
left in the tab group. If XmNeditMode is XmMULTI_LINE_EDIT,
moves the insertion cursor to the next line in the same col-
umn.

backward-paragraph(extend):
If XmNeditMode is XmMULTI_LINE_EDIT and this action is called
with no argument, moves the insertion cursor to the first
non-whitespace character following the first previous blank
line or beginning of the text. If the insertion cursor is
already at the beginning of a paragraph, moves the insertion
cursor to the beginning of the previous paragraph.

If XmNeditMode is XmMULTI_LINE_EDIT and this action is called
with an argument of extend, moves the insertion cursor as in
the case of no argument and extends the current selection.

The backward-paragraph() action produces calls to the XmNmo-
tionVerifyCallback procedures with reason value XmCR_MOV-
ING_INSERT_CURSOR. If called with the extend argument, the
backward-paragraph() action may produce calls to the XmNgain-
PrimaryCallback procedures. See callback description for
more information.

backward-word(extend):
If this action is called with no argument, moves the inser-
tion cursor to the first non-whitespace character after the
first whitespace character to the left or after the beginning
of the line. If the insertion cursor is already at the be-
ginning of a word, moves the insertion cursor to the begin-
ning of the previous word. This action may have different
behavior in a locale other than the C locale.

If called with an argument of extend, moves the insertion
cursor as in the case of no argument and extends the current
selection.

The backward-word() action produces calls to the XmNmotion-
VerifyCallback procedures with reason value XmCR_MOVING_IN-
SERT_CURSOR. If called with the extend argument, the back-
ward-word() action may produce calls to the XmNgainPrima-
ryCallback procedures. See callback description for more in-
formation.

beep(): Causes the terminal to beep. The beep() action produces no
callbacks.

beginning-of-file(extend):
If this action is called with no argument, moves the inser-
tion cursor to the beginning of the text.

If called with an argument of extend, moves the insertion
cursor as in the case of no argument and extends the current
selection.

The beginning-of-file() action produces calls to the XmNmo-
tionVerifyCallback procedures with reason value XmCR_MOV-
ING_INSERT_CURSOR. If called with the extend argument, the
beginning-of-file() action may produce calls to the XmNgain-
PrimaryCallback procedures. See callback description for
more information.

beginning-of-line(extend):
If this action is called with no argument, moves the inser-
tion cursor to the beginning of the line.

If called with an argument of extend, moves the insertion
cursor as in the case of no argument and extends the current
selection.

The beginning-of-line() action produces calls to the XmNmo-
tionVerifyCallback procedures with reason value XmCR_MOV-
ING_INSERT_CURSOR. If called with the extend argument, the
beginning-of-line() action may produce calls to the XmNgain-
PrimaryCallback procedures. See callback description for
more information.

clear-selection():
Clears the current selection by replacing each character ex-
cept <Return> with a <space> character.

The clear-selection() action produces calls to the XmNmodi-
fyVerifyCallback procedures with reason value XmCR_MODIFY-
ING_TEXT_VALUE and the XmNvalueChangedCallback procedures
with reason value XmCR_VALUE_CHANGED.

copy-clipboard():
If this widget owns the primary selection, this action copies
the selection to the clipboard. This action calls the XmN-
convertCallback procedures, possibly multiple times, for the
CLIPBOARD selection.

copy-primary():
Copies the primary selection to just before the insertion
cursor. This action calls the XmNdestinationCallback proce-
dures for the PRIMARY selection and the XmCOPY operation. It
calls the selection owner's XmNconvertCallback procedures,
possibly multiple times, for the PRIMARY selection.

In addition, the copy-primary() action produces calls to the
XmNmodifyVerifyCallback procedures with reason value
XmCR_MODIFYING_TEXT_VALUE, to the XmNvalueChangedCallback
procedures with reason value XmCR_VALUE_CHANGED, and to the
XmNmotionVerifyCallback procedures with reason value
XmCR_MOVING_INSERT_CURSOR.

copy-to():
If a secondary selection exists, this action copies the sec-
ondary selection to the insertion position of the destination
component. If the primary selection is in the destination
widget, it will be deselected. Otherwise, there is no effect
on the primary selection.

This action calls the destination's XmNdestinationCallback
procedures for the SECONDARY selection and the XmCOPY opera-
tion. The destination's XmNdestinationCallback procedures or
the destination component itself invokes the selection
owner's XmNconvertCallback procedures, possibly multiple
times, for the SECONDARY selection.

If no secondary selection exists, this action copies the pri-
mary selection to the pointer position. This action calls
the XmNdestinationCallback procedures for the PRIMARY selec-
tion and the XmCOPY operation. It calls the selection
owner's XmNconvertCallback procedures, possibly multiple
times, for the PRIMARY selection.

In addition, the copy-to() action produces calls to the XmN-
modifyVerifyCallback procedures with reason value XmCR_MODI-
FYING_TEXT_VALUE, to the XmNvalueChangedCallback procedures
with reason value XmCR_VALUE_CHANGED, and to the XmNmotion-
VerifyCallback procedures with reason value XmCR_MOVING_IN-
SERT_CURSOR. If there is no secondary selection, the copy-
to() action may produce calls to the XmNgainPrimaryCallback
procedures. See callback description for more information.

cut-clipboard():
If this widget owns the primary selection, this action cuts
the selection to the clipboard. This action calls the XmN-
convertCallback procedures, possibly multiple times, for the
CLIPBOARD selection. If the transfer is successful, this ac-
tion then calls the XmNconvertCallback procedures for the
CLIPBOARD selection and the DELETE target.

In addition, the cut-clipboard() action produces calls to the
XmNmodifyVerifyCallback procedures with reason value
XmCR_MODIFYING_TEXT_VALUE, and the XmNvalueChangedCallback
procedures with reason value XmCR_VALUE_CHANGED.

cut-primary():
Cuts the primary selection and pastes it just before the in-
sertion cursor. This action calls the XmNdestinationCallback
procedures for the PRIMARY selection and the XmMOVE opera-
tion. It calls the selection owner's XmNconvertCallback pro-
cedures, possibly multiple times, for the PRIMARY selection.
If the transfer is successful, this action then calls the se-
lection owner's XmNconvertCallback procedures for the PRIMARY
selection and the DELETE target. The cut-primary() action
may produce calls to the XmNgainPrimaryCallback procedures.
See callback description for more information.

In addition, the cut-primary() action produces calls to the
XmNmotionVerifyCallback procedures with reason value
XmCR_MOVING_INSERT_CURSOR, the XmNmodifyVerifyCallback proce-
dures with reason value XmCR_MODIFYING_TEXT_VALUE, and the
XmNvalueChangedCallback procedures with reason value
XmCR_VALUE_CHANGED.

delete-next-character():
In normal mode, if there is a nonnull selection, deletes the
selection; otherwise, deletes the character following the in-
sertion cursor. In add mode, if there is a nonnull selec-
tion, the cursor is not disjoint from the selection, and XmN-
pendingDelete is set to True, deletes the selection; other-
wise, deletes the character following the insertion cursor.
This may impact the selection.

The delete-next-character() action produces calls to the XmN-
modifyVerifyCallback procedures with reason value XmCR_MODI-
FYING_TEXT_VALUE, and the XmNvalueChangedCallback procedures
with reason value XmCR_VALUE_CHANGED.

delete-next-word():
In normal mode, if there is a nonnull selection, deletes the
selection; otherwise, deletes the characters following the
insertion cursor to the next space, tab or end-of-line char-
acter. In add mode, if there is a nonnull selection, the
cursor is not disjoint from the selection, and XmNpend-
ingDelete is set to True, deletes the selection; otherwise,
deletes the characters following the insertion cursor to the
next space, tab or end-of-line character. This may impact
the selection. This action may have different behavior in a
locale other than the C locale.

The delete-next-word() action produces calls to the XmNmodi-
fyVerifyCallback procedures with reason value XmCR_MODIFY-
ING_TEXT_VALUE, and the XmNvalueChangedCallback procedures
with reason value XmCR_VALUE_CHANGED.

delete-previous-character():
In normal mode, if there is a nonnull selection, deletes the
selection; otherwise, deletes the character of text immedi-
ately preceding the insertion cursor. In add mode, if there
is a nonnull selection, the cursor is not disjoint from the
selection, and XmNpendingDelete is set to True, deletes the
selection; otherwise, deletes the character of text immedi-
ately preceding the insertion cursor. This may impact the
selection.

The delete-previous-character() action produces calls to the
XmNmodifyVerifyCallback procedures with reason value
XmCR_MODIFYING_TEXT_VALUE, the XmNvalueChangedCallback proce-
dures with reason value XmCR_VALUE_CHANGED, and the XmNmo-
tionVerifyCallback procedures with reason value XmCR_MOV-
ING_INSERT_CURSOR.

delete-previous-word():
In normal mode, if there is a nonnull selection, deletes the
selection; otherwise, deletes the characters preceding the
insertion cursor to the next space, tab or beginning-of-line
character. In add mode, if there is a nonnull selection, the
cursor is not disjoint from the selection, and XmNpend-
ingDelete is set to True, deletes the selection; otherwise,
deletes the characters preceding the insertion cursor to the
next space, tab or beginning-of-line character. This may im-
pact the selection. This action may have different behavior
in a locale other than the C locale.

The delete-previous-word() action produces calls to the XmN-
modifyVerifyCallback procedures with reason value XmCR_MODI-
FYING_TEXT_VALUE, the XmNvalueChangedCallback procedures with
reason value XmCR_VALUE_CHANGED, and the XmNmotionVerifyCall-
back procedures with reason value XmCR_MOVING_INSERT_CURSOR.

delete-selection():
Deletes the current selection.

The delete-selection() action produces calls to the XmNmodi-
fyVerifyCallback procedures with reason value XmCR_MODIFY-
ING_TEXT_VALUE, the XmNvalueChangedCallback procedures with
reason value XmCR_VALUE_CHANGED, and the XmNmotionVerifyCall-
back procedures with reason value XmCR_MOVING_INSERT_CURSOR.

delete-to-end-of-line():
In normal mode, if there is a nonnull selection, deletes the
selection; otherwise, deletes the characters following the
insertion cursor to the next end of line character. In add
mode, if there is a nonnull selection, the cursor is not dis-
joint from the selection, and XmNpendingDelete is set to
True, deletes the selection; otherwise, deletes the charac-
ters following the insertion cursor to the next end of line
character. This may impact the selection.

The delete-to-end-of-line() action produces calls to the XmN-
modifyVerifyCallback procedures with reason value XmCR_MODI-
FYING_TEXT_VALUE, and the XmNvalueChangedCallback procedures
with reason value XmCR_VALUE_CHANGED.

delete-to-start-of-line():
In normal mode, if there is a nonnull selection, deletes the
selection; otherwise, deletes the characters preceding the
insertion cursor to the previous beginning-of-line character.
In add mode, if there is a nonnull selection, the cursor is
not disjoint from the selection, and XmNpendingDelete is set
to True, deletes the selection; otherwise, deletes the char-
acters preceding the insertion cursor to the previous begin-
ning-of-line character. This may impact the selection.

The delete-to-start-of-line() action produces calls to the
XmNmodifyVerifyCallback procedures with reason value
XmCR_MODIFYING_TEXT_VALUE, the XmNvalueChangedCallback proce-
dures with reason value XmCR_VALUE_CHANGED, and the XmNmo-
tionVerifyCallback procedures with reason value XmCR_MOV-
ING_INSERT_CURSOR.

deselect-all():
Deselects the current selection. The deselect-all() action
produces no callbacks.

end-of-file(extend):
If this action is called with no argument, moves the inser-
tion cursor to the end of the text.

If called with an argument of extend, moves the insertion
cursor as in the case of no argument and extends the current
selection.

The end-of-file() action produces calls to the XmNmotionVeri-
fyCallback procedures with reason value XmCR_MOVING_IN-
SERT_CURSOR. If called with the extend argument, the end-of-
file() action may produce calls to the XmNgainPrimaryCallback
procedures. See callback description for more information.

end-of-line(extend):
If this action is called with no argument, moves the inser-
tion cursor to the end of the line. If called with an argu-
ment of extend, moves the insertion cursor as in the case of
no argument and extends the current selection.

The end-of-line() action produces calls to the XmNmotionVeri-
fyCallback procedures with reason value XmCR_MOVING_IN-
SERT_CURSOR. If called with the extend argument, the end-of-
line() action may produce calls to the XmNgainPrimaryCallback
procedures. See callback description for more information.

extend-adjust():
Selects text from the anchor to the pointer position and des-
elects text outside that range. Moving the pointer over sev-
eral lines selects text from the anchor to the end of each
line the pointer moves over and up to the pointer position on
the current line.

The extend-adjust() action produces calls to the XmNmotion-
VerifyCallback procedures with reason value XmCR_MOVING_IN-
SERT_CURSOR. The extend-adjust() action may produce calls to
the XmNgainPrimaryCallback procedures. See callback descrip-
tion for more information.

extend-end():
Moves the insertion cursor to the position of the pointer.
The extend-end() action is used to commit the selection. Af-
ter this action has been done, process-cancel() will no
longer cancel the selection.

The extend-end() action produces calls to the XmNmotionVeri-
fyCallback procedures with reason value XmCR_MOVING_IN-
SERT_CURSOR. The extend-end() action may produce calls to
the XmNgainPrimaryCallback procedures. See callback descrip-
tion for more information.

extend-start():
Adjusts the anchor using the balance-beam method. Selects
text from the anchor to the pointer position and deselects
text outside that range. The extend-start() action may pro-
duce no callbacks, however, the extend-start() action may
produce calls to the XmNgainPrimaryCallback procedures. See
callback description for more information.

forward-character(extend):
Moves the insertion cursor one character to the right. This
action may have different behavior in a right-to-left lan-
guage environment.

If called with an argument of extend, moves the insertion
cursor as in the case of no argument and extends the current
selection.

The forward-character() action produces calls to the XmNmo-
tionVerifyCallback procedures with reason value XmCR_MOV-
ING_INSERT_CURSOR. If called with the extend argument, the
forward-character() action may produce calls to the XmNgain-
PrimaryCallback procedures. See callback description for
more information.

In vertical writing, if XmNeditMode is XmSINGLE_LINE_EDIT and
XmNnavigationType is XmNONE, traverses to the widget to the
right in the tab group. If XmNeditMode is XmMULTI_LINE_EDIT,
moves the insertion cursor to the previous line in the same
column.

forward-paragraph(extend):
If XmNeditMode is XmMULTI_LINE_EDIT, and this action is
called with no argument, moves the insertion cursor to the
first non-whitespace character following the next blank line.
If the insertion cursor is already at the beginning of a
paragraph, moves the insertion cursor to the beginning of the
next paragraph.

If XmNeditMode is XmMULTI_LINE_EDIT and this action is called
with an argument of extend, moves the insertion cursor as in
the case of no argument and extends the current selection.

The forward-paragraph() action produces calls to the XmNmo-
tionVerifyCallback procedures with reason value XmCR_MOV-
ING_INSERT_CURSOR. If called with the extend argument, the
forward-paragraph() action may produce calls to the XmNgain-
PrimaryCallback procedures. See callback description for
more information.

forward-word(extend):
If this action is called with no argument, moves the inser-
tion cursor to the first whitespace character or end-of-line
following the next non-whitespace character. If the inser-
tion cursor is already at the end of a word, moves the inser-
tion cursor to the end of the next word. This action may
have different behavior in a locale other than the C locale.

If called with an argument of extend, moves the insertion
cursor as in the case of no argument and extends the current
selection.

The forward-word() action produces calls to the XmNmotionVer-
ifyCallback procedures with reason value XmCR_MOVING_IN-
SERT_CURSOR. If called with the extend argument, the for-
ward-word() action may produce calls to the XmNgainPrima-
ryCallback procedures. See callback description for more in-
formation.

grab-focus():
This key binding performs the action defined in the XmNselec-
tionArray, depending on the number of multiple mouse clicks.
The default selection array ordering is one click to move the
insertion cursor to the pointer position, two clicks to se-
lect a word, three clicks to select a line of text, and four
clicks to select all text. A single click also deselects any
selected text and sets the anchor at the pointer position.
This action may have different behavior in a locale other
than the C locale.

The grab-focus() action produces calls to the XmNmotionVeri-
fyCallback procedures with reason value XmCR_MOVING_IN-
SERT_CURSOR.

Help(): Calls the callbacks for XmNhelpCallback if any exist. If
there are no help callbacks for this widget, this action
calls the help callbacks for the nearest ancestor that has
them.

insert-string(string):
If XmNpendingDelete is True and the cursor is not disjoint
from the current selection, deletes the entire selection.
Inserts string before the insertion cursor.

The insert-string() action produces calls to the XmNmodi-
fyVerifyCallback procedures with reason value XmCR_MODIFY-
ING_TEXT_VALUE, the XmNvalueChangedCallback procedures with
reason value XmCR_VALUE_CHANGED, and the XmNmotionVerifyCall-
back procedures with reason value XmCR_MOVING_INSERT_CURSOR.
Note that, in the case of an empty string, no callbacks will
be called, since no modification will have been done. How-
ever, if the insertion position is inside the current selec-
tion, insert-string with an empty string will cause the se-
lection to be deselected, and the XmNmotionVerifyCallback
procedures to be called with reason value XmCR_MOVING_IN-
SERT_CURSOR, XmCR_MODIFYING_TEXT_VALUE, and
XmCR_VALUE_CHANGED.

key-select(right|left):
If called with an argument of right, moves the insertion cur-
sor one character to the right and extends the current selec-
tion. If called with an argument of left, moves the inser-
tion cursor one character to the left and extends the current
selection. If called with no argument, extends the current
selection.

Note that after a key-select action, the selection will still
begin at the original anchor, and will extend to the position
indicated in the action call. If this new position is on the
opposite side of the selection anchor from the previous se-
lection boundary, the original selection will be deselected.

The key-select() action produces calls to the XmNmotionVeri-
fyCallback procedures with reason value XmCR_MOVING_IN-
SERT_CURSOR. The key-select() action may produce calls to
the XmNgainPrimaryCallback procedures. See callback descrip-
tion for more information.

In vertical writing, if called with the argument left, and if
XmNeditMode is XmMULTI_LINE_EDIT, moves the insertion cursor
to the next line in the same column. In vertical writing, if
called with the argument right, and if XmNeditMode is Xm-
MULTI_LINE_EDIT, moves the insertion cursor to the previous
line in the same column.)

selection; otherwise, kills the character following the in-
sertion cursor and stores the character in the cut buffer.
In add mode, if there is a nonnull selection, the cursor is
not disjoint from the selection, and XmNpendingDelete is set
to True, deletes the selection; otherwise, kills the charac-
ter following the insertion cursor and stores the character
in the cut buffer. This may impact the selection.

character, and stores the characters in the cut buffer. In
add mode, if there is a nonnull selection, the cursor is not
disjoint from the selection, and XmNpendingDelete is set to
True, deletes the selection; otherwise, kills the characters
preceding the insertion cursor up to the next space, tab or
beginning-of-line character, and stores the characters in the
cut buffer. This may impact the selection. This action may
have different behavior in a locale other than the C locale.

The killed text is stored in CUT_BUFFER0.

The kill-previous-word() action produces calls to the XmNmod-
ifyVerifyCallback procedures with reason value XmCR_MODIFY-
ING_TEXT_VALUE, the XmNvalueChangedCallback procedures with
reason value XmCR_VALUE_CHANGED, and the XmNmotionVerifyCall-
back procedures with reason value XmCR_MOVING_INSERT_CURSOR.

kill-selection():

link-primary():
Places a link to the primary selection just before the inser-
tion cursor. This action calls the XmNdestinationCallback
procedures for the PRIMARY selection and the XmLINK opera-
tion. The Text widget itself performs no transfers; the XmN-
destinationCallback procedures are responsible for inserting
the link to the primary selection and for taking any related
actions.

link-to():
If a secondary selection exists, this action places a link to
the secondary selection at the insertion position of the des-
tination component. This action calls the destination's XmN-
destinationCallback procedures for the SECONDARY selection
and the XmLINK operation.

If no secondary selection exists, this action places a link
to the primary selection at the pointer position. This ac-
tion calls the XmNdestinationCallback procedures for the PRI-
MARY selection and the XmLINK operation.

The Text widget itself performs no transfers; the XmNdestina-
tionCallback procedures are responsible for inserting the
link to the primary or secondary selection and for taking any
related actions.

move-destination():
Moves the insertion cursor to the pointer position without
changing any existing current selection. If there is a cur-
rent selection, sets the widget as the destination widget.
This also moves the widget focus to match the insertion cur-
sor.

The move-destination() action produces calls to the XmNmo-
tionVerifyCallback procedures with reason value XmCR_MOV-
ING_INSERT_CURSOR.

move-to():
If a secondary selection exists, this action moves the sec-
ondary selection to the insertion position of the destination
component. If the secondary selection is in the destination
widget, and the secondary selection and the primary selection
overlap, the result is undefined. This action calls the des-
tination's XmNdestinationCallback procedures for the SEC-
ONDARY selection and the XmMOVE operation. The destination's
XmNdestinationCallback procedures or the destination compo-
nent itself invokes the selection owner's XmNconvertCallback
procedures, possibly multiple times, for the SECONDARY selec-
tion. If the transfer is successful, this action then calls
the selection owner's XmNconvertCallback procedures for the
SECONDARY selection and the DELETE target.

If no secondary selection exists, this action moves the pri-
mary selection to the pointer position. This action calls
the XmNdestinationCallback procedures for the PRIMARY selec-
tion and the XmMOVE operation. It calls the selection
owner's XmNconvertCallback procedures, possibly multiple
times, for the PRIMARY selection. If the transfer is suc-
cessful, this action then calls the selection owner's XmNcon-
vertCallback procedures for the PRIMARY selection and the
DELETE target.

The move-to() action produces calls to the XmNmodifyVerify-
Callback procedures with reason value XmCR_MODIFY-
ING_TEXT_VALUE, the XmNvalueChangedCallback procedures with
reason value XmCR_VALUE_CHANGED, and the XmNmotionVerifyCall-
back procedures with reason value XmCR_MOVING_INSERT_CURSOR.

sitions the insertion cursor to the end of the line before
the newline.

The newline-and-backup() action produces calls to the XmNmod-
ifyVerifyCallback procedures with reason value XmCR_MODIFY-
ING_TEXT_VALUE, and the XmNvalueChangedCallback procedures

results in the widget losing focus, in which case, the XmN-
losingFocusCallback procedures are called with reason value
XmCR_LOSING_FOCUS.

page-left(extend):
If XmNeditMode is XmMULTI_LINE_EDIT and this action is called
with no argument, moves the insertion cursor back one page.

If XmNeditMode is XmMULTI_LINE_EDIT and this action is called
with an argument of extend, it moves the insertion cursor as
in the case of no argument and extends the current selection.

The page-left() action produces calls to the XmNmotionVerify-
Callback procedures with reason value XmCR_MOVING_INSERT_CUR-
SOR. If called with the extend argument, the page-left() ac-
tion may produce calls to the XmNgainPrimaryCallback proce-
dures. See callback description for more information.

page-right(extend):
If XmNeditMode is XmMULTI_LINE_EDIT and this action is called

VerifyCallback procedures with reason value XmCR_MOVING_IN-
SERT_CURSOR. If called with the extend argument, the previ-
ous-page() action may produce calls to the XmNgainPrima-
ryCallback procedures. See callback description for more in-
formation.

In vertical writing, if called without an argument, scrolls
the viewing window up one page of text.

process-bdrag()
If the pointer is within the selection, this action starts a
drag operation for the selection. This action sets the XmN-
convertProc of the DragContext to a function that calls the
XmNconvertCallback procedures, possibly multiple times, for
the _MOTIF_DROP selection.

If no selection exists or the pointer is outside the selec-
tion, this action prepares to start a secondary selection at
the pointer position.

Note:

Note that when dragging a secondary selection to a
different widget, focus will shift momentarily to the
second widget, and then back to the original widget.
This will generate callbacks to the XmNlosingFocus-
Callback procedures as focus is lost (by each widget)
as well as callbacks to the XmNfocusCallback proce-
dures as focus is regained.

process-cancel():
Cancels the current extend-adjust(), secondary-adjust() or
process-bdrag() operation and leaves the selection state as
it was before the operation; otherwise, and if the parent is
a manager, passes the event to the parent.

process-down(extend):
If XmNeditMode is XmSINGLE_LINE_EDIT, and XmNnavigationType
is XmNONE, traverses to the widget below the current one in
the tab group.

If XmNeditMode is XmMULTI_LINE_EDIT and this action is called
with an argument of extend, moves the insertion cursor as in
the case of no argument and extends the current selection.

In this case, the action will produce the XmNlosingFocusCall-
back callbacks with reason value XmCR_LOSING_FOCUS.

tab group if the direction argument is Next, or to the previ-
ous tab group if the direction is Prev. If XmNeditMode is Xm-
MULTI_LINE_EDIT, and the direction is Next, the action in-
serts a tab. The Prev direction has no effect with Xm-
MULTI_LINE_EDIT. In the Text widget, there is a preset tab
stop at every eighth columns.

Redraws the contents of the text window.

The redraw-display() action produces no callbacks.

scroll-cursor-vertically(percentage):
Scrolls the line containing the insertion cursor vertically
to an intermediate position in the visible window based on an
input percentage. A value of 0 indicates the top of the win-
dow; a value of 100, the bottom of the window. If this action
is called with no argument, the line containing the insertion
cursor is scrolled vertically to a new position designated by
the y position of the event passed to the routine.

The select-start() action may produce calls to the XmNgain-
PrimaryCallback procedures.

self-insert():
If XmNpendingDelete is True and the cursor is not disjoint
from the current selection, deletes the entire selection.
Inserts the character associated with the key pressed at the
insertion cursor.

The self-insert() action produces calls to the XmNmodifyVeri-
fyCallback procedures with reason value XmCR_MODIFY-
ING_TEXT_VALUE, the XmNvalueChangedCallback procedures with
reason value XmCR_VALUE_CHANGED, and the XmNmotionVerifyCall-
back procedures with reason value XmCR_MOVING_INSERT_CURSOR.

set-anchor():
Resets the anchor point for extended selections. Resets the
destination of secondary selection actions.

The set-selection-hint() action produces no callbacks.

toggle-add-mode():
Toggles the state of Add Mode.

The toggle-add-mode() action produces no callbacks.

toggle-overstrike():
Toggles the state of the text insertion mode. By default,
characters typed into the Text widget are inserted at the po-
sition of the insertion cursor. In overstrike mode, charac-
ters entered into the Text widget replace the characters that
directly follow the insertion cursor. In overstrike mode,
when the end of a line is reached, characters are appended to
the end of the line.

The following traversal actions generate no callbacks unless
they result in the loss of focus by the widget in question,
as when XmNnavigationType is XmNONE. In this case, they pro-
duce calls to the XmNlosingFocusCallback procedures, with
reason value XmCR_FOCUS_MOVED.

traverse-home():
Traverses to the first widget in the tab group.

traverse-next():
Traverses to the next widget in the tab group.
