XmPanedWindow(3) Library Functions Manual XmPanedWindow(3) NAME XmPanedWindow -- The PanedWindow widget class SYNOPSIS #include <Xm/PanedW.h> DESCRIPTION PanedWindow is a composite widget that lays out children in a vertically tiled format. Children appear in top-to-bottom fashion, with the first child inserted appearing at the top of the PanedWindow and the last child inserted appearing at the bottom. The PanedWindow grows to match the width of its widest child and all other children are forced to this width. The height of the PanedWindow is equal to the sum of the heights of all its children, the spacing between them, and the size of the top and bottom mar- gins. The user can also adjust the size of the panes. To facilitate this adjust- ment, a pane control sash is created for most children. The sash appears as a square box positioned on the bottom of the pane that it controls. The user can adjust the size of a pane by using the mouse or keyboard. The PanedWindow is also a constraint widget, which means that it creates and manages a set of constraints for each child. You can specify a minimum and maximum size for each pane. The PanedWindow does not allow a pane to be resized below its minimum size or beyond its maximum size. Also, when the minimum size of a pane is equal to its maximum size, no control sash is presented for that pane or for the lowest pane. The default XmNinsertPosition procedure for PanedWindow causes all panes to appear first in the XmNchildren list and all sashes to appear after the panes. For a pane child, it returns the value of XmNpositionIndex if one has been specified for the child. Otherwise, it returns the number of panes in the PanedWindow's XmNchildren list. Other than the fact that all sashes appear after all panes, the insertion order of sashes is unspecified. This procedure also causes nonsash widgets to be inserted after other nonsash children but before any sashes. The behavior of PanedWindow is undefined if XmNinsertPosition is set to a procedure other than the default. All panes and sashes in a PanedWindow must be tab groups. When a pane is inserted as a child of the PanedWindow, if the pane's XmNnavigationType is not XmEXCLUSIVE_TAB_GROUP, PanedWindow sets it to XmSTICKY_TAB_GROUP. Descendants PanedWindow automatically creates for each paned window the descendants shown in the following table. An application can use XtName and the child list information to gain access to the named descendant. In addition, a user or an application can use the named descendant when specifying re- source values. +------------------+-------------------------+------------------------------------+ | Named Descendant | Class | Identity | +------------------+-------------------------+------------------------------------+ +------------------+-------------------------+------------------------------------+ +------------------+-------------------------+------------------------------------+ | Sash | subclass of XmPrimitive | sash | +------------------+-------------------------+------------------------------------+ | Separator | XmSeparatorGadget | dividing line between window panes | +------------------+-------------------------+------------------------------------+ +------------------+-------------------------+------------------------------------+ Classes PanedWindow inherits behavior and resources from the Core, Composite, Con- straint, and XmManager classes. The class pointer is xmPanedWindowWidgetClass. The class name is XmPanedWindow. New Resources The following table defines a set of widget resources used by the program- mer to specify data. The programmer can also set the resource values for the inherited classes to set attributes for this widget. To reference a re- source by name or by class in a .Xdefaults file, remove the XmN or XmC pre- fix 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 be- tween words). The codes in the access column indicate if the given re- source can be set at creation time (C), set by using XtSetValues (S), re- trieved by using XtGetValues (G), or is not applicable (N/A). +--------------------------------------------------------------------------------------------+ | | XmPanedWindow Resource Set | | | | Name | Class | Type | Default | Access | +------------------------+--------------------+---------------+---------------------+--------+ | XmNmarginHeight | XmCMarginHeight | Dimension | 3 | CSG | +------------------------+--------------------+---------------+---------------------+--------+ | XmNmarginWidth | XmCMarginWidth | Dimension | 3 | CSG | +------------------------+--------------------+---------------+---------------------+--------+ | XmNorientation | XmCOrientation | unsigned char | XmVERTICAL | CSG | +------------------------+--------------------+---------------+---------------------+--------+ | XmNrefigureMode | XmCBoolean | Boolean | True | CSG | +------------------------+--------------------+---------------+---------------------+--------+ | XmNsashHeight | XmCSashHeight | Dimension | 10 | CSG | +------------------------+--------------------+---------------+---------------------+--------+ | XmNsashIndent | XmCSashIndent | Position | -10 | CSG | +------------------------+--------------------+---------------+---------------------+--------+ | XmNsashShadowThickness | XmCShadowThickness | Dimension | dynamic | CSG | +------------------------+--------------------+---------------+---------------------+--------+ | XmNsashWidth | XmCSashWidth | Dimension | 10 | CSG | +------------------------+--------------------+---------------+---------------------+--------+ | XmNsashCursor | XmCSashCursor | Cursor | sb_h/v_double_arrow | CSG | +------------------------+--------------------+---------------+---------------------+--------+ | XmNseparatorOn | XmCSeparatorOn | Boolean | True | CSG | +------------------------+--------------------+---------------+---------------------+--------+ | XmNspacing | XmCSpacing | Dimension | 8 | CSG | +------------------------+--------------------+---------------+---------------------+--------+ +------------------------+--------------------+---------------+---------------------+--------+ XmNmarginHeight Specifies the distance between the top and bottom edges of the PanedWindow and its children. XmNmarginWidth Specifies the distance between the left and right edges of the PanedWindow and its children. XmNorientation Specifies the layout as either vertical (with the XmVERTICAL value) or horizontal (with the XmHORIZONTAL value). In the verti- cal layout, the children are laid out in a vertically tiled for- mat. In the horizontal layout, the children are laid out in a horizontal layout, with the sash moveable along the horizontal axis. XmNrefigureMode Determines whether the panes' positions are recomputed and repo- sitioned when programmatic changes are being made to the Paned- Window. Setting this resource to True resets the children to their appropriate positions. XmNsashHeight Specifies the height of the sash. XmNsashIndent Specifies the horizontal placement of the sash along each pane. A positive value causes the sash to be offset from the near (left) side of the PanedWindow, and a negative value causes the sash to be offset from the far (right) side of the PanedWindow. If the offset is greater than the width of the PanedWindow minus the width of the sash, the sash is placed flush against the near side of the PanedWindow. Whether the placement actually corresponds to the left or right side of the PanedWindow depends on the XmNlayoutDirection re- source of the widget. XmNsashShadowThickness Specifies the thickness of the shadows of the sashes. XmNsashWidth Specifies the width of the sash. XmNseparatorOn Determines whether a separator is created between each of the panes. Setting this resource to True creates a Separator at the midpoint between each of the panes. XmNspacingSpecifies the distance between each child pane. +----------------------------------------------------------------------------+ | |XmPanedWindow Constraint Resource Set | | | Name | Class | Type | Default | Access | +------------------+------------------+-----------+-----------------+--------+ | XmNallowResize | XmCBoolean | Boolean | False | CSG | +------------------+------------------+-----------+-----------------+--------+ | XmNpaneMaximum | XmCPaneMaximum | Dimension | 1000 | CSG | +------------------+------------------+-----------+-----------------+--------+ | XmNpaneMinimum | XmCPaneMinimum | Dimension | 1 | CSG | +------------------+------------------+-----------+-----------------+--------+ | XmNpositionIndex | XmCPositionIndex | short | XmLAST_POSITION | CSG | +------------------+------------------+-----------+-----------------+--------+ | XmNskipAdjust | XmCBoolean | Boolean | False | CSG | +------------------+------------------+-----------+-----------------+--------+ +------------------+------------------+-----------+-----------------+--------+ XmNallowResize Allows an application to specify whether the PanedWindow should allow a pane to request to be resized. This flag has an effect only after the PanedWindow and its children have been realized. If this flag is set to True, the PanedWindow tries to honor re- quests to alter the height of the pane. If False, it always de- nies pane requests to resize. XmNpaneMaximum Allows an application to specify the maximum size to which a pane may be resized. This value must be greater than the specified minimum. XmNpaneMinimum Allows an application to specify the minimum size to which a pane may be resized. This value must be greater than 0 (zero). XmNpositionIndex Specifies the position of the widget in its parent's list of children (the list of pane children, not including sashes). The value is an integer that is no less than 0 (zero) and no greater than the number of children in the list at the time the value is specified. A value of 0 means that the child is placed at the be- ginning of the list. The value can also be specified as Xm- LAST_POSITION (the default), which means that the child is placed at the end of the list. Any other value is ignored. XtGetValues returns the position of the widget in its parent's child list at the time of the call to XtGetValues. When a widget is inserted into its parent's child list, the posi- tions of any existing children that are greater than or equal to the specified widget's XmNpositionIndex are increased by 1. The effect of a call to XtSetValues for XmNpositionIndex is to remove the specified widget from its parent's child list, decrease by one the positions of any existing children that are greater than the specified widget's former position in the list, and then in- sert the specified widget into its parent's child list as de- scribed in the preceding sentence. XmNskipAdjust When set to True, this Boolean resource allows an application to specify that the PanedWindow should not automatically resize this pane.

inherits translations from XmManager. The translations for sashes within the PanedWindow are described in the following table. The following key names are listed in the X standard key event translation 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 description of the for- mat, please refer to the X Toolkit Instrinsics Documentation. ~c ~s ~m ~a <Btn1Down>: SashAction(Start) ~c ~s ~m ~a <Btn1Motion>: SashAction(Move) ~c ~s ~m ~a <Btn1Up>: SashAction(Commit) ~c ~s ~m ~a <Btn2Down>: SashAction(Start) ~c ~s ~m ~a <Btn2Motion>: SashAction(Move) ~c ~s ~m ~a <Btn2Up>: SashAction(Commit) :<Key><osfActivate>: PrimitiveParentActivate() :<Key><osfCancel>: PrimitiveParentCancel() :<Key><osfHelp>: Help() :c <Key><osfUp>: SashAction(Key,LargeIncr,Up) :<Key><osfUp>: SashAction(Key,DefaultIncr,Up) :c <Key><osfRight>: SashAction(Key,LargeIncr,Right) :<Key><osfRight>: SashAction(Key,DefaultIncr,Right) :c <Key><osfDown>: SashAction(Key,LargeIncr,Down) :<Key><osfDown>: SashAction(Key,DefaultIncr,Down) :c <Key><osfLeft>: SashAction(Key,LargeIncr,Left) :<Key><osfLeft>: SashAction(Key,DefaultIncr,Left) ~s ~m ~a <Key>Return: PrimitiveParentActivate() s ~m ~a <Key>Tab: PrevTabGroup() ~m ~a <Key>Tab: NextTabGroup() Action Routines The XmPanedWindow action routines are 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. NextTabGroup(): Moves the keyboard focus to the next tab group. By default, each pane and sash is a tab group. PrevTabGroup(): Moves the keyboard focus to the previous tab group. By default, each pane and sash is a tab group. SashAction(action) or SashAction(Key,increment,direction): The Start action activates the interactive placement of the pane's borders. The Move action causes the sash to track the po- sition of the pointer. If one of the panes reaches its minimum or maximum size, adjustment continues with the next adjustable pane. The Commit action ends sash motion. When sash action is caused by a keyboard event, the sash with the keyboard focus is moved according to the increment and direction specified. DefaultIncr adjusts the sash by one line. LargeIncr adjusts the sash by one view region. The direction is specified as either Up, Down, Left, or Right. Note that the SashAction action routine is not a direct action routine of the XmPanedWindow, but rather an action of the Sash control created by the XmPanedWindow. Additional Behavior This widget has the following additional behavior: <FocusIn>:Moves the keyboard focus to the sash and highlights it <FocusOut>: Unsets the keyboard focus in the sash and unhighlights it Virtual Bindings The bindings for virtual keys are vendor specific.
