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 resource values.

Classes

PanedWindow inherits behavior and resources from the Core, Composite, Constraint, 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 programmer to specify data. The programmer can also set the resource values 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).

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 vertical layout, the children are laid out in a vertically tiled format. 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 repositioned when programmatic changes are being made to the PanedWindow. 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 resource 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.

XmNspacing

Specifies 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 requests to alter the height of the pane. If False, it always denies 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 beginning of the list. The value can also be specified as XmLAST_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 positions 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 insert the specified widget into its parent's child list as described 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.

Inherited Resources

PanedWindow inherits behavior and resources from the superclasses described in the following tables. For a complete description of each resource, refer to the reference page for that superclass.

Translations

XmPanedWindow 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 format, please refer to the X Toolkit Instrinsics Documentation.

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 position 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
