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 margins.
The user can also adjust the size of the panes. To facilitate this
adjustment, 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 sashes
to be inserted at the end of the list of children and causes non-sash
widgets to be inserted after other non-sash children but before any
sashes.
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.
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
Licensed material--property of copyright holder(s) 1
XmPanedWindow(3X) X11 SDE 5.4R3.00 XmPanedWindow(3X)
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.
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 may depend on the value of
the XmNstringDirection resource.
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.

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.
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 zero
and no greater than the number of children in the list at
the time the value is specified. A value of zero 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
Licensed material--property of copyright holder(s) 3
XmPanedWindow(3X) X11 SDE 5.4R3.00 XmPanedWindow(3X)
increased by one. 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 following
superclasses. For a complete description of each resource, refer to

Translations
XmPanedWindow inherits translations from XmManager.
The translations for sashes within the PanedWindow are listed below.
These translations may not directly correspond to a translation
table. BSelect Press: SashAction(Start) BSelect

Action Routines
The XmPanedWindow action routines are described below:
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.

XmPanedWindow(3X) X11 SDE 5.4R3.00 XmPanedWindow(3X)
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 or Down.
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 additional behavior described below:
<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. For information
about bindings for virtual buttons and keys, see VirtualBindings(3X).
