XmPanedWindow(3X) OSF/Motif XmPanedWindow(3X)NAMEXmPanedWindow - The PanedWindow widget class
SYNOPSIS
#include <Xm/PanedW.h>
DESCRIPTION
PanedWindow is a composite widget that lays out children in a verti‐
cally 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 cre‐
ates 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 XmNnavigation‐
Type 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 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).

Specifies the distance between the top and bottom edges of the Paned‐
Window and its children. Specifies the distance between the left and
right edges of the PanedWindow and its children. 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. Specifies the
height of the sash. 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. Specifies the thickness of the shadows of the sashes. Spec‐
ifies the width of the sash. 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. Specifies the
distance between each child pane.

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. Allows
an application to specify the maximum size to which a pane may be
resized. This value must be greater than the specified minimum.
Allows an application to specify the minimum size to which a pane may
be resized. This value must be greater than 0. Specifies the position
of the widget in its parent's list of children (the list of pane chil‐
dren, 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 speci‐
fied widget's XmNpositionIndex are 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 for‐
mer position in the list, and then insert the specified widget into its
parent's child list as described in the preceding sentence. When set
to True, this Boolean resource allows an application to specify that
the PanedWindow should not automatically resize this pane.

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.

lect Release:SashAction(Commit)

Action Routines
The XmPanedWindow action routines are described below: Calls the call‐
backs 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. Moves the keyboard focus to the next tab
group. By default each pane and sash is a tab group. Moves the key‐
board focus to the previous tab group. By default each pane and sash
is a tab group. 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 key‐
board focus is moved according to the increment and direction speci‐
fied. 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: Moves the key‐
board focus to the sash and highlights it. 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).
