NAME
XmPanedWindow -- 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 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 XmNposi-
tionIndex 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 inser-
tion order of sashes is unspecified. This procedure also causes non-
sash 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 XmNnavigation-
Type 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 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 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).

+-----------------------+--------------------+---------------+------------+--------+
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 chil-
dren 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 XmNlayoutDirec-
tion 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.

+-----------------+------------------+-----------+-----------------+--------+
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 XtGet-
Values.
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 XmN-
positionIndex is to remove the specified widget from its par-
ent's child list, decrease by one the positions of any exist-
ing 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 pre-
ceding sentence.
XmNskipAdjust
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 described in the
following table.
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.

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
Virtual Bindings
The bindings for virtual keys are vendor specific. For information
about bindings for virtual buttons and keys, see VirtualBindings(3).
