XmMenuShell(3X) OSF/Motif XmMenuShell(3X)NAMEXmMenuShell - The MenuShell widget class
SYNOPSIS
#include <Xm/MenuShell.h>
DESCRIPTION
The MenuShell widget is a custom OverrideShell widget. An Over‐
rideShell widget bypasses mwm when displaying itself. It is designed
specifically to contain Popup or Pulldown MenuPanes.
Most application writers never encounter this widget if they use the
menu-system convenience functions, XmCreatePopupMenu or XmCreatePull‐
downMenu, to create a Popup or Pulldown MenuPane. The convenience
functions automatically create a MenuShell widget as the parent of the
MenuPane. However, if the convenience functions are not used, the
application programmer must create the required MenuShell. In this
case, it is important to note that the parent of the MenuShell depends
on the type of menu system being built. If the MenuShell is for the
top-level Popup MenuPane, the MenuShell's parent must be the widget
from which the Popup MenuPane is popped up. If the MenuShell is for a
MenuPane that is pulled down from a Popup or another Pulldown MenuPane,
the MenuShell's parent must be the Popup or Pulldown MenuPane. If the
MenuShell is for a MenuPane that is pulled down from a MenuBar, the
MenuShell's parent must be the MenuBar. If the MenuShell is for a
Pulldown MenuPane in an OptionMenu, the MenuShell's parent must be the
OptionMenu's parent.
Setting XmNheight, XmNwidth, or XmNborderWidth for either a MenuShell
or its child sets that resource to the same value in both the parent
and the child. An application should always specify these resources
for the child, not the parent.
For the managed child of a MenuShell, regardless of the value of the
shell's XmNallowShellResize, setting XmNx or XmNy sets the correspond‐
ing resource of the parent but does not change the child's position
relative to the parent. XtGetValues for the child's XmNx or XmNy
yields the value of the corresponding resource in the parent. The x
and y coordinates of the child's upper left outside corner relative to
the parent's upper left inside corner are both zero minus the value of
XmNborderWidth.
Classes
MenuShell inherits behavior and resources from Core, Composite, Shell,
and OverrideShell classes.
The class pointer is xmMenuShellWidgetClass.
The class name is XmMenuShell.
New Resources
MenuShell overrides the XmNallowShellResize resource in Shell. 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 refer‐
ence 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 pre‐
fix 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 font list used for MenuShell's button descendants. If
this value is NULL at initialization and if the value of XmNdefault‐
FontList is not NULL, XmNbuttonFontList is initialized to the value of
XmNdefaultFontList. If the value of XmNdefaultFontList is NULL, XmN‐
buttonFontList is initialized by looking up the parent hierarchy of the
widget for an ancestor that is a subclass of the XmBulletinBoard, Ven‐
dorShell, or XmMenuShell widget class. If such an ancestor is found,
XmNbuttonFontList is initialized to the XmNbuttonFontList of the ances‐
tor widget. If no such ancestor is found, the default is implementa‐
tion dependent. Specifies a default font list for MenuShell's descen‐
dants. This resource is obsolete and exists for compatibility with
earlier releases. It has been replaced by XmNbuttonFontList and XmNla‐
belFontList. Specifies the font list used for MenuShell's label
descendants (Labels and LabelGadgets). If this value is NULL at ini‐
tialization and if the value of XmNdefaultFontList is not NULL, XmNla‐
belFontList is initialized to the value of XmNdefaultFontList. If the
value of XmNdefaultFontList is NULL, XmNlabelFontList is initialized by
looking up the parent hierarchy of the widget for an ancestor that is a
subclass of the XmBulletinBoard, VendorShell, or XmMenuShell widget
class. If such an ancestor is found, XmNlabelFontList is initialized
to the XmNlabelFontList of the ancestor widget. If no such ancestor is
found, the default is implementation dependent.
Inherited Resources
MenuShell inherits behavior and resources from the following super‐
classes. For a complete description of each resource, refer to the man
page for that superclass. The following tables define a set of widget
resources used by the programmer to specify data. The programmer can
set the resource values for these 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).

Action Routines
The XmMenuShell action routines are described below: Disables keyboard
traversal for the menu, enables mouse traversal, and unposts any menus
posted by this menu. Unposts the menu hierarchy and, when the shell's
keyboard focus policy is XmEXPLICIT, restores focus to the widget that
had the focus before the menu system was entered. In a toplevel Pull‐
down MenuPane from a MenuBar, unposts the menu, disarms the MenuBar
CascadeButton and the MenuBar, and, when the shell's keyboard focus
policy is XmEXPLICT, restores keyboard focus to the widget that had the
focus before the MenuBar was entered. In other Pulldown MenuPanes,
unposts the menu.
In a Popup MenuPane, unposts the menu, and, when the shell's keyboard
focus policy is XmEXPLICT, restores keyboard focus to the widget from
which the menu was posted.
Virtual Bindings
The bindings for virtual keys are vendor specific. For information
