NAME
XmMenuShell — The MenuShell widget class "XmMenuShell" "widget class" "MenuShell"
SYNOPSIS
#include <Xm/MenuShell.h>
DESCRIPTION
The MenuShell widget is a custom OverrideShell widget. An OverrideShell widget bypasses mwm when
displaying itself. It is designed specifically to contain Popup or Pulldown menu panes.
Most application writers never encounter this widget if they use the menu-system convenience functions,
XmCreatePopupMenu or XmCreatePulldown Menu, to create a Popup or Pulldown menu pane. The convenience
functions automatically create a MenuShell widget as the parent of the menu pane. 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 menu pane, the MenuShell's parent must be the widget
from which the Popup menu pane is popped up.
• If the MenuShell is for a menu pane that is pulled down from a Popup or another Pulldown menu pane,
the MenuShell's parent must be the Popup or Pulldown menu pane.
• If the MenuShell is for a menu pane that is pulled down from a MenuBar, the MenuShell's parent must
be the MenuBar.
• If the MenuShell is for a Pulldown menu pane 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 corresponding 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 0 (zero) minus the value of XmNborderWidth.
MenuShell uses the XmQTmenuSystem trait and holds the XmQTspecifyRenderTable trait.
Classes
MenuShell inherits behavior, resources, and traits from Core, Composite, Shell, and OverrideShell.
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 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).
