XmMenuShell(3X) X11 SDE 5.4R3.00 XmMenuShell(3X)
NAME
XmMenuShell--The MenuShell widget class
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 MenuPanes.
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 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 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 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
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).
XmMenuShell Resource Set

------------------------------------------------------------------------
XmNbuttonFontList XmCButtonFontList XmFontList dynamic CSG
XmNdefaultFontList XmCDefaultFontList XmFontList dynamic CG
XmNlabelFontList XmCLabelFontList XmFontList dynamic CSG
XmNbuttonFontList
Specifies the font list used for MenuShell's button
descendants. If this value is NULL at initialization and
if the value of XmNdefaultFontList is not NULL,
XmNbuttonFontList is initialized to the value of
XmNdefaultFontList. If the value of XmNdefaultFontList is
NULL, XmNbuttonFontList 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,
XmNbuttonFontList is initialized to the XmNbuttonFontList
of the ancestor widget. If no such ancestor is found, the
default is implementation dependent.
XmNdefaultFontList
Specifies a default font list for MenuShell's descendants.
This resource is obsolete and exists for compatibility with
earlier releases. It has been replaced by
XmNbuttonFontList and XmNlabelFontList.
XmNlabelFontList
Specifies the font list used for MenuShell's label
descendants (Labels and LabelGadgets). If this value is
NULL at initialization and if the value of
XmNdefaultFontList is not NULL, XmNlabelFontList 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
superclasses. 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).

Translations
The XmMenuShell translations are listed below. These translations
may not directly correspond to a translation table. BSelect
Press: ClearTraversal() BSelect Release:MenuShellPopdownDone()
Action Routines
The XmMenuShell action routines are described below:
ClearTraversal():
Disables keyboard traversal for the menu, enables mouse
traversal, and unposts any menus posted by this menu.
MenuShellPopdownDone():
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.
MenuShellPopdownOne():
In a toplevel Pulldown 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
about bindings for virtual buttons and keys, see VirtualBindings(3X).
