+The MenuButton widget is an area, often rectangular,
+that displays a graphic.  The graphic may be a text
+string containing multiple lines of characters in an 8
+bit or 16 bit character set (to be displayed with a
+\fIfont\fP), or in a multi-byte encoding (for use with
+a \fIfontset\fP).  The graphic may also be a bitmap or
+pixmap.
+.LP
+When the pointer cursor is on a MenuButton widget, the
+MenuButton becomes highlighted by drawing a rectangle
+around its perimeter.  This highlighting indicates
+that the MenuButton is ready for selection.  When a
+pointer button is pressed, the MenuButton widget will
+pop up the menu named in the \fBmenuName\fP resource.

+.IP \fBmenuName\fP 1.5i
+The name of a popup shell to popup as a menu.  The MenuButton
+will search for this name using \fBXtNameToWidget\fP starting
+with itself as the reference widget.  If the search is
+unsuccessful the widget will continue up the widget tree using
+each of its ancestors as the reference widget passed to
+\fBXtNameToWidget\fP.  If no widget of called \fBmenuName\fP is
+found by this algorithm, the widget will print a warning message
+and give up.  When the menu is found it will be popped up
+exclusive and spring_loaded.  The MenuButton widget does not
+copy the value of this resource into newly allocated memory. The
+application programmer must pass the resource value in
+nonvolatile memory.

+colors with \fBset\fP and \fBunset\fP
+.IP \(bu 5
+Processing application callbacks with \fBnotify\fP
+.IP \(bu 5

+.NH 3
+MenuButton Actions
+.LP
+The full list of actions supported by MenuButton is:
+.IP \fBhighlight\fP(\fIcondition\fP) 1.5i
+Displays the internal highlight border in the color (\fBforeground\fP
+or \fBbackground\fP ) that contrasts with the interior color of the
+Command widget.  The conditions \fBWhenUnset\fP and \fBAlways\fP are
+understood by this action procedure.  If no argument is passed,
+\fBWhenUnset\fP is assumed.
+.IP \fBunhighlight\fP(\|) 1.5i
+Displays the internal highlight border in the color (\fBXtNforeground\fP
+or \fBbackground\fP ) that matches the interior color of the
+MenuButton widget.
+.IP \fBset\fP(\|) 1.5i
+Enters the \fIset\fP state, in which \fBnotify\fP is possible.  This
+action causes the button to display its interior in the
+\fBforeground\fP color.  The label or bitmap is displayed in the
+\fBbackground\fP color.
+.IP \fBunset\fP(\|) 1.5i
+Cancels the \fIset\fP state and displays the interior of the button in the
+\fBbackground\fP color.  The label or bitmap is displayed in the
+\fBforeground\fP color.
+.IP \fBreset\fP(\|) 1.5i
+Cancels any \fBset\fP or \fBhighlight\fP and displays the interior of the
+button in the \fBbackground\fP color, with the label displayed in the
+\fBforeground\fP color.
+.IP \fBnotify\fP(\|) 1.5i
+When the button is in the \fBset\fP state this action calls all functions in
+the callback list named by the \fBcallback\fP resource.  The value of
+the call_data argument in these callback functions is undefined.
+.IP \fBPopupMenu\fP(\|) 1.5i
+Pops up the menu specified by the \fBmenuName\fP resource.
+.LP
+The MenuButton widget does not place a server grab on itself.
+Instead, PopupMenu is registered as a grab action.
+As a result, clients which popup menus without using XtMenuPopup
+or MenuPopup or PopupMenu in translations will fail to have a grab active.
+They should make a call to XtRegisterGrabAction on the appropriate action
+in the application initialization routine, or use a different translation.
