Convenience Functions

DtCreateMenuButton() is a convenience function that creates a Common Desktop Environment widget.

DtMenuButton widget is a subclass of XmLabel class. Visually, DtMenuButton widget has a label string and a menu glyph. The menu glyph always appears on the right end of the widget and, by default, is a downward pointing arrow.

DtMenuButton widget has an implicitly created submenu attached to it. The submenu is a pop-up menu and has this DtMenuButton widget as its parent. The name of the implicitly created submenu is obtained by prefixing submenu_ to the name of this DtMenuButton widget. You can obtain the widget ID of the submenu by setting an XtGetValues on DtNsubMenuId resource of this DtMenuButton widget. The implicitly created submenu must not be destroyed by the user of this widget.

The submenu can be popped up by pressing the menu post button (see XmNmenuPost resource of XmRowColumn) anywhere on the DtMenuButton widget or by pressing the Motif Cancel key (usually Escape).
