       XmCreateOptionMenu — A RowColumn widget convenience creation function

       #include <Xm/RowColumn.h>
       Widget XmCreateOptionMenu(
       Widget parent,
       String name,
       ArgList arglist,
       Cardinal argcount);

       XmCreateOptionMenu creates an instance of a RowColumn widget of type
       XmMENU_OPTION and returns the associated widget ID.

       It is provided as a convenience function for creating a RowColumn
       widget configured to operate as an OptionMenu and is not implemented as
       a separate widget class.

       The OptionMenu widget is a specialized RowColumn manager composed of a
       label, a selection area, and a single Pulldown menu pane. When an
       application creates an OptionMenu widget, it supplies the label string
       and the Pulldown menu pane.  In order for the operation to be
       successful, there must be a valid XmNsubMenuId resource set when this
       function is called.  The LabelGadget and the selection area (a
       CascadeButtonGadget) are created by the OptionMenu.

       The OptionMenu's Pulldown menu pane must not contain any ToggleButtons
       or ToggleButtonGadgets.  The results of including CascadeButtons or
       CascadeButtonGadgets in the OptionMenu's Pulldown menu pane are

       An OptionMenu is laid out with the label displayed on one side of the
       widget and the selection area on the other side when XmNorientation is
       XmHORIZONTAL.  The layout of the label with respect to the selection
       area depends on the XmNlayoutDirection resource in the horizontal
       orientation.  If the value is XmVERTICAL, the label is above the
       selection area.  The selection area has a dual purpose; it displays the
       label of the last item selected from the associated Pulldown menu pane,
       and it provides the means for posting the Pulldown menu pane.

       The OptionMenu typically does not display any 3-D visuals around itself
       or the internal LabelGadget. By default, the internal
       CascadeButtonGadget has a visible 3-D shadow.  The application may
       change this by getting the CascadeButtonGadget ID using
       XmOptionButtonGadget, and then calling XtSetValues using the standard
       visual-related resources.

       The Pulldown menu pane is posted when the mouse pointer is moved over
       the selection area and a mouse button that is defined by OptionMenu's
       RowColumn parent is pressed.  The Pulldown menu pane is posted and
       positioned so that the last selected item is directly over the
       selection area. The mouse is then used to arm the desired menu item.
       When the mouse button is released, the armed menu item is selected and
       the label within the selection area is changed to match that of the
       selected item. By default, BSelect is used to interact with an
       OptionMenu.  The default can be changed with the RowColumn resource

       The OptionMenu also operates with the keyboard interface mechanism.  If
       the application has established a mnemonic with the OptionMenu,
       pressing <Alt> with the mnemonic causes the Pulldown menu pane to be
       posted with traversal enabled.  The standard traversal keys can then be
       used to move within the menu pane. Pressing <Return> or typing a
       mnemonic or accelerator for one of the menu items selects that item.

       An application may use the XmNmenuHistory resource to indicate which
       item in the Pulldown menu pane should be treated as the current choice
       and have its label displayed in the selection area. By default, the
       first selectable item in the Pulldown menu pane is used.

       parent    Specifies the parent widget ID

       name      Specifies the name of the created widget

       arglist   Specifies the argument list

       argcount  Specifies the number of attribute/value pairs in the argument
                 list (arglist)

       The user can specify resources in a resource file for the automatically
       created widgets and gadgets of an OptionMenu.  These widgets (or
       gadgets) and the associated OptionMenu areas are
