       XmCreateOptionMenu — A RowColumn widget convenience creation function "XmCreateOptionMenu"
       "creation functions" "XmCreateOptionMenu"


       #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

       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 undefined.

       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

       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

       Option Menu Label Gadget

       Option Menu Cascade Button
