NAME
XmCreatePulldownMenu - a RowColumn widget convenience creation function.
SYNOPSIS
#include <Xm/RowColumn.h>
Widget XmCreatePulldownMenu (parent, name, arglist, argcount)
Widget parent;
String name;
ArgList arglist;
Cardinal argcount;
DESCRIPTION
XmCreatePulldownMenu creates an instance of a RowColumn widget of type
XmMENU_PULLDOWN and returns the associated widget ID. When using this
function to create the Pulldown MenuPane, a MenuShell widget is
automatically created as the parent of the MenuPane. If the widget
specified by the parent parameter is a Popup or a Pulldown MenuPane, the
MenuShell widget is created as a child of the parent's MenuShell;
otherwise, it is created as a child of the specified parent widget.
XmCreatePulldownMenu is provided as a convenience function for creating
RowColumn widgets configured to operate as Pulldown MenuPanes and is not
implemented as a separate widget class.
A Pulldown MenuPane displays a 3-D shadow, unless the feature is disabled
by the application. The shadow appears around the edge of the MenuPane.
A Pulldown MenuPane is used when creating submenus that are to be
attached to a CascadeButton or a CascadeButtonGadget. This is the case
for all MenuPanes that are part of a PulldownMenu system (a MenuBar), the
MenuPane associated with an OptionMenu, and any MenuPanes that cascade
from a Popup MenuPane. Pulldown MenuPanes that are to be associated with
an OptionMenu must be created before the OptionMenu is created.
The Pulldown MenuPane must be attached to a CascadeButton or
CascadeButtonGadget that resides in a MenuBar, a Popup MenuPane, a
Pulldown MenuPane, or an OptionMenu. This is done by using the button
resource XmNsubMenuId.
A MenuShell widget is required between the Pulldown MenuPane and its
parent. If the application uses this convenience function for creating a
Pulldown MenuPane, the MenuShell is automatically created as the real
parent of the MenuPane; otherwise, it is the application's responsibility
to create the MenuShell widget.
To function correctly when incorporated into a menu, the Pulldown
MenuPane's hierarchy must be considered; this hierarchy depends on the
type of menu system that is being built as follows:
