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 XmMENUPULLDOWN 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:
⊕ If the Pulldown MenuPane is to be pulled down from a
MenuBar, its parent must be the MenuBar.
⊕ If the Pulldown MenuPane is to be pulled down from a
Popup or another Pulldown MenuPane, its parent must be
that Popup or Pulldown MenuPane.
⊕ If the Pulldown MenuPane is to be pulled down from an
OptionMenu, its parent must be the same as the
OptionMenu parent.
⊕ Specifies the parent widget ID
⊕ Specifies the name of the created widget
⊕ Specifies the argument list
⊕ Specifies the number of attribute/value pairs in the
argument list (arglist)
PullDown MenuPanes support tear-off capabilities for tear-
off menus through XmRowColumn resources. For a complete
definition of RowColumn and its associated resources, see

RETURN VALUE
Returns the RowColumn widget ID.
