NAME
XmCreatePulldownMenu — A RowColumn widget convenience creation function
SYNOPSIS
#include <Xm/RowColumn.h>
Widget XmCreatePulldownMenu(
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.
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)
Specifies the number of attribute/value pairs in the argument list
(arglist). When this function is used to create the Pulldown menu
pane, a MenuShell widget is automatically created as the parent of the
menu pane. If the widget specified by the parent parameter is a Popup
or a Pulldown menu pane, the MenuShell widget is created as a child of
the parent 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 menu panes and is
not implemented as a separate widget class.
A Pulldown menu pane displays a 3-D shadow, unless the feature is
disabled by the application. The shadow appears around the edge of the
menu pane.
A Pulldown menu pane is used with submenus that are to be attached to a
CascadeButton or a CascadeButtonGadget. This is the case for all menu
panes that are part of a PulldownMenu system (a MenuBar), the menu pane
associated with an OptionMenu, and any menu panes that cascade from a
Popup menu pane. Pulldown menu panes that are to be associated with an
OptionMenu must be created before the OptionMenu is created.
The Pulldown menu pane must be attached to a CascadeButton or
CascadeButtonGadget that resides in a MenuBar, a Popup menu pane, a
Pulldown menu pane, or an OptionMenu. It is attached with the button
resource XmNsubMenuId.
A MenuShell widget is required between the Pulldown menu pane and its
parent. If the application uses this convenience function for creating
a Pulldown menu pane, the MenuShell is automatically created as the
real parent of the menu pane; otherwise, it is the application’s
responsibility to create the MenuShell widget.
To function correctly when incorporated into a menu, the Pulldown menu
pane’s hierarchy must be considered. This hierarchy depends on the type
of menu system that is being built, as follows:
· If the Pulldown menu pane is to be pulled down from a MenuBar,
its parent must be the MenuBar.
· If the Pulldown menu pane is to be pulled down from a Popup or
another Pulldown menu pane, its parent must be that Popup or
Pulldown menu pane.
· If the Pulldown menu pane is to be pulled down from an
OptionMenu, its parent must be the same as the OptionMenu parent.
PullDown menu panes support tear-off capabilities for tear-off menus
through XmRowColumn resources. For a complete definition of RowColumn
and its associated resources, see XmRowColumn(3).

Returns the RowColumn widget ID.
