NAME

SYNOPSIS

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

DESCRIPTION

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).
