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).

RETURN

Returns the RowColumn widget ID.
