A RowColumn function that obtains the widget ID for the tear-off control in a menu
#include <Xm/RowColumn.h> Widget XmGetTearOffControl Widget menu
XmGetTearOffControl provides the application with the means for obtaining the widget ID of the internally created tear-off control in a tear-off menu.
RowColumn creates a tear-off control for a PulldownMenu or PopupMenu when the XmNtearOffModel resource is initialized or set to XmTEAR_OFF_ENABLED. The tear-off control is a widget that appears as the first element in the menu. The user tears off the menu by means of mouse or keyboard events in the tear-off control.
The tear-off control has Separator-like behavior. Once the application has obtained the widget ID of the tear-off control, it can set resources to specify the appearance of the control. The application or user can also set these resources in a resource file by using the name of the control, which is TearOffControl . For a list of the resources the application or user can set, see XmRowColumn (3).
For more information on tear-off menus and a complete definition of RowColumn and its associated resources, see XmRowColumn (3).
Returns the widget ID for the tear-off control, or NULL if no tear-off control exists. An application should not assume that the returned widget will be of any particular class.
