XmTrackingEvent(3) Library Functions Manual XmTrackingEvent(3) NAME XmTrackingEvent -- A Toolkit function that provides a modal interaction SYNOPSIS #include <Xm/Xm.h> Widget XmTrackingEvent( Widget widget, Cursor cursor, Boolean confine_to, XEvent *event_return); DESCRIPTION XmTrackingEvent provides a modal interface for selection of a component. It is intended to support context help. The function calls the XmUpdate- Display function. XmTrackingEvent then grabs the pointer and discards suc- ceeding events until BSelect is released or a key is pressed and then re- leased. The function then returns the widget or gadget that contains the pointer when BSelect is released or a key is released, and ungrabs the pointer. widget Specifies the widget ID of a widget to use as the basis of the modal interaction. That is, the widget within which the interac- tion must occur, usually a top-level shell. cursor Specifies the cursor to be used for the pointer during the inter- action. This is a standard X cursor name. confine_toSpecifies whether or not the cursor should be confined to widget. event_return Returns the ButtonRelease or KeyRelease event that causes the function to return. RETURN Returns the widget or gadget that contains the pointer when BSelect is re- leased or a key is released. If no widget or gadget contains the pointer, the function returns NULL.
