Gets a handle to the current screen that can be passed to the window manager

#include <smmwuser.h>

HWND sm_mw_drawingarea(void);

#include <smxmuser.h>

Widget sm_xm_drawingarea(void);

Motif, Windows; C only

• · Success: On Windows, an HWND handle to the window; on Motif, a Widget ID.

• · Failure: NULL if there is no current screen.

sm_mw_drawingarea and sm_xm_drawingarea get a handle to the current screen—in the case of Windows, a HWND handle; under Motif, a Widget ID. Use these functions with sm_translatecoords to place objects such as bitmapped graphics or custom widgets on a Panther screen. Refer to sm_translatecoords for a Windows example that uses this function.

Note: The Widget ID that sm_xm_drawingarea returns is not a recognizable X widget type. Consequently, you cannot directly call XmAddCallback with it. To use this Widget ID, you must call XmAddEventHandler.
