This method is specific to version 3, or higher, of the OS/2 operating system.
This instance method updates the drawer after changes have been made to the set of objects in the Toolbar or drawer.
Syntax
wpRefreshDrawer(somSelf, ulDrawer)
Parameters
- somSelf (WPLaunchPad *) - input

- ulDrawer (ULONG) - input
- Toolbar or drawer being refreshed.

How to Override
This method can be overridden to know when the drawer is being refreshed. During the processing of **wpRefreshDrawer**, wpSetDrawerHWND is called to set **hwnd** to **NULLHANDLE** while the objects are being recreated. It then calls wpSetDrawerHWND to set **hwnd** back to handle of the frame window for the drawer.
Example Code
#define INCL_WINWORKPLACE #include <os2.h> WPLaunchPad *somSelf; /* Pointer to the object on which the method is being invoked. */ ULONG ulDrawer; /* Toolbar or drawer being refreshed. */ wpRefreshDrawer(somSelf, ulDrawer);
