* Name: nx_redrawreq
|
|
*
|
|
* Descripton:
|
|
* This will cause a NX re-draw callback to the client that owns the
|
|
* window. This is not normally called from user code, but may be
|
|
* used within middle-ware layers when redrawing is needed.
|
|
*
|
|
* Input Parameters:
|
|
* hwnd - Window handle
|
|
* rect - The rectangle that needs to be re-drawn (in window relative
|
|
* coordinates)
|
|
*
|
|
* Returned Value:
|
|
* None
|
|
*
