Sets the video window to the foreground and optionally gives it focus.
void DoSetWindowForeground( BOOL bFocus );
Parameters
- bFocus
- Value that specifies whether the video window will have focus.
A value of TRUE gives it focus and FALSE does not.
Return Values
No return value.
Remarks
DirectShow provides this method to make it easy for applications to move video windows to the foreground; usually, it is programatically complex for a thread associated with one window to affect a window associated with a different thread. This method passes the WM_SHOWWINDOW message to the video window's renderer, so the application's window procedure must handle this message and bring the appropriate window to the foreground and give it focus, if specified.
