| Microsoft DirectX 9.0 |
Notifies a filter of the video renderer's window.
Parameters
lParam1
Handle to the window.
lParam2
Zero.
Default Action
This event is used internally by DirectShow. The filter graph manager does not pass this event to the application. Applications cannot override the default action for this event.
Remarks
When a video renderer is connected, it checks whether the upstream output pin supports the IMediaEventSink interface. If so, the renderer sends this event to the upstream filter.
