The get_FullScreenMode method queries whether the video renderer is in full-screen mode.
HRESULT get_FullScreenMode( long *FullScreenMode );
[out] Pointer to a variable that receives the value OATRUE if the video renderer is in full-screen mode, or OAFALSE otherwise.
Possible return values include the following:
|E_NOTIMPL||This filter does not support full-screen mode.|
|VFW_E_NOT_CONNECTED||The video renderer filter is not connected.|
When the Filter Graph Manager is switching to full-screen mode, it calls this method to determine whether the current video renderer supports this mode. If the renderer does not have inherent support for full-screen playback, it should return E_NOTIMPL. If if does, it should return S_OK, and also return the correct value in the FullScreenMode parameter.
