The JoinFilterGraph method sends EC_WINDOW_DESTROYED event notification when a filter is removed from the filter graph.
Syntax
HRESULT JoinFilterGraph(
IBaseFilterGraph *pGraph,
LPCWSTR pName
);
Parameters
pGraph
Pointer to the filter graph to join.
pName
[in, string] Pointer to the name of the filter being added.
Return Value
No return value.
Remarks
This member function overrides the CBaseFilter::JoinFilterGraph member function. If the filter is leaving the filter graph (pGraph is null), it sends an EC_WINDOW_DESTROYED event notification so that the resource manager does not hold on to the renderer as a focus object.
