- Description
The OnDestroy() event is triggered by the TDx_DrawVideoPortContainer::Destroy() method, just before the TDx_DrawVideoPortContainer internal LPDDVIDEOPORTCONTAINER interface is destroyed.
Note: This event is an ideal place to place code that reverses the results of the TDx_DrawVideoPortContainer::OnCreate() event. For example, assume you have already setup the TDx_DrawVideoPortContainer::OnCreate() event to retrieve the component's capabilities, Create() a dependant component and allocate some memory;
You can then fully automate and insulate your code on a per-component basis by placing code in the TDx_DrawVideoPortContainer::OnDestroy() event to deallocate memory, Destroy() the dependant components and, when required, destroy the capabilities component.
