IUIAnimationManager2::SetManagerEventHandler method (uianimation.h)
Specifies a handler for animation manager status updates.
Syntax
HRESULT SetManagerEventHandler(
[in, optional] IUIAnimationManagerEventHandler2 *handler,
[in] BOOL fRegisterForNextAnimationEvent
);
Parameters
[in, optional] handler
The event handler to be called when the status of the animation manager changes.
The specified object must implement the IUIAnimationManagerEventHandler interface or be NULL. See Remarks for more info.
[in] fRegisterForNextAnimationEvent
If TRUE, specifies that IUIAnimationManager2::EstimateNextEventTime will incorporate handler into its estimate of the time interval until the next animation event. No default value.
Return value
Returns S_OK if successful; otherwise an HRESULT error code. See Windows Animation Error Codes for a list of error codes.
Remarks
Passing NULL for the handler parameter causes Windows Animation to release its reference to any handler object that you passed in earlier. This technique can be essential for breaking reference cycles without having to call the IUIAnimationManager2::Shutdown method.
