IUIAnimationTimer::SetTimerEventHandler method (uianimation.h)
Specifies a timer event handler.
Syntax
HRESULT SetTimerEventHandler(
[in, optional] IUIAnimationTimerEventHandler *handler
);
Parameters
[in, optional] handler
A timer event handler. The specified object must implement the IUIAnimationTimerEventHandler interface or be NULL. See Remarks.
Return value
If the method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code. See Windows Animation Error Codes for a list of error codes.
Remarks
Timing events include the OnPreUpdate, OnPostUpdate, and OnRenderingTooSlow methods of the IUIAnimationTimerEventHandler interface.
Passing NULL for the handler parameter causes Windows Animation to release its reference to any handler object you passed in earlier. This technique can be essential for breaking reference cycles without having to call the IUIAnimationManager::Shutdown method.
Examples
For an example, see Update the Animation Manager and Draw Frames.
