MHuiEventHandler Class Reference

class MHuiEventHandler

MHuiEventHandler is an interface that can be derived by any object that want's to handle Hitchcock UI Toolkit events scheduled by HuiScheduler.

If an object wishes to process events from the toolkit, it should implement this interface.

Note:

The destructor will NOT cancel any pending commands enqueued to this object, so you must call eg. CHuiEnv::CancelCommands(this); to cancel still pending commands to prevent calling destroyed object.
