Given that your compiler error concerns converting a HelpEvent to a
MouseEvent,my guess would be that the problem is that the listener
which is receiving your HelpEvent event expects to receive a
MouseEvent. This is a piece of code which you have not yet shown us:
i.e. the listener function for the HelpEvent.
