Tim,
During my final year project development (Poker game) I too noticed
the problem with double clicking on an element. I used this method on
my "click" event listeners:
public boolean isSingleClick(Event evt)
{
MouseEvent me=(MouseEvent)evt;
return me.getDetail()==1;
}
where the MouseEvent is a org.w3c.dom.events.MouseEvent and not a
standard java.awt.event.MouseEvent. This seemed to fix most of the
problems I was having, however this is still the odd occasion where it
does a double-click (not sure if its me or this dodgy mouse). I
consequently removed the flags that I was originally using and it
seemed to work fine.
As to the two key listeners, it may be useful to have a brief
explanation of what the listeners do and if the affect each other in a
major way. I would imagine that the problem is similar to the problem
a double-click would have, and I did have some problems with the lock
not occuring quickly enough when doing a double-click. Sorry if this
is waffle, its a little hard to explain :/
Hope this helps,
Lewis
