Hi,
Ideally we need to change EventHandler to support mouseWheel events and at
the same time,
perhaps, integrate EventHandlerPlus upwards too.
Otherwise, you will need to do as you suggested, make a Morph subclass
to handle stuff and use that as the in-betweener.
Regards, Gary

Sorry, that was a bit fuzzy.
My Morph is in a GeneralScrollPane. The GeneralScrollPane first sends
mouseWheel event to the scroller (my Morph). My Morph can scroll
horizonally
infinitely and handles the horizontal scrolling itself. Its mouseWheel
method
makes sure this only happens when the mouse is over it. Otherwise the
event
remains unhandled and the GeneralScrollPane handles it and scrolls
vertically.
Now I have another Morph (really just a plain Morph) in betwen. The
scroller
again sends it a mouseWheel, but its just a plain Morph and it does not
handle
it. The effect is that scrolling is always controlled by the scroll pane
(i.e.
vertically). I cannot seem to tell the scroll pane: don't ask your
scroller,
ask my Morph, nor can I tell this plain Morph: when someone asks you to
handle
a mouseWheel, don't just say no, ask my Morph instead.
Of course I can just create another Morph Class which passes all events to
its
owner. Is there anything more elegant?
