[Moose-dev] [Roassal2] Pharo 4 MouseWheelEvent compatibility

Hello We use Roassal on Pharo 4, but we ran across another compatibility issue. On Pharo 4, MouseWheelEvent class got a little rework. It does not use symbols #up and #down as direction anymore, not even via accessors. TRMouseWheelEvent copies this direction, so because RTZoomableView looks for these symbols, it is no longer working on Pharo 4 (mouse wheel now just moves camera, but does not change scale). More info about this Pharo 4 change you might find here: http://forum.world.st/MouseWheelEvent-direction-in-Pharo-4-tp4806863p480686… I tried to make few changes to make it compatible in both Pharo 3 and 4. One option is just adding two methods into TRMouseWheelEvent which convert Pharo 4 direction to Pharo 3 direction, so only interface change is when creating TRMouseWheelEvent, usage of this event is absolutely same. http://www.mediafire.com/download/es70j9dko45da2b/mouseWheel_pharo3like.zip Second option is to rework TRMouseWheelEvent in the same way MouseWheelEvent got changed, so they will have same usage on Pharo 4, but it means even interface of TRMouseWheelEvent changes and everything that asks for its direction has to be changed, too. http://www.mediafire.com/download/38lwuwr1eauuur0/mouseWheel_pharo4like.zip Third option is to use your own solution instead of mine. And last solution might be just ignoring it and not trying to be compatible with both Pharo versions.
