For the iPhone VM I return a complex event type, which then points to Smalltalk objects which are the representation of the touch events. For location and acceleration data I return the actual objective-C objects. This data is then processed by EventSensor. If you choose to push the responsibility to the VM for creating event objects then you need to be cognizant of the fact that whatever is proposed has to change very little over time, otherwise you end up with the issue of image versus VM compatibility and the fact that VM version changes proceed at a slow rate. -- = = = ======================================================================== John M.
