Hello, I faced performance problems when I tried to migrate my application to new GWT event system for onMouseMove events.
my application uses onMouseMove for dragNdrop and the performance dramatically reduced after migration. The problems I see as a reason are: before we had public void onMouseMove(Widget w, int x, int y) now we have onMouseMove(MouseMoveEvent event) in case I need to get the Widget that sent event I have to do cast - I've heard it is slow operation in GWT. It would be nice if GWT developers confirm it. Aditional two method calls are event.getX(), event.getY() . Don't know if method call in GWT is expensive. Question summary: Is someone noticed performance slow down with the new even system? How long the old even system will be supported? Am I right that cast is expensive operation in GWT? Is method call expensive in GWT? What else may slow down the performance of new even system?
