That code is handling kEventMouseWheel events, and the kEventParamMouseWheelDelta returns lines scrolled (rather than pixels), and doesn't support simultaneous horizontal and vertical scrolling. Instead we should probably upgrade to using kEventMouseScroll events, which return kEventParamMouseWheelSmoothVerticalDelta and kEventParamMouseWheelSmoothHorizontalDelta in pixels. -- Tristam MacDonald http://swiftcoder.wordpress.com/ --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "pyglet-users" group.
