if the mouse event is not used by the wallpaper, you should not call accepted() on the event. this lets it pass through and the widget/containment using the wallpaper can then do whatever it wants with it. whether or not that results in cycling through desktops or not is an implementation detail that the wallpaper should care about. :) > Question 2. > > In unlocked mode, should the mouse pointer become a little hand (or > something like that) to indicate that the view can be dragged?
