If you enable mouse tracking then yes. But you'll have to do it in an event filter which you have to apply on your central widget and any of its subwidgets, because if a subwidget handles a mouse move event itself, it won't propagate it to the parent. Of course you'll have to calculate the coordinates in the main window coordinate system. Lots of work
