Comment 29 for bug 38753

Just had a thought. Recently (maybe with Qt 4) the 'What's this?' button seems to have had an excellent improvement: When you hover over a widget that has What's This text, the mouse cursor changes from a no-entry style to a question mark. Isn't this almost exactly what is needed to solve this bug?

On second thoughts it probably works by responding to the mouse move event for the whole app and modifying the cursor. So using this method would a) Do stuff on all mouse moves, and b) Need a way for the app to control when the window is raised (while respecting the window manager policies).
