onVisibleChanged or onVisibilityChanged perhaps?  But it happens after the window is already closed, so you can do some auto-saving of data for example, but it's a bit late to pop up a FileDialog to prompt the user where to save (the FileDialog would have no visible parent window).  Otherwise you could override QWindow::event() and handle the close event, but it's inconvenient to write the C++ and then change your QML to use the custom subclass, for such an expected feature.  I guess we will need to think of an easier way.
