81 Returns the top most window associated with widget.

83 Unlike QWidget::window(), this function does its best to find and return the
84 main application window associated with the given widget.
85
86 If widget itself is a dialog or its parent is a dialog, and that dialog has a
87 parent widget then this function will iterate through all those widgets to
88 find the top most window, which most of the time is the main window of the
89 application. By contrast, QWidget::window() would simply return the first
90 file dialog it encountered since it is the "next ancestor widget that has (or
91 could have) a window-system frame".
