How can I do it? </div></blockquote><div> </div></div></div><div dir="ltr">You have to create a QWidget that has the toplevel window as a parent, and ensure that it always occupies the whole interface.<div>To do that, you have to use setGeometry() as soon as it's shown the first time, and ensure that the geometry is updated everytime the parent (the top level window) is resized.</div><div><br>If you're using a QMainWindow, you might want to use the central widget as a reference, so that the menubar and statusbar will always be visible, alternatively you can use self.rect(), which works for other types of widgets/dialogs too, but might also be better for QMainWindow if you have other "special" widgets, like toolbars or dock
