In this case one would just skip it. This looks interesting - from the Qt docs: "If you want all windows in a Mac application to share one menu bar, you must create a menu bar that does not have a parent. Create a parent-less menu bar this way: QMenuBar *menuBar = new QMenuBar(0); Note: Do not call QMainWindow::menuBar() to create the shared menu bar, because that menu bar will have theQMainWindow as its parent. That menu bar would only be displayed for the parent QMainWindow." This is the relevant code from LyX: GuiView.cpp, lines 434 and 435: // Fill up the menu bar. guiApp->menus().fillMenuBar(menuBar(), this, true); So, it's done exactly the wrong way. Stephan
