Not the whole menu bar, but most menu items. > First question: is it possible to override Qt's behavior on a Macintosh? > > In Qt, to make the shortcuts for edit actions work, individual widgets like > QLineEdit filter key press events looking for shortcut keystrokes.

I just recently figured out how to get the menu shortcuts working in QFileDialog: see QTBUG-17291 and https://codereview.qt-project.org/#change,82404 The basis of it is that the native menu items need to have a "nil" target which means they go to the first responder, which is the native widget that has focus. Then the OS will intercept the keystrokes that are shortcuts for those menu items, and Qt will not see them, but they will work with the native widgets. Qt uses a native file dialog, so it's appropriate in that case. There may be other cases when we need to do that, but none that I know of for sure yet. But I guess having shortcuts work in Qt widget-based dialogs is a different story anyway. You can write up a bug about this, and provide an example to demonstrate if possible. _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
