Note: QMenuBar has to have ownership of the QMenu in order this signal to work. The table below outlines the strings looked for and where the entry is placed if matched: If an entry is moved its slots will still fire as if it was in the original place. These strings are translated (using QObject::tr()) in the "QMenuBar" context. The merging functionality is based on string matching the title of a QMenu entry. Qt for macOS also provides a menu bar merging feature to make QMenuBar conform more closely to accepted macOS menu bar layout. If you have multiple menu bars in one dialog the outermost menu bar (normally inside a widget with widget flag Qt::Window) will be used for the system-wide menu bar. On macOS and on certain Linux desktop environments such as Ubuntu Unity, QMenuBar is a wrapper for using the system-wide menu bar. For example, Windows systems are often configured so that the underlined character mnemonics that indicate keyboard shortcuts for items in the menu bar are only shown when the Alt key is pressed. Platform Dependent Look and Feelĭifferent platforms have different requirements for the appearance of menu bars and their behavior when the user interacts with them. These actions can then be inserted into menus in the usual way see the QMenu documentation for more details. Widgets can be added to menus by using instances of the QWidgetAction class to hold them. Menu items may be removed with removeAction(). FileMenu = menuBar() - >addMenu(tr( "&File"))
