This is controlled by Qt which is the GUI framework dependency used by Slicer. Therefore it is not something in the Slicer source code.

You can see information about a QMainWindow’s toolbar pop-up menu at: [https://doc.qt.io/qt-5/qmainwindow.html#createPopupMenu](https://doc.qt.io/qt-5/qmainwindow.html#createPopupMenu)
