133 Here is what the Qt documentation says about how a menubar is chosen:
135 1) If the window has a QMenuBar then it is used. 2) If the window
136 is a modal then its menubar is used. If no menubar is specified
137 then a default menubar is used (as documented below) 3) If the
138 window has no parent then the default menubar is used (as
141 The above 3 steps are applied all the way up the parent window
142 chain until one of the above are satisifed. If all else fails a
143 default menubar will be created, the default menubar on Qt/Mac is
144 an empty menubar, however you can create a different default
145 menubar by creating a parentless QMenuBar, the first one created
146 will thus be designated the default menubar, and will be used
147 whenever a default menubar is needed.
149 Thus, for Qt/Mac, we add the menus to a free standing menubar, so
150 that this menubar will be used also when one of LyX' dialogs has
