112 /// Some special Qt/Mac support hacks
115 Here is what the Qt documentation says about how a menubar is chosen:
117 1) If the window has a QMenuBar then it is used. 2) If the window
118 is a modal then its menubar is used. If no menubar is specified
119 then a default menubar is used (as documented below) 3) If the
120 window has no parent then the default menubar is used (as
123 The above 3 steps are applied all the way up the parent window
124 chain until one of the above are satisifed. If all else fails a
125 default menubar will be created, the default menubar on Qt/Mac is
126 an empty menubar, however you can create a different default
127 menubar by creating a parentless QMenuBar, the first one created
128 will thus be designated the default menubar, and will be used
129 whenever a default menubar is needed.
131 Thus, for Qt/Mac, we add the menus to a free standing menubar, so
132 that this menubar will be used also when one of LyX' dialogs has
