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