1194 Here is what the Qt documentation says about how a menubar is chosen:
1196 1) If the window has a QMenuBar then it is used. 2) If the window
1197 is a modal then its menubar is used. If no menubar is specified
1198 then a default menubar is used (as documented below) 3) If the
1199 window has no parent then the default menubar is used (as
1202 The above 3 steps are applied all the way up the parent window
1203 chain until one of the above are satisifed. If all else fails a
1204 default menubar will be created, the default menubar on Qt/Mac is
1205 an empty menubar, however you can create a different default
1206 menubar by creating a parentless QMenuBar, the first one created
1207 will thus be designated the default menubar, and will be used
1208 whenever a default menubar is needed.
1210 Thus, for Qt/Mac, we add the menus to a free standing menubar, so
1211 that this menubar will be used also when one of LyX' dialogs has
