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

147 /* Since Qt 4.2, the qt/mac menu code has special code for
148 specifying the role of a menu entry. However, it does not
149 work very well with our scheme of creating menus on demand,
150 and therefore we need to put these entries in a special
151 invisible menu. (JMarc)
