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