[Qt] Please add qt_mac_set_dock_menu

[Felipe Monteiro de Carvalho]

Hello,

I am almost finishing the first native release of the magnifier for
Mac OS X =) and with lcl-qt

One thing I noticed however is that the dock menu doesn't respond to
user commands, and because Mac OS X assigns that menu whether I want
it or not, it would be nice to make it actually work. And to do that
it's necessary to use a platform specific function present in Qt and
called qt_mac_set_dock_menu

I couldn't find documentation for this functions (where are the docs
for loose functions??), so I don't know since when it is available. If
it's available at least since 4.2, it would be nice to have it added
=)

No hurry, you can wait for more requests before adding this. I just
thougth I would comment this here so I don't forget about this.

I asked on a Qt forum but I couldn't find any other way to make the
dock menu respond to user commands. (There is a Quit menu there, so
the user should expect to see the app quit when he presses it).

"It has always been possible to change the icon on the dock by using
QApplication::setIcon(). It is now also possible to set a QMenu for
the dock icon as well. This is available through a C++ function, but
is not in a header, so you need to extern it yourself.

    QMenu *menu = new QMenu;
    // Add actions to the menu
    // Connect them to slots
    ...
    extern void qt_mac_set_dock_menu(QMenu *);
    qt_mac_set_dock_menu(menu);"

thanks,
