I have just installed Qt 5.3.1 from qt-project.org and…. Qt Creator doesn’t supports global menu in Unity :-( Goggling doesn’t helps me at all.
After a little bit tracing I see that it uses it’s own plugins directory and of course it have no libappmenu-qt5.so
So we need just few commands to fix this:
sudo apt−get install libgtk2.0−dev libdbusmenu−qt5−dev cd /tmp apt−get source appmenu−qt5 cd appmenu−qt5−0.3.0+14.04.20140415/src ~/Qt/5.3/gcc_64/bin/qmake src.pro make test −d ~/Qt/Tools/QtCreator/bin/plugins/platformthemes || mkdir ~/Qt/Tools/QtCreator/bin/plugins/platformthemes cp libappmenu−qt5.so ~/Qt/Tools/QtCreator/bin/plugins/platformthemes chmod 755 ~/Qt/Tools/QtCreator/bin/plugins/platformthemes
thats all :)
