[Interest] How to use QtMacExtras in Qt 5.2 beta

[Yuë Liu]

Hello,

I found QtMacExtras API changed in Qt 5.2, for the use of unified
toobar, from commit
https://qt.gitorious.org/qt/qtmacextras/commit/24d45304aa363c9a08f7157d549cb37c07212108
it says we should use QMainWindow:: setUnifiedTitleAndToolBarOnMac()
again, I compiled the appication example which used that method, but
the unified toobar didn't appear. How to use unified toolbar on Mac in
Qt 5.2?

Thanks,
Yue Liu
