[Interest] QtMacExtras don't work outside QtMacExtras

[Sensei]

Dear all,

after the new 5.0.2 update I was eager to give qt5 a try again, and see 
if QtMacExtras wasn't a bad addition.

So I compiled and installed QtMacExtras, all went fine. I've tried from 
the command line one example, the macunifiedtoolbar one, *from the 
QtMacExtras directory*. It compiled and it run just fine. From the 
command line.

Next, try to get the "application" widget example in qt5 use a native 
toolbar. All I did is this, firing up the Qt Creator:

- in the .pro I wrote

	QT += widgets macextras

- in the .h I forward-declared QtMacUnifiedToolBar and

	#ifdef Q_OS_MAC
	    QtMacUnifiedToolBar *fileToolBar;
	#else
	    QToolBar *fileToolBar;
	#endif

- only one toolbar remains now, the fileToolBar

- in the source I added

	#ifdef Q_OS_MAC
	    fileToolBar = new QtMacUnifiedToolBar(this);
	#else
	    fileToolBar = addToolBar(tr("File"));
	#endif



Now I've got TONS of errors, mainly because, as far as I understand, 
there is a type mismatch in handling source files, treated as 
Objective-C instead of Objective-C++:

Not that from the command line changes something:

Is anyone using this additional package on the mac? Any hints on why the 
macextras example worked, while the Qt example doesn't? I don't know 
what I am doing wrong here.

Thanks & Cheers!
