[Interest] Buttons on QGLWidget not shown on Mac OSX 10.8 (Mountain Lion)

[Calogero Mauceri]

Hi all,

I have a QGLWidget rendering a 3D scene, and I have some QWidgets, 
actually buttons, on top of that view to add some controls to the 
QGLWidget. See the "Test" button on the top left corner of the attached 
figure.
The implementation is working greatly on Mac OSX 10.6 (from where I took 
the screen shot), but the button is not shown at all on Mac OSX 10.8. 
Actually the button is there but it seems completely transparent, I can 
click on it and the slot it is connected to is called. The same 
implementation works like a charm on Windows and linux too.
Is it a Qt bug or am I doing something wrong?

Here it is how I'm adding the button to the view:

MyQGLWidget::MyQGLWidget( QWidget* parent )
:    QGLWidget( parent )
{
     myButton = new QPushButton(this);
     myButton->setText("Test");
     myButton->move(0,0);

     QObject::connect( myButton, SIGNAL( clicked() ),
         this, SLOT( mySlot() ) );
}

I'm using latest Qt released, Qt 4.8.4.

Thanks in advance for your help,
     Calogero
