How set QLabel in a corner of Windows even when i do resize in QT?

I am currently working with OpenGL and i need to place a QLabel in a corner of my window, and when I make a resizing in the window, the label goes back to the corner of the window.

I am using the function

void MyClass::myFunction()
{
    label->move( mapToGlobal( QPoint( 460, 425 )));
}

And in my paintGL() method

void MyClass::paintGL
{
   myFunction();
}

but when i maximize the window, i can not put the label back in the corner. I have read other topics but i can not find the solution.

Ok, i found the solution.

replacing move method for setGeometry.

label->setGeometry((this->width() - label->sizeHint().width() / 2),
                   this->height() - label->sizeHint().height()/ 2,
                   label->sizeHint().width(), label->sizeHint().height());

thanks a lot.
