How to paint (QPainter) on a label ?

[d@nyal]

Hi,
I have several labels on my screen(mainwindow.ui) And I need to draw on them(Overlay).
Unfortunately "Qpainter" just draws behind labels.

void MainWindow::paintEvent( QPaintEvent * event )
{
     QPainter painter(this);
     painter.setPen(QPen(Qt::black, 2));
 
     //ui->pushButton->clearFocus();
     //ui->pushButton->setAutoFillBackground(true);
     //ui->pushButton->setBackgroundRole();
     //ui->pushButton->setForegroundRole();
 
 
     //painter.setBackgroundMode();
 
     QPainterPath path;
     path.moveTo(qrand() % 80, qrand() % 320);
     path.cubicTo(200, 80, 320, 80, 480, 320);
     painter.setPen(QPen(Qt::black, 8));
     painter.drawPath(path);
}

void MainWindow::paintEvent( QPaintEvent * event )
{
     QPainter painter(this);
     painter.setPen(QPen(Qt::black, 2));

     //ui->pushButton->clearFocus();
     //ui->pushButton->setAutoFillBackground(true);
     //ui->pushButton->setBackgroundRole();
     //ui->pushButton->setForegroundRole();

     
     //painter.setBackgroundMode();
     
     QPainterPath path;
     path.moveTo(qrand() % 80, qrand() % 320);
     path.cubicTo(200, 80, 320, 80, 480, 320);
     painter.setPen(QPen(Qt::black, 8));
     painter.drawPath(path);
}

I searched for lots of beheviars belonging "QPainter" and "QLabel".

Can you guide me how can I fix it?


Thanks.

Some tips:
You paint on the main window "canvas".
Labels are put on top of the main window.
So, if you want to paint on top of the labels, you need to paint in the labels
