How to get 2 layers using Composition Modes in QPainter?

qwe3

Hi,

I would like to draw ( using QPainter and composition modes ) on the one widget 2 layers:

one, which is top layer - red color
one, which is bottom layer - blue color with black text in some position

I draw "transparent" ellipse, so I see blue layer.

I can do 2 layers: red and blue, transparent ellipse using only composition modes, but I can't get text to blue layer. There is not shown.

My code:

void someWidget::paintEvent(QPaintEvent *)
{
    QPainter painter(this);
    painter.setRenderHints(QPainter::Antialiasing);
    painter.setPen(Qt::NoPen);

    QPointF globalpoint = this->mapFromGlobal(QCursor::pos());

    painter.setCompositionMode(QPainter::CompositionMode_Source);
    painter.fillRect(0, 0, width(), height(), Qt::red);

    painter.setCompositionMode(QPainter::CompositionMode_DestinationIn);
    painter.setBrush(QColor(0,0,0,0));
    painter.drawEllipse(globalpoint, 200,200);

    painter.setCompositionMode(QPainter::CompositionMode_DestinationOver);
    painter.fillRect(0, 0, width(), height(), Qt::blue);

    painter.setPen(Qt::black);
    painter.drawText(100, 100, "Text");
}

EDIT:

I found solution:
I have to change an order:

    painter.setCompositionMode(QPainter::CompositionMode_DestinationOver);
    painter.setPen(Qt::black);
    painter.drawText(100, 100, "Text");
    painter.fillRect(0, 0, width(), height(), Qt::blue);
