Paint QTableView with rounded corners.

[tokafr]

Hello.
I want to have a QTableView widget which will have a rounded corners. for that I create a class MyTableView which inherits QTableView and reimplement the paintEvent method. I do:

void MyTableView::paintEvent(QPaintEvent *event)
{
QTableView::paintEvent(event);

QPainter painter(this);

int radius = 6;

painter.setRenderHint(QPainter::Antialiasing);

QPen pen = painter.pen();

painter.setPen(Qt::NoPen);

painter.drawRoundedRect(rect().adjusted(1, 1, -1, -1), radius, radius,
Qt::AbsoluteSize);
painter.drawRoundedRect(rect().adjusted(1, 1, -1, -rect().height() + 10), 2, 2,
Qt::AbsoluteSize);

and I have:
[03.11.16 10:10:31.540] QPainter::begin: Widget painting can only begin as a result of a paintEvent
[03.11.16 10:10:31.540] QPainter::setRenderHint: Painter must be active to set rendering hints
[03.11.16 10:10:31.540] QPainter::pen: Painter not active
[03.11.16 10:10:31.540] QPainter::setPen: Painter not active
[03.11.16 10:10:31.540] QPainter::setBrush: Painter not active
[03.11.16 10:10:31.540] QPainter::setPen: Painter not active
[03.11.16 10:10:31.544] QPainter::begin: Widget painting can only begin as a result of a paintEvent

[03.11.16 10:10:31.545] QPainter::pen: Painter not active

what am I doing wrong? thank you.

You can use: QPainter painter(this->viewport());

Ok I found the answer. I added
setAttribute(Qt::WA_PaintOutsidePaintEvent, true);
flag to the widget I am repainting
