[vtkusers] QVTKWidget paintEvent

[Leonardo M. Ramé]

Hi, can paint over a QVTKWidget, however my drawings are lost when I
click on the widget or after setting a vtkImageViewer2 into it.

This is the code I use to paint over the QVTKWidget:

QPaintEngine * myWidget::paintEngine() const
{
  return QWidget::paintEngine();
}

void myWidget::paintEvent(QPaintEvent * e)
{
  QVTKWidget::paintEvent(e);
  QPainter paint(this);
  paint.setPen(Qt::white);
  paint.drawRect(5,5,10,10);
}

How can I let my drawings repaint over the image viewer
