[vtkusers] QVTKWidget paintEvent

[Leonardo M. Ramé]

Thanks for answering Sam, indeed, all the drawing is in my paintEvent:

void DCMWidget::paintEvent(QPaintEvent * e)
{
  if(m_selected)
  {
    QPainter paint(this);
    paint.setPen(Qt::white);
    paint.drawRect(5,5, this->width()-10, this->height()-10);
  }
}

Could you show me an example of what you suggest?.
