[vtkusers] Using QTPainter with QVTKWidget

[Anja Ende]

Hi everyone,

Has anyone been able to successfully use QPainter methods in QVTKWidget.

So, I have derived a class from QVTKWidget and override the paintEvent
method as follows:

void QTVTKWidget::paintEvent( QPaintEvent * event)
{
            QVTKWidget::paintEvent(event);
            QPainter painter(this);
            ....
}

This however,  returns a run time error as in it could not create the
painter object. The error is:

Painter::begin(), paintdevice returned engine == 0, type: 1

Just wondering if someone has been able to use this successfully.


Cheers,

Anja
