[Qt-interest] Custom QTreeView header

[Fabio Dago]

Hi.

I'm trying to create a custom header for QTreeView.

The QHeaderView documentation says that using a delegate for custom 
painting has no effect, so I subclass QHeaderView and reimplement 
paintEvent()...

void MyHeaderView::paintEvent(QPaintEvent* e)
{
     QPainter painter(this);
     //...
     //...
}

I dont't know why, but this doesn't work, and the QPainter contructor 
outputs: " QPainter::begin: Paint device returned engine == 0, type: 1 "

What's wrong?

Thanks.
Fabio.
