Painter not active

[tommyfuu]

Hi,

I was generating a tree, and got the following error:

QPainter::setWorldTransform: Painter not active
QPainter::save: Painter not active
QPainter::setOpacity: Painter not active

I am writing a tree class for specific functionalities. My functions seem to work most of the time, but when it attempts to generate files bigger than a certain size, it will get the above error. I wonder if anyone else has run into it?
