[Qt-interest] Qtree widget + memory fault

[NARCISO, Rui]

Hi all,

I have a Qtreewidget.
I connected a Qtimer to a function that changes the colors of my lines every second (blinking effect).

Now, the problem (described below), occurs when I try to had new elements to the tree while it is changing the colors.

Does anyone know how I can stop this from happening ?
