I have a problem that sick me from much time;
When my application starts, starts 3 updateWidget and 3 initializeGL() (with a qglwidget)without reason;
I understand the cause is the toolbox; If I delete it in Designer this behavius there isn't;
I think that is happening: application draw the entire widgetGL (using entire width of mainForm), after insert toolboox, and then must re-paint() because the width is grow down;
is it possible? Why do I resolve it?
