Ah OK. Somehow I missed that.
So does that mean that basically the only way to set, say, the pen's colour to red is with the following statement?

Qt Code:

Switch view

myRect->setPen(QPen(Qt::red));

myRect->setPen(QPen(Qt::red));

To copy to clipboard, switch view to plain text mode

Indeed. I would say that *that* is the bigger problem, i.e., Qt apparently (?) didn't tell you that you were attempting to change a const variable.

Well there's no warning during compilation, or error while running, but the pen colour doesn't change, so I'm not sure exactly what's going on.
