tSR GameDev Tutorials: Qt C++ - Sprite Drawing

[Asther]

I tried this a while ago, but delayed posting hoping some one else might ask. Guess not?

I created a new project as your instructions said, but in the header file I can't find the changeEvent function or any function and I don't know where to put the paintevent function.

I tried entering the paintevent function anyway, under "public", and it gave me some issues.
on
QPainter painter(this);
it says "variable 'Qpainter painter' has initializer but incomplete type."

dont get why no one else has posted about this
