[Qt-creator] Drawing on QWidget

[Patrick Scheller]

I fully agree with you Alex, even though there is a lot of good  
documentation around for Qt, there are still some blind spots where  
you risk to being stuck for a long time because certain relations  
aren't obvious enough to the average programmer. I for example bought  
2 Qt books and still couldn't find more than some basic info about  
how to work with generated code from the designer. André sees things  
from the perspective of the maker (developer) of Qt and Qt-Creator  
which explains his usual RTFM or RTFC attitude - for him there is no  
other way to approach a program or an API. We cannot blame him, I  
work with many guys that have the same attitude. :)
But I'm sure he is otherwise a really brilliant and sharp mind and  
coder!

So pls André take no offence in my words. :D

And thanks Alex for persisting, this topic was most interesting for  
me too.
