[Qt-interest] Paint Device

[Nat - Not]

Hi there,

I'm going to make a project of creating some maps from some files(Most of
the time I will use QPaint and images).Context is not relevant though.
This project is going to be a kind of gui library (dll,so,etc..).Performance
and the smallness of the file is important.So instead of using QWidget I
wonder if I could(should) use QPaintDevice?

If yes,how?

I checked the source code of QWidget to see how the paint event starts,yet I
wasn't quite successful to understand.

Thanks in advance.
