the problem is, that if I want to override the onPaint-method, I have to set
the user-Bite for user-controlled-painting like this:
this.SetStyle(System.Windows.Forms.ControlStyles.UserPaint, true);

If I did so, it seems that the DrawItem-Event will not be fired any more, so
that the tabs of my tabControl won't be visible. They still exist because I
can switch the TabPages, but they have the same color as I set it for my
TabControl.

If I don't set the user-bite in the described way the Color of my TabControl
won't be changed.

I don't know how to solve this problem. Maybe I have to throw the
DrawItem-Event for myself, but where and in which way?
