After some further playing around with the tetrix example I have found another 
fairly minor issue which picks up on some points made later in this thread. 
There are some functions in the QPainter class which have a const QBrush 
argument but which can take a QColor due to an implicit QBrush(color) 
conversion. They all seem to work with the exception of this one:

	QPainter.fillRect(int x,int y,int w,int h,const QBrush & brush) 

When passed a QColor, this fails with "TypeError: argument 5 of 
QPainter.fillRect() has an invalid type" followed by a segmentation fault 
(sometimes). Of course, this can be cured with an explicit conversion.

(NB: I also back-ported the tetrix example to Qt3 and got the same error).
