I have a QValidator-derived class assigned to my QLineEdit that can determine the status of the input, but what is the "right" way to get the QLineEdit to change font color based upon this status?
Sean already gave you the answer on how to do it at the moment. It would 
be very cool if you could simply use a stylesheet to do it using a set 
of pseudo states. I suggested that in the bugtracker quite a while ago, 
but I doubt it will get implemented. It would make this kind of thing 
trivial though...
