This should be Qt::DoubleValidator.new - perhaps thats the problem. It looks 
as though it should be ok apart from that. 

But I only fixed mutable string args in method calls being correctly updated 
after the call recently, so you might need the most recent QtRuby version in 
the cvs. If it doesn't work, maybe could you post complete example code to 
make any problems easier to reproduce?

Yes, all the Qt classes are renamed without the initial Q, so Qt::LineEdit is 
correct.
