[Qt-interest] Widget for floating point number input?

[Rui Maciel]

What widget do you use to input floating point numbers?  I'm having trouble discovering a 
widget that handles floating point input well.  QSpinBox only deals with ints, QDoubleSpinBox 
is terribly limited (doesn't accept values greater than 10^10-1) and QLineEdit and it's mask 
is terribly restrictive.  

So, what widget do you use?


Thanks in advance,
