Hi Lino,
Thanks for sending your files.
Here are the problems with your code:
1) You were passing
o->value
instead of
0->value()
"value" is a FLTK method for the
valuators Widgets. When you return
the name of a function without "()"
you are passing the pointer to the
function instead of its return value.
2) In the window widget in the fluid
file, you were defining the window
to be of class "CalculatorGUI".
That's incorrect, you don't need to
change the type of the widget.
3) The signatures of the BaseCalculator
types were 'float', while the return
types of FLTK valuator is 'double'.
Please find attached the files that are
working fine.
Regards,
Luis
