Hi Lino,
This is basic C++,
You have a mismatch between the types used in the
definition of the SetOperandA() method and its
invocation.
>: 'SetOperandA' : cannot convert parameter 1
> from 'int (double)' to 'float'
The definition of the types in your base class
do not match the ones in CalculatorGUI.
---
The other errors are due to missing include FLTK
headers.
--
Please send me the full set of files that
you are putting together for this basic demo.
It will be faster than solving error by error
in the users list.
Thanks
Luis
