Re: Parsing custom-typed properties from Glade file

[N <nicklas karlsson17 gmail com>]

Enums are very useful for selection, combobox. I have selections and parse the number in the combox, this 
does not feel ideal.

In C with switch(...) and correct warning turned on compiler flag a warning in case a value is forgotten, I 
trick I often used to remember all cases but only work then enumerations are known at compile time. As a 
bonus work get easier for computer with numbers instead of text strings.

As I only handle types known at compile time glade file should then correct done have these and only these 
enumerations, an exact mapping. To check these agree is also an interesting problem.
