Joe,
in addition :
- you can write your own classes in more than one .prg : for example one
.prg for all your standard classes ('standard_joe.prg'), a second one
with all the classes linked to a particular app (standard_myapp.prg)
(and these classes can be instances of classes in standard_joe)
- try to built a 'hierarchy' : first just build a subclass of textbox,
let's say textbox_joe without any new property or method; second build
numerical_textbox based on textbox_joe with some properties and methods
dealing with numbers; then your numerical_plus_textbox based on
numerical_textbox in wich you will add the properties and methods to
manage your '+', and calculator, ... In some days you will have to build
a "telephone_textbox" to deal with telephone numbers, a 'zip_textbox', ....
Very quickly, you will see that you build a lot of classes, and having
them well 'sorted' is very important.
