I have made a derived class of Fl_Input that uses a template to control what and where chars ate typed in. This saves the need for a callback to check the validity of the data input. Good for things like phone numbers, mac address and any thing else that needs to conform to a given format.
If the user types in a char that is not suitable for the string[], the keypress is ignored.
