Detailed Description

The Input Line class implements a rectangular are where user can enter any text.

The class has a method called IsValidChar() which can be overriden to implement specific needs, for example if you would like to implement a input line which accepts only numbers you can just override the method IsValidChar() and analyze entered characters. There is also a more general method called IsValidString() which checks the just-modified string for correctness. If method decides that string is incorrect, the changes are undone.
