Hello!

I'm creating a text-mode gui library.
This is my idea: class Layer with size, style and event handlers like
onPaint, etc., and a vector of Layer* to hold its sublayers (for examle:
MessageBox has a border and an "OK" button). Every widget - like Label,
Border, etc. - will inherit from Layer and extend it as needed. In main
header file I added an object of class Layer called "screen", so that
the user will use it to add components to the program.

Adding elements is easy and looks like this:
screen->add(new Label("Hello World!"));

The problem is, how do I access this Label's properties? Is it possible
to do it without casting (if not, it's a poor library if you have to use
casting every now and then, IMHO)?

Thanks in advance.
