[lazarus] Notebk example

[Micha Nelissen]

Hi,

The Notebk example now works correctly on my machine with the exception 
did I had to change Width,Height initialization in the example. The 
example uses Parent.{Width|Height} but these are 0 in win32. Is this the 
case also with GTK? (It causes the nested notebook to disappear.) I 
guess not...but seen the fact that no window handles are made yet, the 
interface hasn't done very much yet. Could someone check my statements here?

Thanks,

Micha.
