I think I understood,
next time I will use the GUI Designer, but a freind of mine told me about
some difficulties with it, so i first tried without.

Could you (to be shure if I understood you right, just put your code in
mine, so that I find out what you meant by the initWith mehtod. In which
class would you implement it?

Thanks Thomas
