ok i c...maybe i overreacted. and yes i have way more theoretical knowledge than practical. as a mathematician i did a lot of programming in matlab and algorithms, loops, branches and so an are not the problem. maybe i want too much for now...
i am aware of the fact that i may be doing things at the moment which aren't necessarily done that way. i don't know. i do it this way to learn something about this specific language and how it works. so first i did was playing around with classes and inheritance, learning how constructors work, how to overload, and so on...doing a little bit of GUI to see if my expectations are met.
well...i will start as jps said with a textfield
that shouldn't be the bigger problem. maybe something that manipulates a string and gives back the manipulated string.
started reading the GUI tutorial ^^
thanks you 2
