Hi
Now I've tried for a few days to make an interface which takes the
text of a button and adds it to a JLabel. It is also partly succeed -
When I println the information to the prompt about the JLabel after
pressing a button it shows me the right updated JLabel text, but in
the GUI the JLabel have not been updated. It shows the text from the
begining.

The code is below! It is placed on a JLayered defined in a nother
class file. Sorry if the code is a bit strange, I haven't made that
much Java programming before. First I've made the text change in the
actionlistener but that didn't work so I tried to make a function to
update the JLabel as seen below. What could be wrong in both cases.
Changing the JLabel in the actionlistener and/or in the class file
should both be possible right?!

Thanks in advance.
