Hello,

i have two classes. With class A i can calculate some things on the
console. In class A i create an object of class B. In B a JFrame with a
canvas is designed, where i paint some things. So far all works fine.

Now my problem: After every calculation on the console i want to
refresh the JFrame somehow, in order to repaint the canvas.
myObject.repaint() does not return an error but does not work.

Is there a solution?

Thanks in advance and greetings,
Bastian
