Note : Thanks for someone that show me some light. It is wrong when we want to add component into JWindow like example(For example : window is variable for JWindow, it wrong when we want to add component into JWindow...we do like this window.add(button)).We must get it's container first, and after that we will add component into JWindow using container that we get.You can see source code above after i repaired it.
