public void change(int number) { try {Thread.sleep(300);} catch (InterruptedException e) {} mybutton[number].setIcon(down[number]); try {Thread.sleep(500);} catch (InterruptedException e) {} mybutton[number].setIcon(up[number]); } When i call this method from my Contructor it works fine, but when i call it from Actionperformed, it won't sleep! I found out that when i call it and it works the thread's name is "Thread[main,5,main]", but when i call it from actionperformed it's "Thread[AWT-EventQueue-o,6,main]". What i want to do: Have one    More>>
public void change(int number)

{

try {Thread.sleep(300);} catch (InterruptedException e) {}

mybutton[number].setIcon(down[number]);

try {Thread.sleep(500);} catch (InterruptedException e) {}

mybutton[number].setIcon(up[number]);

}




When i call this method from my Contructor it works fine, but when i call it
from Actionperformed, it won't sleep!



I found out that when i call it and it works the thread's name is
"Thread[main,5,main]", but when i call it from actionperformed it's
"Thread[AWT-EventQueue-o,6,main]".



What i want to do:

Have one of my JButtons change ImageIcon for 0,5 seconds
when i press on it!



The Problem:

The thread won't sleep when i call it from actionperformed.

Ps. I have no such things like "Run()" or "new Thread" or something like that in my code.    <<Less

    ...
    public void actionPerformed(ActionEvent e)
    {
        // when you are ready to call the change method
        SwingUtilities.invokeLater(new Runnable()
        {
            public void run()
            {
                change(myNumber);
            }
        });
    }

Do a repaint() on the mybutton after each setIcon ... or maybe an invalidate(). Such things usually get it to work.

I recall somewhere in my memory that the action events have a single thread of execution and that you should use the SwingUtilities for threads in event handlers....sorry that's all I can remember but maybe it'll point in the right direction...
