I have created a swings application and there is a "Start" button on the GUI. I want that whenever I clicked on that "Start" button, the start button should be disabled and the "Stop" button be enabled.

For that I have written the following code in the "ActionPeformed(...)" method of the "Start" button

startButton.setEnabled(false);
stopButton.setEnabled(true);

But the above code is not creating the desired affect on the GUI.

Is the above code correct for what I want to do?

It's not working with "repaint()" too.

Edit:

The code is very long so I can't paste all the code. I can tell, though, more about the code.

In the "ActionPeformed" method of "start" button, after calling the above two statements, I am executing a "SwingWorker" thread.

Is this thread creating any problem?

java user-interface jbutton
