How to stop user from generating more events?

I am developing a java swing desktop application. The dialog form has an ok and cancel button. When the user clicks ok button the application does some processing. How can I stop user from clicking ok again before the event on ok button has finished executing. Also, i dont want the user to able to press the cancel button till ok has finished executed. Any help will be highly appreciated.

Enablement management is an integral part of UI logic. Action helps you doing so:

 Action action = new AbstractAction("myAction") {

      public void actionPerformed(ActionEvent e) {
           setEnabled(false);
           doPerform();
           setEnabled(true);
      }
 };
 button.setAction(action);

Beware: long running task must not be executed on the EDT, so this is for short-term only, to prevent the second or so click having an effect

Edit

just noticed that you tagged the question with jsr296, then it's even easier: you can tag a method of your presentation model as @Action and bind its enabled property to a property of the model

@Action (enabledProperty == "idle")
public void processOk() {
    setIdle(false);
    doStuff;
    setIdle(true);
}

Plus there is support (much debated, but useable) for Tasks: basically SwingWorker with fine-grained beanified life-cycle support

If you want to disable all the controls, then I'd suggest using a GlassPane. See here for more info: http://docs.oracle.com/javase/tutorial/uiswing/components/rootpane.html

It seems that what you want is something like a waiting cursor.

You can disable your button like yourButton.setEnabled(false); during your processing method and enable it again when it finishes.

The easiest way is to disable the button just after clicking it , and when the action performed is complete then re-enable it.
