Why it won't work:
1. The two mouse clicks are two separate events
2. Event 1 calls your fireActionPerformed, which disables the button, calls
the real fireActionPerformed, then enables the button again.
3. Event 2 still causes things to happen, because the events are stored in a
queue, acted on in order.. So by the time the system comes to process event
2, the last bit of event 1 has re-enabled the button.
(Please correct me if I am inaccurate with that.)
How it might work depends on what happens as a result of pressing the
button. For example, say it shows a frame. Get your listener to detect when
the frame is opened and closed. Don't allow more frames to be opened if
there is one open already.

Subject: Button multiple "fireActionPerformed"
Hi list,
I appologize if the question has already been asked and answered. It
seems to be very simple but I can't figure out how to do it.
I have a JButton with an action listener registered. The goal is to
prevent a "multiple click" on the button to multiply the
"fireActionPerformed".
My first idea was to override the fireActionPerformed method to first
disable the button, really fireActionPerformed and then re-enable the
button. This doesn't work since the multiple cliks seem to be forwarded to
the eventDispatchThread before the button gets disabled.
Did any one ever solve this problem ?
Thanks for all your answers.
Vincent.
