How to block action events?

Question

Hi,
how can i block an event call from GUI?
Imagine i have a button on a page.
The click on this button call an action listener "buttonClicked".
I want to call this action listener only in the first click.
Then, while this method do something, the next clicks on this button do not call the action listener.
So, after the method ends his execution, i enable the button clicks again.
Is there any way to do that?
Thanks.

I don't know if this is the best solution, but what I did was to pass the components as arguments in the action listener classes. Every time you invoke an action listener for component A that needs to influence component B, pass component B as an argument to a custom setComponentB(componentB) method in B's action listener.
Here's an example of my code that deals with this. The code implements a database search that displays the results as a list in a scrollable window.
class MainGUI
public static void main (String [] args)
JButton searchButton = new JButton();
JList resultList = new JList();
JScrollPane sp = new JScrollPane(resultList);
SearchButtonListener sbl = new SearchButtonListener();
sbl.setTarget(resultList);
searchButton.addActionListener(sbl);
class SearchButtonListener implements ActionListener
private JList target;
void setTarget(JList target)
this.target = target;
public void actionPerformed(ActionEvent e)
// perform database search and store results in Vector resultVector
target.setListData(resultVector);
Hope this helps.
