Adding ActionListener to JPanel or equivalent
Hi all.
I am trying to add an actionListener for mouse clicks on a JPanel, ideally using something like this:
panel.addActionListener(new ActionListener(){
publicvoid actionPerformed(ActionEvent e)
{
//do something
}
});
However, JPanel does not implement addActionListener, and as far as I can see the only components which do are buttons, radio buttons and the like.
I tried extending JPanel to implement ActionListener, but had no success.
Is there an easy way to monitor for mouse clicks on a JPanel or container? Bearing in mind there will be several of these containers at different locations, so using a global mouse listener would not be useful.
Thanks

Use a MouseListener.

So add individual MouseListeners to each container.

Thanks for the quick reply, had totally missed that possibility.
For anyone else interested, here's what I used:
class MouseListen extends MouseAdapter
{
public void mouseClicked(MouseEvent e)
{
//event code
}
}
panel.addMouseListener(new MouseListen());
Extending MouseAdapter means you need not implement all the MouseListener methods.
