Removing MouseListener() from a JLabel

问题

I added a MouseListener to a JLabel. Now if I want to disable this MouseListener associated with the JLabel, when the label is clicked once, how can I do it.

I know there is a big way to set a boolean or int variable when the label is clicked and then call a method and remove MouseListener there, but I want to learn a compact and easy way. Is there a way to do this?

回答1:

In your mouse listener:

public void mouseClicked(MouseEvent event) {
    // Do stuff...
    ((Component) event.getSource()).removeMouseListener(this);
}

回答2:

What's wrong with label.removeMouseListener(listener)? It works just fine. If you want to create listener that removes itself call label.removeMouseListener(this)
