I have a JLabel in a JPanel in a JScrollPane. I want to add a MouseListener to the JLabel, but it's not working.
I can add a MouseListener to the JScrollPane, but not the JLabel for some reason. Help!
the code is basically:
JPanel scrollPanel = new JPanel();
ScrollLabel scrollLabel = new ScrollLabel();
ScrollPanel.add(scrollLabel);
JScrollPane scrollpane = new JScrollPane(scrollPanel);
class ScrollLabel extends JLabel implements MouseListener{
public void mousePressed(MouseEvent e) {}
public void mouseReleased(MouseEvent e) { }
public void mouseEntered(MouseEvent e) {}
public void mouseExited(MouseEvent e) {}
public void mouseClicked(MouseEvent e) {}
}
try this:
class ScrollLabel extends JLabel implements MouseListener{
public ScrollLabel(){
addMouseListener(this);
}
public void mousePressed(MouseEvent e) {}
public void mouseReleased(MouseEvent e) { }
public void mouseEntered(MouseEvent e) {}
public void mouseExited(MouseEvent e) {}
public void mouseClicked(MouseEvent e) {}
}
Why are you subclassing JLabel just to add a mouselistener? That is not necessary. Why not just add an anonymous listener like so:
JLabel scrollLabel = new JLabel("My ScrollLabel");
scrollLabel.addMouseListener(new MouseListener()
{
public void mouseClicked(MouseEvent arg0)
{
// TODO do stuff here
}
public void mouseEntered(MouseEvent arg0){}
public void mouseExited(MouseEvent arg0){}
public void mousePressed(MouseEvent arg0) {}
public void mouseReleased(MouseEvent arg0) {}
});
Or you can add a non-anonymous inner class type listener:
{
JLabel scrollLabel = new JLabel("My ScrollLabel");
scrollLabel.addMouseListener(new myMouseListener())
}
class myMouseListener implements MouseListener
{
public void mouseClicked(MouseEvent arg0)
{
// TODO do stuff here
}
public void mouseEntered(MouseEvent arg0){}
public void mouseExited(MouseEvent arg0){}
public void mousePressed(MouseEvent arg0) {}
public void mouseReleased(MouseEvent arg0) {}
}
