将鼠标侦听器添加到ListCellRenderer中的JLabel

Question

I have a ListCellRenderer that consist of two JLabels; one for text and one for an exit image (a little cross).

I want to add a mouselistener to that little cross, when clicked, the item is removed from the JList.

Answer 1

You can try adding MouseListener to your JList directly as follows,

list.addMouseListener(new MouseAdapter(){
   public void mouseReleased(final MouseEvent e) {
         if (e.isPopupTrigger()) {               

             // Get the position of the click
              final int x = e.getX();
              final int y = e.getY();

              // Verify that the click occured on the selected cell
              final int index = list.getSelectedIndex();
          }
    }
});

Now depending on index above you can achieve what you want to do.
