Java-在JPanel中单击的组件

Question

I have a JList<JPanel> that includes a JCheckBox and JLabel . I need to find out which one was clicked. I am using a MouseAdapter . I can get the JPanel with

int index = locationToIndex(e.getPoint());
getModel().getElementAt(index);

But I can't find a way to determine what Component in the JPanel was clicked.

Any help is appreciated.

Call JList.addListSelectionListener(ListSelectionListener) .

The ListSelectionListener provides a ListSelectionEvent . See the methods of the event to get access to the 1st and last indices of the user's selection. See also How to Use Lists in the tutorials for further tips & working source.
