Action at pressing the key on certain line in jlist

Question

I dont understand how to delete the line of JList wich is pressed by delete-key. I know that it sounds like "write for me the code please" but.... it is) Because i dont know is it possible to determine the actual line and then make it answer to my actions.

I started to write something like that

list.addKeyListener(new KeyAdapter() {
    public void keyReleased(KeyEvent e) {
        if(KeyEvent.getKeyText(e.getKeyCode()).equals("Delete")) {
             // removing    
        }

    }

});

but how to proceed i have no idea

Answer 1

Assuming you are using a DefaultListModel and assuming you want to delete all the selected items, the code you need is

list.addKeyListener(new KeyAdapter() {
    public void keyReleased(KeyEvent e) {
        if(KeyEvent.getKeyText(e.getKeyCode()).equals("Delete")) {
            // removing:
            DefaultListModel lm = (DefaultListModel) list.getModel();
            for(int i : list.getSelectedIndices()) {
                lm.remove(i);
            }
        }
    }
});

otherwise:

• if you don't want to remove all the selected items I didn't understand your question :(
• if you're not using a DefaultListModel you have to extend the JList class or (better) create your own implementation of ListModel and create your own remove method...
