Multiple selection in JList

Question

How can I set up a JList that always uses multiple selection. That is, it acts as though the CTRL key is held down when the user selects items.

Answer 1

Here's an example of multi-selection in a listbox, but using the shift key
import java.awt.*;
import java.awt.event.*;
import java.net.*;
import java.applet.*;
public class Multi extends Applet implements KeyListener
     List list = new List(5, true);
     public void init()
          createGUI();
          setSize(300,300);
          this.setVisible(true);
     public void createGUI()
          for (int j = 0; j < 20; j++)
               list.addItem("TESTING MULTI-SELECTION IN A LIST");
          add (list);
          list.addKeyListener(this);
     public void keyReleased(KeyEvent e)
          int key = e.getKeyCode();
          if (key == KeyEvent.VK_SHIFT)
               int itm[] = list.getSelectedIndexes();
               for(int i = itm[0]; i < itm[1]; i++)
                    list.select(i);
     public void keyTyped(KeyEvent e){}
     public void keyPressed(KeyEvent e){}
}
