want to create an dropdown menu in popup.

Question

This code that i taken from here is now workig for me .great now i want to create one autocomplete dropdown menu in it .so can u please help me out on this.

class PopupMenu extends Component
{
  override lazy val peer : JPopupMenu = new JPopupMenu

  def add(item:MenuItem) : Unit = { peer.add(item.peer) }
  def setVisible(visible:Boolean) : Unit = { peer.setVisible(visible) }
  /* Create any other peer methods here */
}

Then you can use it like this:

val item = new MenuItem(new Action("Say Hello") {
  def apply = println("Hello World");
})

val popup = new PopupMenu
popup.add(item)
popup.setVisible(true)

As an alternative, you could try SQUIB (Scala's Quirky User Interface Builder). With SQUIB, the above code becomes:

popup(
  contents(
    menuitem(
      'text -> "Say Hello",
      actionPerformed(
        println("Hello World!")
      )
    )
  )
).setVisible(true)
