■ v2.10.1

    

        v2.10.1/src/swing/scala/swing/Component.scala
    
  object mouse {
    /**
     * Publishes clicks, presses and releases.
     */
    val clicks: Publisher = new LazyPublisher {
      lazy val l = new MouseListener {
        def mouseEntered(e: java.awt.event.MouseEvent) {}
        def mouseExited(e: java.awt.event.MouseEvent) {}
        def mouseClicked(e: java.awt.event.MouseEvent) {
          publish(new MouseClicked(e))
        }
        def mousePressed(e: java.awt.event.MouseEvent) {
          publish(new MousePressed(e))
        }
        def mouseReleased(e: java.awt.event.MouseEvent) {
          publish(new MouseReleased(e))
        }
      }

      def onFirstSubscribe() = peer.addMouseListener(l)
      def onLastUnsubscribe() = peer.removeMouseListener(l)
    }

• 新たに LazyPublisher が追加され、旧来の addMouseListener/removeMouseListener に代えて、今後は onFirstSubscribe/onLastUnsubscribe を利用することが望まれます。

■ v2.9.2

    

        v2.9.2/src/swing/scala/swing/Component.scala
    
  object mouse {
    val clicks: Publisher = new Publisher {
      peer.addMouseListener(new MouseListener {
        def mouseEntered(e: java.awt.event.MouseEvent) { }
        ...
      })
    }
