Scala property bindings

This library provides property bindings similar to Qt signal slot system, JavaFx's properties and other.

示例程序：

private class Model {

  val text = new Observable("count: 0")

  private var count = 

  def increment() {

    count += 1

    text() = "count: " + count

  }

}



object Example extends SimpleSwingApplication {

  private val model = new Model



  def top = new MainFrame {

    title = "Example"

    contents = new GridPanel(2, 1) {

      val button = new Button("Press Me!")

      contents += button



      val label = new Label {

        text = observes(model.text, text_=)

      }

      contents += label



      listenTo(button)

      reactions += {

        case ButtonClicked(_) => model.increment()

      }

    }

  }

}
