Simple DIY Scala DSL for javax.swing.SwingWorker

swingworkerdsl.scala

object Async {
  def async[A](thunk: => A)(whenDone: A => Unit) {
    val swingWorker = new javax.swing.SwingWorker[A, Any] {
      override def doInBackground(): A = thunk
      override def done(): Unit = whenDone(get)
    }
    swingWorker.execute()
  }
}

// Usage example
Async.async(recreateModel filter matches) { filteredModel => 
  tree.model = filteredModel
  tree expandRow 0
  tree.revalidate()
  tree.repaint()
}
