Poor man's growl-like notification on windows

notification.scala

import java.awt.TrayIcon
import java.awt.SystemTray.{getSystemTray => tray}
import java.awt.Toolkit.{getDefaultToolkit => toolkit}
import java.net.URL

object Notification {
  private lazy val scalaIcon = {
    // of course we use the logo of our favorite language ;)
    val img = toolkit.getImage(new URL("http://www.scala-lang.org/sites/default/files/favicon.gif"))
    new TrayIcon(img)
  }

  def show(caption: String, text: String, messageType: TrayIcon.MessageType = TrayIcon.MessageType.INFO, icon: TrayIcon = scalaIcon) {
    tray.add(icon)
    icon.displayMessage(caption, text, messageType)

    // On windows, the message balloon is removed, as soon as the icon is removed. That's why we just wait couple of seconds here.
    Thread.sleep(5000)

    tray.remove(icon)
  }
}

Notification.show("foo", "bar")
