Hello world, in Lanterna 3

HelloLanterna3.scala

import com.googlecode.lanterna.TextColor
import com.googlecode.lanterna.gui2._
import com.googlecode.lanterna.screen.Screen
import com.googlecode.lanterna.screen.TerminalScreen
import com.googlecode.lanterna.terminal.DefaultTerminalFactory

object Main {
  def main(args:Array[String]) = {
    val terminalFactory = new DefaultTerminalFactory
    terminalFactory.setSuppressSwingTerminalFrame(true)
    val terminal = terminalFactory.createTerminal()
    val screen = new TerminalScreen(terminal)
    val gui =
        new MultiWindowTextGUI(screen, new DefaultWindowManager(), new EmptySpace(TextColor.ANSI.BLUE))

    screen.startScreen()
    gui.addWindowAndWait(new BasicWindow("Hello, world!") { window ⇒
        setComponent(new Panel() {
          addComponent(new Label("Welcome to Lanterna!"))
          addComponent(new Button("Quit", new Runnable {
            override def run(): Unit = {
              println("Quit pressed! Exiting...")
              window.close()
            }
          }))
      })
    })
    screen.stopScreen()
    println("Application finished!")
  }
}

I think setSuppresSwingTerminalFrame is deprecated in favour of setForceTextTerminal?
