Answer 1

If you’re wondering how to add a JSpinner to a Scala swing application, you need to use Component.wrap(JComponent) to get a Scala component. This should give you something to model on:

import swing._

import javax.swing.SpinnerListModel
import javax.swing.JSpinner

object SpinnerDemo extends SimpleSwingApplication {
  val monthStrings: Array[Object] = Array("January", "February", "March",
    "April", "May", "June", "July",
    "August", "September", "October",
    "November", "December")

  def top = new MainFrame {
    title = "Spinner Demo"

    val monthModel = new SpinnerListModel(monthStrings)
    val spinner = new JSpinner(monthModel)
    contents = new FlowPanel {
      contents += new Label("Month")
      contents += Component.wrap(spinner)
    }
  }
}
