Scala Swing 中的微调器

Question

如何做到这一点： http://download.oracle.com/javase/tutorial/uiswing/components /spinner.html 使用： http://www.scala-lang.org/api/当前/index.html#package ？

Answer 1

如果您想知道如何将 JSpinner 添加到 Scala swing 应用程序，则需要使用 Component.wrap(JComponent) 来获取 Scala 组件。这应该给你一些可以借鉴的东西：

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)
    }
  }
}

Answer 2

这并不容易。

[error] /home/ciembor/projekty/VirtualCut/src/main/scala/View/View.scala:22: reference to Action is ambiguous;
[error] it is imported twice in the same scope by
[error] import javax.swing._
[error] and import swing._

swing 和 javax.swing 是冲突的。我想我应该只导入 JSpinner 类。
