Swing 单击按钮时缩放打开的框架

我正在用scala创建一个应用程序。我想在点击按钮时打开一个框架。我是斯卡拉的新手。这是密码

 import scala.swing._;
 import java.io._;
 import scala.swing.event._;
 import javax.swing.ImageIcon;

object Try1 extends SimpleSwingApplication {
def top = new MainFrame {
title = "First Swing App";

val button = new Button {
  text = "Proceed"
}
contents = new BoxPanel(Orientation.Vertical) {


  contents += button

  border = Swing.EmptyBorder(30, 30, 30, 30)
}
val obj = new Try2();
listenTo(button)

reactions += {
  case ButtonClicked(button) =>
   //here 2nd frame must be open

 }
}

要打开的窗口的代码如下所示

import javax.swing.ImageIcon
import scala.swing._

class Try2 extends SimpleSwingApplication {
 def top = new MainFrame {
 title = "Second Swing App";

val button = new Button {
  text = "Proceed"
}
contents = new BoxPanel(Orientation.Vertical) {


  contents += button

  border = Swing.EmptyBorder(30, 30, 30, 30)
    }
  }
}

我怎样才能打开新窗口。请帮助

您可以执行如下所示的操作。这里我有意创建一个新的Try2实例，而不是先前创建的

obj

，因为这是一种更干净的方法

reactions += {
  case ButtonClicked(x: Button) if x.text == "Proceed"  =>
    new Try2().top.visible = true
}

谢谢你救了我一天
