如何使用Groovy SwingBuilder创建JDesktopPand/JInternalFrame组合体？

Question

我正在尝试使用SwingBuilder创建一个Groovy应用程序。

我从http://groovy-lang.org/swing.html的基本http://groovy-lang.org/swing.html示例开始，并添加了对desktopPane和internalFrame的调用

import groovy.swing.SwingBuilder
import java.awt.BorderLayout as BL

count = 0
new SwingBuilder().edt {
  frame(title: 'Frame', size: [300, 300], show: true) {
    desktopPane() {
      internalFrame() {
        borderLayout()
        textlabel = label(text: 'Click the button!', constraints: BL.NORTH)
        button(text:'Click Me',
             actionPerformed: {count++; textlabel.text = "Clicked ${count} time(s)."; println "clicked"}, constraints:BL.SOUTH)
      }
    }
  }
}

但是，这段代码只为我提供了一个空白窗口。

看来我只需要将visible和bounds参数添加到internalFrame

import groovy.swing.SwingBuilder
import java.awt.BorderLayout as BL

count = 0
new SwingBuilder().edt {
  frame(title: 'Frame', size: [300, 300], show: true) {
    desktopPane() {
      internalFrame(visible: true, bounds: [25, 25, 200, 100]) {
        borderLayout()
        textlabel = label(text: 'Click the button!', constraints: BL.NORTH)
        button(text:'Click Me',
             actionPerformed: {count++; textlabel.text = "Clicked ${count} time(s)."; println "clicked"}, constraints:BL.SOUTH)
      }
    }
  }
}
