如何在构建面板后动态地将按钮组添加到面板

Question

我正在使用Groovy Swingbuilder，并且想要在初始面板构建完成后动态填充单选按钮 - buttongroup。例如：我有一个有几个选项的面板。根据选择哪个选项，我需要用一组单选按钮填充按钮组。每个选项的收音机选项都不相同。

我的面板会是这个样子：

panel(id:"chooseClass", visible:true, layout: new BL()){ 
      vbox(constraints: BL.CENTER){ 
       label("Player Statistics", horizontalAlignment: 0) 
       label(id: 'raceLabel', text: raceLabelText, horizontalAlignment: 0) 
       label(id: 'statLabel', text: statLabelText, horizontalAlignment: 0) 
       panel(id:'classGroupPanel', layout: new GridLayout(1,9)){ 
        myButtonGroup = buttonGroup(id:'classGroup') 
       } 
      } 
     } 

再后来在我的代码我有这样的方法：

def void setClassGroup(){ 
    def classButtons = plyGen.getAvailibleClass() 
    // this is one way I've tried it 
      gPane.edt{panel(id:'classGroupPanel', layout: new GridLayout(1,9)){ 
     buttonGroup(id:'classGroup').with{ group -> 
      classButtonGroup.each{ radioButton(id: '${it.name}', CreateRadio("${it.name}"), mnemonic:"${it.mnenomic}", buttonGroup: group)}} 
    } 
    } 
      // and this is another way I've tried it 
    gPane.doOutside { 
     this.classGroupPanel{ 
     buttonGroup(id:'classGroup').with{group -> 
      classButtons.each{ gPane.radioButton(id: '${it.name}', CreateRadio("${it.name}"), mnemonic:"${it.mnenomic}", buttonGroup: myButtonGroup) } 
      } 

     } 
    }    


} 

这两种尝试编译和运行没有错误，但我不” t获取单选按钮列表。我希望有更多关于swingbuilder的文档。

失踪panel.revalidate()？这个家伙根据你选择的乐队显示一个单选按钮组。歌曲呈现为单选按钮：

import groovy.swing.* 
import javax.swing.* 
import java.awt.* 
import java.awt.BorderLayout as BL 

def drawSongsPanel(songs) { 
    def p 
    new SwingBuilder().edt { 
    p = panel(visible: true) { 
     vbox(constraints: BL.CENTER) { 
     buttonGroup().with { btn -> 
      songs.each { 
      radioButton text:it, buttonGroup: btn 
      } 
     } 
     } 
    } 
    } 
    p 
} 


def getSongs(band) { 
    switch (band) { 
    case "stones": return ['start me up', 'jumpin jack flash', 'satisfaction'] 
    case "beatles": return ['hey jude', 'yellow submarine', 'yesterday'] 
    } 
} 


def chooseBand(event, panelBands) { 
    panelBands.add drawSongsPanel(getSongs(event.actionCommand)) 
    panelBands.revalidate() 
} 


new SwingBuilder().edt { 
    frame(defaultCloseOperation: JFrame.EXIT_ON_CLOSE, visible: true, size: [600,500]) { 
    panel(visible: true, layout: new BL()) { 
     vbox(constraints: BL.CENTER){ 
     def panelBands 
     panelBands = panel(id:'classGroupPanel', layout: new GridLayout(1,9)) { 
      buttonGroup(id: 'classGroup').with { 
      radioButton text:"beatles", buttonGroup: it, actionPerformed:{e->chooseBand(e, panelBands)} 
      radioButton text:"stones", buttonGroup: it, actionPerformed:{e->chooseBand(e, panelBands)} 
      } 
     } 
     } 
    } 
    } 
}
