使用container（）在SwingBuilder中添加JSplitPane的自定义子类会导致IllegalArgumentException

时间：2012-03-16 05:42:30

标签： groovy swingbuilder

我是groovy和griffon的新手，目前在SwingBuilder上玩一下。我想添加一个JSplitPane的子类（它使用http://www.formdev.com/blog/swing-tip-jsplitpane-with-zero-size-divider/中描述的细分隔符。）

您可以在下面找到视图定义脚本。我使用了一个容器（） - 元素来添加我的Splitpane-subclass。当我启动我的应用程序时，我得到一个java.lang.IllegalArgumentException。任何想法如何解决这一问题？

视图：

frame(id:"frame",
 title: 'The new database explorer implemented with groovy/griffon',
 size: [600, 400],
 locationByPlatform:true,
 iconImage: imageIcon('/griffon-icon-48x48.png').image,
 iconImages: [imageIcon('/griffon-icon-48x48.png').image,
              imageIcon('/griffon-icon-32x32.png').image,
              imageIcon('/griffon-icon-16x16.png').image]) {

   panel (id:'mainPanel',
           opaque:false) {
       borderLayout()
       toolBar(id:'toolBar',
               constraints:NORTH,
               floatable:false,
               opaque: false,
               preferredSize: new Dimension(200,50)) {
           hglue()
           textField(id:'search', "clientPropertyJTextField.variant":"search",
                   maximumSize: new Dimension(150,35),
                   preferredSize: new Dimension(150,35))
       }
       panel(id: 'centerPanel',
               constraints: CENTER,
               opaque: true,
               background: new Color(238, 238, 238)) {
           borderLayout()
           container (new SplitPaneWithThinDivider(),
                      id:'mainSplitPane',
                      constraints: CENTER,
                      dividerLocation: 150
                      ) {
               scrollPane(id:'treeScroller', border:null) {
                   tree(id:'explorerTree',
                           rootVisible: false)
               }
               scrollPane(border:null) {
                   textArea()
               }
           }
       }
   }
}

一种疯狂的，未经测试的猜测，但确实如此：

       widget( new SplitPaneWithThinDivider(),
               id:'mainSplitPane',
               constraints: CENTER,
               dividerLocation: 150,
               leftComponent: scrollPane(id:'treeScroller', border:null) {
                 tree(id:'explorerTree', rootVisible: false )
               },
               rightComponent: scrollPane(border:null) {
                 textArea()
               } )

完全工作？

答案 1 :(得分：0)

尝试使用Griffon 0.9.5-rc2的代码，但是使用了application（）而不是frame（）和splitPane（），因为我无法访问自定义的SplitPaneWithThinDivider组件并且它可以工作。我假设ExplorerFrameView属于辅助MVC组。您是否尝试过使用application（）而不是frame（）？

每个Views可以拥有尽可能多的application（）节点，因为此节点与frame（）具有几乎相同的行为，但它知道如何处理applet。

答案 2 :(得分：0)

感谢您的回复，Tim的版本完美无缺。我也尝试了以下内容：

splitPane (new SplitPaneWithThinDivider(),
           id:'mainSplitPane',
           constraints: CENTER,
           dividerLocation: 150,
           "clientPropertyQuaqua.Tree.style": "sideBar",
           border: null) {

   scrollPane(id:'treeScroller', border:null) {
       tree(id:'explorerTree',
            rootVisible: false)
   },           
   scrollPane(border:null) {
       textArea()
   }           
}

但是这样，splitpane的左侧组件始终是默认的“左键”（当我使用new JSplitPane()而不是new SplitPaneWithThinDivider()时，情况也是如此）。

当我将其更改为

时 
splitPane (new SplitPaneWithThinDivider(),
           id:'mainSplitPane',
           constraints: CENTER,
           dividerLocation: 150,
           "clientPropertyQuaqua.Tree.style": "sideBar",
           border: null) {

   scrollPane(id:'treeScroller', border:null) {
       tree(id:'explorerTree',
            rootVisible: false)
   },           
   scrollPane(border:null) {
       textArea()
   }           
}
bean(mainSplitPane, leftComponent: treeScroller)

它奏效了。
