JXTreeTable:如何使用ComponentProvider为一列设置渲染器

时间:2012-02-08 09:39:11

标签: java swing swingx jtreetable

我正在使用JXTreeTable来显示一些数据,我想使用提供的SwingX机制来更改某些列的渲染器。

我以前使用了TableCellRenderer的JXTable和自定义实现,但这不再起作用了(我看到字符串,我应该有进度条,按钮,......)。

因此,我努力实现我的目标:

examsTable.getColumn(6).setCellRenderer(new DefaultTableRenderer(new ButtonProvider()));

但ComponentProvider的重写方法createRenderer被调用一次(即使我的JXTreeTable中有多行)并且没有显示任何按钮(该方法只包含return new JButton();)。

谢谢!

我尽了最大努力但不知何故表格没有显示。我想我忘了一些东西(我是Java新手,但我认为这不是一个严重的问题,而且可能与我的主要问题无关。

编辑&gt; 我实际上已经发现它有效。但不是我想要的方式。我想看一个真正的按钮(现在它看起来与线的其余部分略有不同),知道它的路径(父对象和列索引)并查看点击或悬停在其上的效果(按钮应该看起来按下,...)。

我如何实现这一目标?

答案 0 :(得分:4)

使用该按钮,它似乎只出现在某些LAF中: - )

从技术上讲,原因是

  • 荧光笔设置按钮的背景
  • 默认视觉效果(由提供者使用)将边框设置为cellContext返回的默认值

组合时,按钮看起来不像Metal的按钮(在Windows中它没有变化f.i.)

没有令人满意的解决方案,选项

  • 不使用条纹
  • 让按钮具有不触摸我的背景属性,扩展ColorHighlighter以尊重它并使用该自定义荧光笔进行条带化(测试包中有一个示例)
