是否可以在Eclipse中创建自定义变量查看器?假设我希望分解位域或将位图看作图像。有可能吗?
你能举出一些最简单的例子吗?
更新
我的plugin.xml
如下:
<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.0"?>
<plugin>
<extension
point="org.eclipse.debug.ui.detailPaneFactories">
<detailFactories
class="tests.debug.details.DetailPaneFactory"
id="tests.debug.details.detailFactories">
</detailFactories>
</extension>
</plugin>
我的DetailPaneFactory.java
如下:

}
@Override

}
我的SimpleDetailPane.java
与示例相同。
它显然有效。
答案 0 :(得分:3)
您可以使用窗口/显示视图/表达式并添加可以进行一些计算并显示文本输出的表达式。但除了文本输出之外,您还必须通过Eclipse平台扩展点贡献自己的模型演示文稿。请参阅Eclipse自己的JDT中的Detail Pane Factories Extension和org.eclipse.temp.JavaTableDetailPaneFactory
类的来源。
作为一种快速解决方法,您还可以编写一个静态实用程序方法,该方法将打开一个新窗口,其中您的图像从位域转换,并使用Ctrl-U快捷方式从显示视图调用该方法。
