如何实现与Eclipse提供的Override/Implement类似的小部件？

我想执行一些操作，并显示一个类似的窗口，以供Eclipse提供的Override Implemet窗口使用。我发现this post，但我仍然在努力。如何实现与Eclipse提供的Override/Implement类似的小部件？

我创建的操作：

<objectContribution 
      id="Test.objectContribution1" 
      objectClass="org.eclipse.core.resources.IProject"> 

      <action 
       label="MyView" 
       retarget="true" 
       menubarPath="addition" 
       class="test.plugin.popup.actions.MyViewAction" 
       id="test.plugin.popup.actions.MyViewAction" 
       > 
     </action>

我刚才复制的OverrideMethodsAction Eclipse的类并将其重命名为MyViewAction。当我点击我的新动作，我得到异常：

我不知道还能做什么或别的地方看看。

感谢

编辑：

我不能添加一个无参数的构造函数。我不知道该怎么做。

我重新开始，我将类GenerateToStringAction，GenerateMethodAbstractAction和SelectionDispatchAction复制到我的项目中，并将它们重命名为GenerateToStringActionAG，GenerateMethodAbstractActionAG和SelectionDispatchActionAG。

我期待看到GenerateToString（）窗口当我点击我的动作，而是我：

我想我在一个非常错误的方式去。

我不清楚你试图达到什么目的。您想要显示一个与“覆盖/实施方法”对话框类似的对话框。它必须是相同的对话框还是只是类似的东西？究竟有多相似，应该有什么不同？复制类几乎肯定不是一个好主意。 – 2012-01-10 21:09:35

您的类test.plugin.popup.actions.MyViewAction需要一个无参数构造函数。

虽然我们在这，但你可能想看看this answer。
