Eclipseが提供するOverride/Implementに似たウィジェットを実装するには？

Question

私はいくつかのアクションを実行し、Eclipseが提供するOverride Implemetウィンドウに同様のウィンドウを表示したいと思います。

私はthis postを見つけましたが、まだそれで苦労しています。

私はアクションを作成しました：

<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> 

私はちょうどOverrideMethodsAction EclipseのクラスをコピーしてMyViewActionにそれを改名しました。私は私の新しいアクションをクリックすると は、私は例外を取得：

!ENTRY org.eclipse.libra.facet 4 0 2012-01-09 14:50:54.635 
    !MESSAGE startup class must implement org.eclipse.ui.IStartup

私は他に何をすべきか、または他にどこ見て見当がつかない。

おかげ

EDIT：

私は、引数なしのコンストラクタを追加することができませんでした。私はそれをどうやって行うのか分かりません。

私はもう一度クラスを開始しました。クラスGenerateToStringAction、GenerateMethodAbstractAction、およびSelectionDispatchActionをプロジェクトにコピーし、GenerateToStringActionAG、GenerateMethodAbstractActionAG、およびSelectionDispatchActionAGという名前に変更しました。

私は私が私のアクションをクリックしたときにGenerateToString（）ウィンドウを表示するために期待していたが、代わりに私が得た：

私は、私は非常に間違った方法でつもりだと思います。

Answer 1

クラスtest.plugin.popup.actions.MyViewActionには、引数のないコンストラクタが必要です。

私たちがいる間に、this answerを見てみるといいでしょう。
