从Eclipse中的CNF（Common Navigator Framework）中删除popUpMenus

Question

通过配置plugin.xml文件，我已经部分成功地从Commons Navigator Framework中删除了几乎所有的popUp菜单。 有两个拒绝的菜单：

• group.edit和
• group.reorganize。

我的plugin.xml配置看起来像这样：

<extension
          point="org.eclipse.ui.navigator.viewer">
       <viewer
             viewerId="org.eclipse.ui.example.navigator.view">
             <popupMenu allowsPlatformContributions="false">
                <insertionPoint
                    name="group.edit" />

                <insertionPoint
                    name="group.reorganize" />
             </popupMenu>
       </viewer>
       <viewerContentBinding
             viewerId="org.eclipse.ui.thermo.navigator.view">
          <includes>
             <contentExtension
                   pattern="org.eclipse.ui.navigator.resourceContent"/>
          </includes>
       </viewerContentBinding> 
</extension>

将allowsPlatformContribution设置为false DOES停止将贡献添加到上下文菜单中，除了group.edit和group.reorganize ...这对我来说开始看起来像个错误。

显而易见的解决方案是从我的<popUpMenu>中删除插入点，但没有它们，应用程序会抛出异常：

Throwable: java.lang.IllegalArgumentException: Group not found: group.edit

at org.eclipse.jface.action.MenuManager.access$1(MenuManager.java:459)
at org.eclipse.jface.action.MenuManager$2.menuShown(MenuManager.java:485)

它会为重组组抛出相同的异常。

我成功删除了“group.edit”操作（复制/粘贴），并且我已经这样做了，使用Common Navigator扩展点：

   <extension
         point="org.eclipse.ui.navigator.viewer">
      <viewerActionBinding
            viewerId="org.eclipse.ui.navigator.ProjectExplorer">
         <includes>
            <actionExtension
                  pattern="my.app.client.actions.MyAppEditActionExtension">
            </actionExtension>
         </includes>
      </viewerActionBinding>    
   </extension>
   <extension
         point="org.eclipse.ui.navigator.navigatorContent">
      <actionProvider
            class="my.app.client.workshop.MyPasteActionProvider"
            id="my.app.client.actions.MyAppEditActionExtension"
            overrides="org.eclipse.ui.navigator.resources.actions.EditActions"
            priority="highest">
         <enablement>
         <!-- A hack to allways be enabled -->
         <not>
            <systemTest
                  property="MyApp"
                  value="WONT-EVER-BE-SET">
            </systemTest>
         </not>
         </enablement>
     </actionProvider>
   </extension>

并且，在我的插件依赖项中添加了“org.eclipse.ui.navigator.resources”，我实现了“MyPasteActionProvider”，如下所示：

import org.eclipse.jface.action.IContributionItem;
import org.eclipse.jface.action.IMenuManager;
import org.eclipse.ui.internal.navigator.resources.actions.EditActionProvider;

/**
 * Create the Edit actions (Cut/Copy/Paste) 
 * and register then globally in the workbench using EditActionProvider.
 * <p/>
 * Then, removes the Copy/Paste contributions in the pop-up menu.
 */
public class MyPasteActionProvider extends EditActionProvider {
   public void fillContextMenu(IMenuManager menu) { super.fillContextMenu(menu);
   // remove Copy/Paste contributions
   IContributionItem copyItemRemoved = menu.remove("org.eclipse.ui.CopyAction");
   IContributionItem pasteItemRemoved = menu.remove("org.eclipse.ui.PasteAction");
   }
}

嗯，这是一个“气馁的访问”，但我让自己气馁;-) JM.D

通常，您应该将Command Framework与最新版本的Eclipse（3.3或更高版本）一起使用，这取代了在Common Navigator中提供弹出菜单的机制。

这个thread suggests删除导致菜单项首先出现的东西：

它们可能处于动作集中，因此如果您能够识别导致攻击性贡献的动作集，则可以在WorkbenchAdvisor中执行以下操作：

    ActionSetRegistry reg = WorkbenchPlugin.getDefault()
            .getActionSetRegistry();


    IActionSetDescriptor[] actionSets = reg.getActionSets();
    String[] removeActionSets = new String[] {
        "org.eclipse.ui.cheatsheets.actionSet",
        "org.eclipse.ui.edit.text.actionSet.annotationNavigation",
       "org.eclipse.ui.edit.text.actionSet.convertLineDelimitersTo",
          "org.eclipse.ui.WorkingSetActionSet",
        "org.eclipse.update.ui.softwareUpdates", };


    for (int i = 0; i < actionSets.length; i++)
    {
        boolean found = false;
        for (int j = 0; j < removeActionSets.length; j++)
        {
            if (removeActionSets[j].equals(actionSets[i].getId()))
                found = true;
        }


        if (!found)
            continue;
        IExtension ext = actionSets[i].getConfigurationElement()
                .getDeclaringExtension();
        reg.removeExtension(ext, new Object[] { actionSets[i] });
    }

我发现的最接近的错误是145233: Make more obvious way to specify input (for RCP apps)，有一个similar hack。 Bug 143430 (CommonNavigator requires initialInput to be Adaptable)是一个更普遍的，并且表明CNF已经使用eclipse3.5（Galileo）进行了改进。 那么你也有这个问题与3.5和自定义CNF类？

正如文章“Eclipse CNF: Navigator Content Extensions”中所提到的，CNF已经与eclipse3.5一起发展，本文似乎有一些树具有真正的自定义上下文菜单条目。
