如何以编程方式在eclipse插件中添加右键菜单

Question

I have an eclipse plugin with a View part. In this View part I have a table and I want to add a submenu when a user right clicks on a row in that table. How can I do this programatically?

I have defined the command and menuContribution in my plugin.xml:

<extension
     point="org.eclipse.ui.menus">
   <menuContribution
        allPopups="true"
        class="com.sintec.eclipseplugins.clippy.menu.DeleteMenuContribution"
        locationURI="menu:delete?after=additions">
   </menuContribution>
</extension>

I have also created the contribution class extending ExtensionContributionFactory:

public class DeleteMenuContribution extends ExtensionContributionFactory {

@Override
public void createContributionItems(IServiceLocator serviceLocator, IContributionRoot additions) {
    // build a couple of command-based contribution parameters
    CommandContributionItemParameter pAA = new CommandContributionItemParameter(
        serviceLocator,
        "DeleteCommand",
        "com.sintec.eclipseplugins.clippy.delete",
        SWT.PUSH);
    pAA.label = "Delete Command";

    // create actual contribution items and add them to the given additions reference
    CommandContributionItem itemAA = new CommandContributionItem(pAA);
    itemAA.setVisible(true);
    additions.addContributionItem(itemAA, null);

}

}

Aaaand last but not least I have this code my ViewPart where I want to add the menu to the table:

IMenuManager mgr = new MenuManager().findMenuUsingPath("menu:delete?after=additions");
MenuManager mgr2 = new MenuManager();
mgr2.add(mgr);
tableViewer.getTable().setMenu(mgr2.createContextMenu(tableViewer.getTable()));

The problem is that the menu can not be found. I'm pretty sure I'm missing something ... Is the menu URI correct?

我有点at ...但是为什么不给菜单分配一个id并在MenuManager中使用find（id）方法呢？
