RCP去掉多余菜单项

   在Eclipse RCP开发中，如果你的dependencies中包含了org.eclipse.ui.ide，在创建菜单栏是你会发现出现了多余的菜单项，例如"Convert Line Delimiters to"和"Last Edit Location"这两个菜单项。如何去掉这些多余的菜单项呢？

可以在你的ApplicationActionBarAdvisor类中添加如下代码(可以在makeActions方法中调用以下代码)：

    /*
     * 去掉因为导入依赖包(org.eclipse.ui.ide)而产生的多余的菜单项，一般
     * 情况下包括三个
     */
    @SuppressWarnings("restriction")
    public void removeDuplicateAction()
    {
    	ActionSetRegistry reg = WorkbenchPlugin.getDefault().getActionSetRegistry();
    	IActionSetDescriptor[] actionSets = reg.getActionSets();
    	// removing annoying gotoLastPosition Message.
    	String actionSetId = "org.eclipse.ui.edit.text.actionSet.navigation"; //$NON-NLS-1$
    	for (int i = 0; i <actionSets.length; i++)
    	{
    	    if (!actionSets[i].getId().equals(actionSetId))
    	        continue;
    	        IExtension ext = actionSets[i].getConfigurationElement()
    	            .getDeclaringExtension();
    	        reg.removeExtension(ext, new Object[] { actionSets[i] });
    	}
    	// Removing convert line delimiters menu.
    	actionSetId = "org.eclipse.ui.edit.text.actionSet.convertLineDelimitersTo"; //$NON-NLS-1$
    	for (int i = 0; i <actionSets.length; i++)
    	{
    	    if (!actionSets[i].getId().equals(actionSetId))
    	        continue;
    	    IExtension ext = actionSets[i].getConfigurationElement()
    	            .getDeclaringExtension();
    	   reg.removeExtension(ext, new Object[] { actionSets[i] });
    	}
    	actionSetId = "org.eclipse.ui.actionSet.openFiles";
    	for (int i = 0; i <actionSets.length; i++)
    	{
    	    if (!actionSets[i].getId().equals(actionSetId))
    	        continue;
    	    IExtension ext = actionSets[i].getConfigurationElement()
    	            .getDeclaringExtension();
    	   reg.removeExtension(ext, new Object[] { actionSets[i] });
    	}
    }

谢谢 。。代码写得不够简洁
