RCP去掉多余菜单

 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)：

Java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 
*/

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] });  
    }  
}
