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] });    }    }
