RCP去掉多余菜单(转)

EXT Eclipse UI IDE

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
*/
@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] });
    }
}

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

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