Question

我正在使用Eclipse SWT-Application在项目中工作。在所有视图的选项卡上都有默认操作，例如“Detached”-Action，它接受选项卡并为其创建一个分离窗口。在我们的例子中，这导致以下例外：

我知道ENABLE_DETACHED_VIEWS中有一个名为IWorkbenchPreferenceConstants的常量，其默认值为true。

我现在尝试一般禁用“Detached”-Action（也提示如何在一个视图中禁用它）。有没有办法可以覆盖所述常量的默认值，或者从我的选项卡上的右键菜单中删除“Detached”-action的任何其他方式？

感谢您的帮助

编辑：我们正在使用SWT 3.6

好的，我自己发现了。据我所知，你必须延长WorkbenchAdvisor。在此子类中，您必须覆盖createWorkbenchWindowAdvisor，您可以在其中覆盖IWorkbenchPreferenceConstants，如下所示：

@Override
    public WorkbenchWindowAdvisor createWorkbenchWindowAdvisor(IWorkbenchWindowConfigurer configurer) {
        PlatformUI.getPreferenceStore().setValue(IWorkbenchPreferenceConstants.ENABLE_DETACHED_VIEWS, false);
        return new ApplicationWorkbenchWindowAdvisor(configurer);
    }

这将阻止应用程序分离任何视图，并删除右键单击操作“已分离”。

请注意（根据我的发现）此解决方案仅适用于版本3.X

在SWT中禁用“Detached” - 动作 - “Wrong parent” - 异常
