java更改开放式帮助搜索首选项

Question

我找到了一种通过以下代码更改打开帮助搜索首选项的方法：

IEclipsePreferences pref = InstanceScope.INSTANCE.getNode(HelpBasePlugin.PLUGIN_ID);

pref.put(IHelpBaseConstants.P_KEY_SEARCH_FROM_BROWSER, "whatever");
//apparently the second String is unimportant as it will always change "Open Help Search" to "In the dynamic help view"

不管怎样，现在我想在浏览器

然而，通过IHelpBaseConstants查看，我发现只有打开帮助查看文档的值和键

是否还有其他类、API或我可能错过的东西可以改变帮助首选项
