HTMLWindow3 类型公开以下成员。

属性

	名称	说明
	CurrentPane	获取或设置当前 HTML 编辑器的窗口类型。
	CurrentView	获取或设置 HTML 编辑器窗口在“源”视图、“设计器”视图还是“拆分”视图中。

页首

方法

	名称	说明
	WaitForBackgroundProcessingComplete	暂停程序执行，直至后台处理完成。

页首

备注

当文档是 HTML 文档时，Window 对象的 Object 属性返回 HTMLWindow3。 当 CurrentTab 属性设置为 vsHTMLTabsSource 时，Window.Selection 和 Document.Selection 返回一个 TextSelection 对象。

随着 Visual Studio 2008 HTML 编辑器中“拆分”视图的引入，增加了 HTMLWindow3、vsHTMLPanes 和 vsHTMLViews。 “拆分”视图将 HTML 编辑器窗口的选项卡和视图元素分隔开来。 切换视图（到“设计”或“源”视图）并不一定意味着切换选项卡（“设计”/“拆分”/“源”）。 例如，当您单击“拆分”选项卡时，在“设计”和“源”之间切换视图不会更改选项卡，而只会在“拆分”视图中激活或取消激活“设计”和“源”部分。

Visual Studio 2008 HTMLWindow 对象现在还实现 HTMLWindow3 接口，该接口返回当前视图（“设计”或“源”）和当前窗格（“设计”、“源”或“拆分”选项卡）。

HTMLWindow3 规则

HTMLWindow3 的行为是：
