ConfirmationType 枚举

定义用于指定可以在 ContextNodeBase 对象上发生的类型确认的值。

此枚举有一个 FlagsAttribute 属性，通过该属性可使其成员值按位组合。

命名空间：  System.Windows.Ink.AnalysisCore
程序集：  IACore（在 IACore.dll 中）

语法

声明
<FlagsAttribute> _
Public Enumeration ConfirmationType
用法
Dim instance As ConfirmationType

[FlagsAttribute]
public enum ConfirmationType

[FlagsAttribute]
public enum class ConfirmationType

/** @attribute FlagsAttribute */
public enum ConfirmationType

public enum ConfirmationType

成员

	成员名称	说明
	None	指定不应用任何确认。InkAnalyzer 可以根据需要自由更改上下文节点或其任何后代。
	NodeTypeAndProperties	指定 InkAnalyzer 不能更改指定上下文节点的类型或任何属性。
	TopBoundary	指定 InkAnalyzerBase 不执行导致 TopBoundary 移出当前上边界的操作（包括添加墨迹或与其他 ContextNodeBase 合并）。例如：

备注

只能对 InkWord 和 InkDrawing 类型的 ContextNodeBase 对象使用 NodeTypeAndProperties。否则会引发 InvalidOperationException。

示例

下面的示例是 Panel（名为 theNotesPanel）上的 MouseUp 事件的事件处理程序，该处理程序通过名为 theInkCollector 的 InkCollector 收集墨迹。应用程序有一个 Boolean 值 confirmMode，该值由名为 confirmMenuItem 的 MenuItem 设置。在“确认”模式中，用户单击单词以确认它（或者，如果已经确认节点，则关闭确认）。该示例将 MouseUp 事件转换为墨迹坐标，使用 HitTest 和 FindNodesOfType 查找相应的节点。在找到节点之后，调用 Confirm 以切换确认。最后，应用程序脱离“确认”模式。
