ContextNodeBase.IsConfirmed 方法

获取一个值，该值指示 ContextNodeBase 对象是否已确认。InkAnalyzerBase 不能更改已确认对象的节点类型和关联的笔画。

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

语法

声明
Public Function IsConfirmed ( _
    type As ConfirmationType _
) As Boolean
用法
Dim instance As ContextNodeBase
Dim type As ConfirmationType
Dim returnValue As Boolean

returnValue = instance.IsConfirmed(type)

public bool IsConfirmed(
    ConfirmationType type
)

public:
bool IsConfirmed(
    ConfirmationType type
)

public boolean IsConfirmed(
    ConfirmationType type
)

public function IsConfirmed(
    type : ConfirmationType
) : boolean

参数

• type
  类型：System.Windows.Ink.AnalysisCore.ConfirmationType
  ConfirmationType。

返回值

类型：System.Boolean
如果节点类型已确认，则为 true；否则为 false。

备注

此值由 Confirm 方法设置。

示例

下面的示例是 Panel (theNotesPanel) 上的 MouseUp 事件的事件处理程序，该处理程序正在通过名为 theInkCollector 的 InkCollector 收集墨迹。应用程序有一个名为 confirmMode 的 Boolean 值，该值由名为 confirmMenuItem 的 MenuItem 进行设置。在“确认”模式下，用户单击一个词进行确认（或者，如果该节点已确认，则关闭确认）。该示例将鼠标释放事件转换为墨迹坐标。它使用 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。
