ContextNode.IsConfirmed 方法

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

命名空间：  Microsoft.Ink
程序集：  Microsoft.Ink.Analysis（在 Microsoft.Ink.Analysis.dll 中）

语法

声明
Public Function IsConfirmed ( _
    type As ConfirmationType _
) As Boolean
用法
Dim instance As ContextNode
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：Microsoft.Ink.ConfirmationType
  要检查的确认类型。

返回值

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

示例

下面的示例使用 IsConfirmed() 方法切换 ContextNode 的确认状态。该示例是 Panel (theNotesPanel) 上的 Control.MouseUp 事件的事件处理程序，它在通过 InkCollector (theInkCollector) 收集墨迹。应用程序有一个 Boolean (confirmMode)，它由 MenuItem (confirmMenuItem) 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。

Private Sub theNotesPanel_MouseUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles theNotesPanel.MouseUp
    If Me.confirmMode = True Then
        ' Translate coordinates into ink dimensions
        Dim hitPoint As New Point(e.X, e.Y)
        Dim panelGraphics As Graphics = Me.theNotesPanel.CreateGraphics()
        Me.theInkCollector.Renderer.PixelToInkSpace(panelGraphics, hitPoint)
        panelGraphics.Dispose()

        ' Find the strokes that the user selected
        Dim selectedStrokes As Strokes = Me.theInkCollector.Ink.HitTest(hitPoint, 10)

        ' Find the ink word nodes that correspond to those strokes
        Dim selectedNodes As ContextNodeCollection = _
            Me.theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.InkWord, _
            selectedStrokes)

        ' Toggle the confirmation type on these nodes
        Dim selectedNode As ContextNode
        For Each selectedNode In selectedNodes
            If selectedNode.IsConfirmed(ConfirmationType.NodeTypeAndProperties) = True Then
                selectedNode.Confirm(Microsoft.Ink.ConfirmationType.None)
            Else
                selectedNode.Confirm(Microsoft.Ink.ConfirmationType.NodeTypeAndProperties)
            End If
        Next selectedNode

        ' No longer in "confirm" mode
        Me.confirmMode = False
        Me.ConfirmMenuItem.Checked = False
        Me.theInkCollector.Enabled = True
    End If

End Sub

        panelGraphics.Dispose();

        // Find the strokes that the user selected
        Strokes selectedStrokes = this.theInkCollector.Ink.HitTest(hitPoint, 10);

        // Find the ink word nodes that correspond to those strokes
        ContextNodeCollection selectedNodes =
            this.theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.InkWord,
            selectedStrokes);

        // Toggle the confirmation type on these nodes
        foreach (ContextNode selectedNode in selectedNodes)
        {
            if (selectedNode.IsConfirmed(ConfirmationType.NodeTypeAndProperties))
            {
                selectedNode.Confirm(Microsoft.Ink.ConfirmationType.None);
            }
            else
            {
                selectedNode.Confirm(Microsoft.Ink.ConfirmationType.NodeTypeAndProperties);
            }
        }

        // No longer in "confirm" mode
        this.confirmMode = false;
        this.confirmMenuItem.Checked = false;
        this.theInkCollector.Enabled = true;
