Примеры

The following example uses the IsConfirmed() method to switch the confirmation state of the ContextNode. The example is an event handler for the Control.MouseUp event on a Panel, theNotesPanel, which is collecting ink through an InkCollector, theInkCollector. The application has a Boolean, confirmMode, which is set by a MenuItem, confirmMenuItem. When in "confirm" mode, the user clicks a word to confirm it (or to turn off confirmation if the node is already confirmed). The example converts the mouse up event into ink coordinates. It uses HitTest and FindNodesOfType to find the appropriate nodes. After the nodes are found, Confirm is called to toggle the confirmation. Finally, the application is taken out of "confirm" mode.

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

private void theNotesPanel_MouseUp(object sender, MouseEventArgs e)
{
    if (this.confirmMode)
    {
        // Translate coordinates into ink dimensions
        Point hitPoint = new Point(e.X, e.Y);
        Graphics panelGraphics = this.theNotesPanel.CreateGraphics();
        this.theInkCollector.Renderer.PixelToInkSpace(panelGraphics, ref hitPoint);
        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;
    }
