The direct children of the ContextNode object.

Заметки

Примеры

This example is a method that recursively traverses a tree of ContextNode objects. It uses the SubNodes property and populates a System.Windows.Forms.TreeView by adding TreeNode objects. It then sets their Text properties to GetRecognizedString.

Private Sub WalkTree(ByVal parentContextNode As Microsoft.Ink.ContextNode, _
                     ByVal parentTreeNode As TreeNode)

    Dim cNode As ContextNode
    For Each cNode In parentContextNode.SubNodes
        Dim newTNode As New TreeNode(cNode.ToString())
        If TypeOf cNode Is Microsoft.Ink.InkWordNode Then
            newTNode.Text = newTNode.Text + _
                ": " + CType(cNode, InkWordNode).GetRecognizedString()
        ElseIf TypeOf cNode Is Microsoft.Ink.InkDrawingNode Then
            Dim shapeName As String = CType(cNode, InkDrawingNode).GetShapeName()
            If shapeName <> "" Then
                newTNode.Text = newTNode.Text + ": " + shapeName
            End If
        End If
        WalkTree(cNode, newTNode)
        parentTreeNode.Nodes.Add(newTNode)

        ' Add the context node as a tag of the tree node
        newTNode.Tag = cNode
    Next cNode

End Sub 'WalkTree

        private void WalkTree(ContextNode parentContextNode, TreeNode parentTreeNode)
        {
            foreach (ContextNode cNode in parentContextNode.SubNodes)
            {
                TreeNode newTNode = new TreeNode(cNode.ToString());
                if (cNode is Microsoft.Ink.InkWordNode)
                {
                    newTNode.Text +=
                        ": " + ((InkWordNode)cNode).GetRecognizedString();
                }
                else if (cNode is Microsoft.Ink.InkDrawingNode)
                {
                    String shapeName = ((InkDrawingNode)cNode).GetShapeName();
                    if (shapeName != "")
                        newTNode.Text += ": " + shapeName;
                }
                WalkTree(cNode, newTNode);
                parentTreeNode.Nodes.Add(newTNode);

                // Add the context node as a tag of the tree node
                newTNode.Tag = cNode;
            }
        }
