Exemples

Cet exemple est une méthode qui parcourt de manière récursive une arborescence d'objets ContextNode. Il utilise la propriété SubNodes et remplit un [System.Windows.Controls.TreeView] en ajoutant des objets TreeViewItem. Il affecte alors la méthode GetRecognizedString à leurs propriétés Header.

Private Shared Sub WalkTree(ByVal parentContextNode As ContextNode, ByVal parentTreeNode As TreeViewItem) 

    parentTreeNode.IsExpanded = True

    For Each theContextSubnode As ContextNode In parentContextNode.SubNodes
        Dim newTreeNode As New TreeViewItem()
        newTreeNode.Header = theContextSubnode.ToString()

        If TypeOf theContextSubnode Is InkWordNode Then
            newTreeNode.Header += ": " + CType(theContextSubnode, InkWordNode).GetRecognizedString()
        ElseIf TypeOf theContextSubnode Is InkDrawingNode Then
            newTreeNode.Header += ": " + CType(theContextSubnode, InkDrawingNode).GetShapeName()
        End If

        ' If the context node is confirmed, add a note to the
        ' tree view item.
        If (theContextSubnode.IsConfirmed(ConfirmationType.NodeTypeAndProperties)) Then

            newTreeNode.Header += " Confirmed."
        End If


        ' Add the context node as a tag of the tree view item and
        ' add the new tree view item to the parent node.
        newTreeNode.Tag = theContextSubnode
        parentTreeNode.Items.Add(newTreeNode)

        WalkTree(theContextSubnode, newTreeNode)
    Next theContextSubnode

End Sub 'WalkTree

private static void WalkTree(ContextNode parentContextNode, TreeViewItem parentTreeNode)
{
    // Expand the current TreeViewItem.
    parentTreeNode.IsExpanded = true;

    foreach (ContextNode theContextSubnode
        in parentContextNode.SubNodes)
    {
        TreeViewItem newTreeNode = new TreeViewItem();
        newTreeNode.Header = theContextSubnode.ToString();

        if (theContextSubnode is InkWordNode)
        {
            newTreeNode.Header += ": " +
                ((InkWordNode)theContextSubnode).GetRecognizedString();
        }
        else if (theContextSubnode is InkDrawingNode)
        {
            newTreeNode.Header += ": " +
                ((InkDrawingNode)theContextSubnode).GetShapeName();
        }

        // If the context node is confirmed, add a note to the
        // tree view item.
        if (theContextSubnode.IsConfirmed(ConfirmationType.NodeTypeAndProperties))
        {
            newTreeNode.Header += " Confirmed.";
        }

        // Add the context node as a tag of the tree view item and
        // add the new tree view item to the parent node.
        newTreeNode.Tag = theContextSubnode;
        parentTreeNode.Items.Add(newTreeNode);

        WalkTree(theContextSubnode, newTreeNode);
    }
