Namespace: Microsoft.Ink
Assembly: Microsoft.Ink.Analysis (in microsoft.ink.analysis.dll)

Syntax

'Declaration
Public ReadOnly Property SubNodes As ContextNodeCollection
'Usage
Dim instance As ContextNode
Dim value As ContextNodeCollection

value = instance.SubNodes

public ContextNodeCollection SubNodes { get; }

public:
property ContextNodeCollection^ SubNodes {
    ContextNodeCollection^ get ();
}

/** @property */
public ContextNodeCollection get_SubNodes ()

public function get SubNodes () : ContextNodeCollection

Not applicable.

Property Value

The direct children of the ContextNode object.

Remarks

This returns only the direct children, not all of the descendants.

Example

This example is a method that recursively traverses a tree of ContextNode objects. It uses the SubNodes property and populates a System.Windows.Forms.TreeViewSystem.Windows.Forms.TreeView by adding TreeNodeTreeNode 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(
    Microsoft.Ink.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;
    }
}
