Property Value

The position and size of the ContextNode object.

Remarks

The location for a given ContextNode is determined by the union of the location of all strokes. If the ContextNode is a leaf node, strokes associated with that node are used. If the ContextNode is not a leaf node, all descendant leaf ContextNode objects are used to determine the location of the ContextNode.

If the ContextNode is not an ink leaf node or does not have any descendant ink leaf nodes, the node is considered to be a non-ink node or an ancestor of one or more non-ink nodes. The location of this type of node is determined by the location value of the non-ink leaf nodes.

Example

This example draws a blue box around a ContextNode, cNode, whose strokes have been drawn on an InkCanvas, theInkCanvas.

Dim selectedNodeBounds As Rect = currentNode.Location.GetBounds()
Dim bounds As New Rectangle()

bounds.Width = selectedNodeBounds.Width
bounds.Height = selectedNodeBounds.Height

bounds.SetValue(InkCanvas.TopProperty, selectedNodeBounds.Top)
bounds.SetValue(InkCanvas.LeftProperty, selectedNodeBounds.Left)
bounds.Stroke = Brushes.Blue
Me.theInkCanvas.Children.Add(bounds)

Rect selectedNodeBounds = currentNode.Location.GetBounds();
Rectangle bounds = new Rectangle();

bounds.Width = selectedNodeBounds.Width;
bounds.Height = selectedNodeBounds.Height;

bounds.SetValue(InkCanvas.TopProperty, selectedNodeBounds.Top);
bounds.SetValue(InkCanvas.LeftProperty, selectedNodeBounds.Left);
bounds.Stroke = Brushes.Blue;
this.theInkCanvas.Children.Add(bounds);
