Parameters
- point
Type: Microsoft.VisualStudio.Modeling.Diagrams.PointD
The top-left point in the diagram.
- hitTestInfo
Type: Microsoft.VisualStudio.Modeling.Diagrams.DiagramHitTestInfo
The object that receives the results of the hit test.
- includeTolerance
Type: System.Boolean
true to include tolerance around the shape when the hit test determines whether the shape has been hit; otherwise, false. Tolerance increases the hit diameter around the shape.
Return Value
Type: System.Boolean
true if the shape was hit; otherwise, false.
