Parameters
- view
Type: Microsoft.VisualStudio.Modeling.Diagrams.DiagramClientView
The client view for the diagram. If the diagram does not have a client view, nulla null reference (Nothing in Visual Basic).
- point
Type: Microsoft.VisualStudio.Modeling.Diagrams.PointD
The top-left point in the diagram.
- shapesHit
Type: System.Collections.Generic.List<ShapeElement>
The object to receive the list of hit shapes.
- 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.
Remarks
A hit test verifies whether a point is over a shape on the diagram.
