Syntax
'Declaration
Public Overridable Function DoHitTest ( _

'Usage
Dim instance As Diagram
Dim view As DiagramClientView
Dim point As PointD
Dim shapesHit As List(Of ShapeElement)
Dim includeTolerance As Boolean
Dim returnValue As Boolean
returnValue = instance.DoHitTest(view, _
point, shapesHit, includeTolerance)
public virtual bool DoHitTest(

PointD point,
List<ShapeElement> shapesHit,
bool includeTolerance
)
public:
virtual bool DoHitTest(
DiagramClientView^ view,
PointD point,
List<ShapeElement^>^ shapesHit,
bool includeTolerance
)
public function DoHitTest(
view : DiagramClientView,
point : PointD,
shapesHit : List<ShapeElement>,
includeTolerance : boolean
) : boolean
Parameters
view
Type: Microsoft.VisualStudio.Modeling.Diagrams.DiagramClientViewThe 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.PointDThe 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.Booleantrue 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.
