Syntax
'Declaration
Public Overrides Function DoHitTest ( _
point As PointD, _
hitTestInfo As DiagramHitTestInfo, _
includeTolerance As Boolean _
) As Boolean
'Usage
Dim instance As Diagram
Dim point As PointD
Dim hitTestInfo As DiagramHitTestInfo
Dim includeTolerance As Boolean
Dim returnValue As Boolean
returnValue = instance.DoHitTest(point, _
hitTestInfo, includeTolerance)
public override bool DoHitTest(
PointD point,
DiagramHitTestInfo hitTestInfo,
bool includeTolerance
)
public:
virtual bool DoHitTest(
PointD point,
DiagramHitTestInfo^ hitTestInfo,
bool includeTolerance
) override
public override function DoHitTest(
point : PointD,
hitTestInfo : DiagramHitTestInfo,
includeTolerance : boolean
) : boolean
Parameters
point
Type: Microsoft.VisualStudio.Modeling.Diagrams.PointDThe top-left point in the diagram.
hitTestInfo
Type: Microsoft.VisualStudio.Modeling.Diagrams.DiagramHitTestInfoThe object that receives the results of the hit test.
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.
