Determines whether a point is inside a shape.

Namespace: Microsoft.VisualStudio.Modeling.Diagrams
Assembly: Microsoft.VisualStudio.Modeling.Sdk.Diagrams (in Microsoft.VisualStudio.Modeling.Sdk.Diagrams.dll)

Syntax

'Declaration
Public Function DoHitTest ( _
    geometryHost As IGeometryHost, _
    hitPoint As PointD, _
    hitTestInfo As DiagramHitTestInfo _
) As Boolean

'Usage
Dim instance As ShapeGeometry 
Dim geometryHost As IGeometryHost 
Dim hitPoint As PointD 
Dim hitTestInfo As DiagramHitTestInfo 
Dim returnValue As Boolean 

returnValue = instance.DoHitTest(geometryHost, _
    hitPoint, hitTestInfo)

public bool DoHitTest(
    IGeometryHost geometryHost,
    PointD hitPoint,
    DiagramHitTestInfo hitTestInfo
)

public:
bool DoHitTest(
    IGeometryHost^ geometryHost, 
    PointD hitPoint, 
    DiagramHitTestInfo^ hitTestInfo
)

public function DoHitTest(
    geometryHost : IGeometryHost, 
    hitPoint : PointD, 
    hitTestInfo : DiagramHitTestInfo
) : boolean

Parameters

geometryHost
Type: Microsoft.VisualStudio.Modeling.Diagrams.IGeometryHost

The shape or link.

hitPoint
Type: Microsoft.VisualStudio.Modeling.Diagrams.PointD

The point to test, relative to the boundary of the shape.

hitTestInfo
Type: Microsoft.VisualStudio.Modeling.Diagrams.DiagramHitTestInfo

The object that will receive the results of the hit test.

Return Value

Type: System.Boolean
true if the point is inside the shape; otherwise, false.

Remarks

The geometry boundary includes the thickness of the outline pen that lies outside of the graphics path used to draw the geometry.
