LinkShapeGeometry.DoHitTest Method (IGeometryHost, PointD, DiagramHitTestInfo, Boolean)

Returns a value indicating whether the given point is within the boundary of the geometry. The hit test results are also returned.

Namespace:  Microsoft.VisualStudio.Modeling.Diagrams

Parameters

• geometryHost
  Type: Microsoft.VisualStudio.Modeling.Diagrams.IGeometryHost
  The instance data for the geometry.

• hitPoint
  Type: Microsoft.VisualStudio.Modeling.Diagrams.PointD
  The point to test. The point is in world units and is relative to the top-left of the IGeometryHost's parent.

• hitTestInfo
  Type: Microsoft.VisualStudio.Modeling.Diagrams.DiagramHitTestInfo
  The object which will be updated with the hit test results. This argument may be null in which case it is ignored.

• includeTolerance
  Type: System.Boolean
  true if the tolerance around the geometry should be included when determining if the geometry was hit.

Return Value

Type: System.Boolean

Remarks

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