public abstract function DoHitTest(
geometryHost : IGeometryHost,
hitPoint : PointD,
hitTestInfo : DiagramHitTestInfo,
includeTolerance : boolean
) : boolean
Parameters
geometryHost
Type: Microsoft.VisualStudio.Modeling.Diagrams.IGeometryHostThe shape or link.
hitPoint
Type: Microsoft.VisualStudio.Modeling.Diagrams.PointDThe point to test, relative to the bounds of the shape.
hitTestInfo
Type: Microsoft.VisualStudio.Modeling.Diagrams.DiagramHitTestInfoThe object that will receive the results of the hit test.
includeTolerance
Type: System.Booleantrue to include additional tolerance around the shape geometry when the hit test is performed; otherwise, false. If true, the test will result true even if the point is slightly outside the shape, unless there is a sibling shape directly underneath.
Return Value
Type: System.Boolean
true if the shape geometry was hit; 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.
