HitTest Method (AnnGroupObject)
Summary
Performs hit-testing on this AnnGroupObject object.
Syntax
public override object HitTest(Leadtools.Annotations.AnnPoint testPoint,int buffer)
Public Overrides Function HitTest( _ByVal testPoint As Leadtools.Annotations.AnnPoint, _ByVal buffer As Integer _) As Object
public:Object^ HitTest(Leadtools.Annotations.AnnPoint testPoint,int buffer) override
Parameters
testPoint
The AnnPoint structure that contains the point to test.
buffer
Value that represents the size of the test point. This value makes the test point a square with an edge length of "buffer" * 2. This square is used to hit test.
Return Value
The AnnObject.DefaultHitTestValue if any annotation object within the group satisfies the hit test; or null (Nothing in VB) if the test point does not hit an annotation object in this AnnGroupObject object.
Remarks
The AnnGroupObject will perform hit-testing on all the objects in the group. If any annotation object within the group satisfies the hit test, the return value will be AnnObject.DefaultHitTestValue. To find the object inside the group that satisfies the hit-test, enumerate all of the objects in the group and call AnnObject.HitTest manually. For more information, refer to AnnObject.HitTest.
