HitTest Method (AnnGroupObject)

Performs hit-testing on this AnnGroupObject object.

Syntax

Visual Basic
C#
Objective-C
Java
C++

public override object HitTest( 
   AnnPoint testPoint,
   int buffer
)

'Declaration
 
Public Overrides Function HitTest( _
   ByVal testPoint As AnnPoint, _
   ByVal buffer As Integer _
) As Object

'Usage
 
Dim instance As AnnGroupObject
Dim testPoint As AnnPoint
Dim buffer As Integer
Dim value As Object
 
value = instance.HitTest(testPoint, buffer)

public:
Object^ HitTest( 
   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 Visual Basic) 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.
