Leadtools.Annotations Namespace > AnnGroupObject Class : HitTest Method



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 lenght of "buffer" * 2. This square is used to hit test.

Performs hit-testing on this AnnGroupObject object.

Syntax

Visual Basic (Declaration) 
Overrides Public Function HitTest( _
   ByVal testPoint As AnnPoint, _
   ByVal buffer As Integer _
) As Object
Visual Basic (Usage)Copy Code
Dim instance As AnnGroupObject
Dim testPoint As AnnPoint
Dim buffer As Integer
Dim value As Object
 
value = instance.HitTest(testPoint, buffer)
C# 
public override object HitTest( 
   AnnPoint testPoint,
   int buffer
)
C++/CLI 
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 lenght 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.

Requirements

Target Platforms: Microsoft .NET Framework 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family
