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 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.
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 DefaultHitTestValue.
To find the object inside the group that satisfies the hit-test, enumerate all of the objects in the group and call HitTest manually.
For more information, refer to HitTest.
