HitTest Method (AnnObject)
Summary
Performs hit-testing on this AnnObject.
Syntax
public virtual object HitTest(Leadtools.Annotations.AnnPoint testPoint,int buffer)
Public Overridable Function HitTest( _ByVal testPoint As Leadtools.Annotations.AnnPoint, _ByVal buffer As Integer _) As Object
public:virtual Object^ HitTest(Leadtools.Annotations.AnnPoint testPoint,int buffer)
Parameters
testPoint
The AnnPoint to be tested.
buffer
Threshold buffer value, in pixels.
Return Value
A value that represents the hit-test value; or null (Nothing in VB) if the test point is not on top of this AnnObject.
Remarks
This method is called internally by the annotation framework whenever the HitTest method is called. You can call this method on the annotation object returned from HitTest to fine tune the hit-test value if applicable.
testPoint
The AnnPoint to be tested.
buffer
Threshold buffer value, in pixels.
If this AnnObject is invisible (Visible is set to false), this method will return null (Nothing in VB).
By default, an annotation object will return DefaultHitTestValue if hit-testing was satisfied. Derived objects can override this method to fine tune the return value.
Example
For an example, refer to AnnContainer.
