RenderHitTest Method

Summary

Queries the specified location to determine if a test point is over the thumb using the specified mapper.

Syntax

Java

Objective-C

WinRT C#

C++

public bool RenderHitTest( 
   LeadPointD location, 
   LeadPointD testPoint, 
   double hitTestBuffer, 
   AnnContainerMapper mapper 
)

Function RenderHitTest( _ 
   ByVal location As Leadtools.LeadPointD, _ 
   ByVal testPoint As Leadtools.LeadPointD, _ 
   ByVal hitTestBuffer As Double, _ 
   ByVal mapper As Leadtools.Annotations.Core.AnnContainerMapper _ 
) As Boolean

bool RenderHitTest(  
   Leadtools.LeadPointD location, 
   Leadtools.LeadPointD testPoint, 
   double hitTestBuffer, 
   Leadtools.Annotations.Core.AnnContainerMapper mapper 
)

-(BOOL) renderHitTestPoint:(LeadPointD)location 
           testPoint:(LeadPointD)testPoint 
              buffer:(double) aBuffer 
              mapper:(LTAnnContainerMapper*)mapper;

boolean renderHitTest(LeadPointD location, LeadPointD testPoint, double hitTestBuffer, AnnContainerMapper mapper);

function Leadtools.Annotations.Core.IAnnThumbStyle.RenderHitTest(  
   location , 
   testPoint , 
   hitTestBuffer , 
   mapper  
)

public:  
   bool RenderHitTest( 
      LeadPointD^ location, 
      LeadPointD^ testPoint, 
      double hitTestBuffer, 
      AnnContainerMapper^ mapper 
   )

Parameters

location
The location of the thumb to test in container coordinates.

testPoint
The point to test in container coordinates.

hitTestBuffer
The hit test buffer is used to make the test point "bigger" to compensate for errors and provide smoother hit-testing. For example, if the buffer value is 2, a square with a length of 4 units around the test point will be used to perform the hit-testing. This value is in container coordinates.

mapper
The mapper object to use for converting coordinates. This value must not be null.

Return Value

true if the specified test point is over the thumb; otherwise, false.

Remarks

The automation framework will call RenderHitTest repeatedly to determine if a user input location is over a thumb. For example, to determine if the framework should start dragging a side of a selected object or to start rotating it.
