HitTest Method

public virtual bool HitTest( 
   LeadPointD location,
   LeadPointD testPoint,
   double hitTestBuffer
)

 function Leadtools.Annotations.Rendering.AnnThumbStyle.HitTest( 
   location ,
   testPoint ,
   hitTestBuffer 
)

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.

Return Value

The automation framework will call HitTest 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.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
