renderHitTest Method (AnnThumbStyle)
Summary
Queries the specified location to determine if a test point is over the thumb using the specified mapper.
Syntax
JavaScript Syntax
AnnThumbStyle.prototype.renderHitTest = function(location, testPoint, hitTestBuffer, mapper)TypeScript Syntax
renderHitTest(location: LeadPointD, testPoint: LeadPointD, hitTestBuffer: number, mapper: AnnContainerMapper): boolean;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. 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.
