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

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.
