This is a very good question. The answer is that it depends whether or not you add #1 (or #2, #3,…) to your image name:
-
Without #1 (e.g.
XClick | image.png
) UIVision sorts after best match. So if the 3rd checkbox in this list happen to be a slightly better match than the others, it will be number 1 in the order. -
With #1 added (e.g.
XClick | image.png#1
) UIVision treats all matches above the confidence level as equal. It sorts as top/left to bottom/right. So if the 3rd checkbox in this list happen to be a slightly better match than the others, it will still be number 3 in the order. So this is what you need.
