how to get the last element of findAll

sort the resulting matches appropriately and select the one that you want by index.

solution for Python: http://doc.sikuli.org/region.html#Region.findAll

Sorry I didn't see this page before.

Thank you,

elements = reg.findAll("checkbox.png")
last_element = sorted(elements, key=lambda x:x.y)[-1]

Until yesterday this worked as expected, which means the right last element is returned, but sometimes it returns another element which obviously is not the last one in the list.

How can I make sure I'm getting the last one?

as far as I understood your setup, the checkboxes (cbx) are arranged this way:

(cb1) some text (cb2) some text (cb3) some text

(cb4) some text (cb5) some text

supposing, they are vertically aligned (same y value for cb4 and cb 5), than it is not predictable, that always cb5 is sortedList[-1], it might be sortedList[-2] (so it might depend on air pressure or something similarly random ;-)

so you have to sort the last two values according to their x value.

or use a lambda like this:
last_element = sorted(elements, key=lambda element: element.y * 10000 + element.x)[-1]

Nice :), works like a charm now, thank you RaiMan
