@ZinoSama, if you want to do a lot of little animations, you could take a look at scripter (blows dust off the link). With it, you can have several simultaneous and long-running animations without having to worry about the UI thread.

An example of a button click handler running a counter to 100:

@script def start(sender): label = sender.superview["label1"] set_value(label, "text", range(1, 101), lambda count: f"Count: {count}")

You can't put this sort of loop inside a button action, unless the action has in_background.

@cvp, I was pretty sure, given ”1 post” and the content, until I saw the other post. My apologies @roku_one.

Thank you so much! That is exactly what I was looking for.

@FrankenApps no problem, often not easy to search in forum, better to search via google 😃

@JonB You are the man. It was how I had flex set up.

@b1rchy, I think no, not easily. Thus you might consider e.g. placing a Label inside the Button, and change the text of that. Or go off the deep end and see if there is something in the underlying ObjC UIButton to help you.

Anyway would be to propose None is iterable 0 times , LOL, not thought out that comment 😁
