How to get the TextBox border to show

I don’t see any examples in the documentation. For example, under TextBox properties, the API reference says:

“border - string
The border of this component

do I put a character in there, an ascii value, True? not sure where in the documentation I see examples, or even a more thorough explanation.

Hello,

This post might be helpful:

For example,

solid black 2px

very helpful - were the docs updated and I missed it? I see the post is from 2017

I’m not sure although when I search the docs for “border” I get a pop up explaining some things briefly. I hope this helps.
