My guess is that his question has already been asked, but couldn’t find it in the forum.
The code editor provides a way to contract or expand block of codes for if, for etc, clicking on + or -. This is automatically managed. I was wondering if one can create a custom block of code with that feature, that would expand or contract. For example in .Net you can do this with #region and #end region, or something similar. Can this be done in Xojo ?
