Well that stuff falls under the
ZScript menu territory which is the hardest concept out of everything that ZScript allows.
Additionally, as I've written in the comments of the ZScript source, I did it in a very backwards way - I specifically checked for each and every selector position to determine which help text to display.
Ideally, what should be done is to extend the widget to take in an additionall "tooltip" argument. My head was a little blurry back then when I made this and I didn't know how to make custom arguments for a widget's Init, but I know how to now... it'll most probably be in the next update of Tilt++.
But to answer your question: no, currently there are no tutorials. And as has been said in the Major Cooke thread I linked... unfortunately, ZScript menus are VERY hard and it has a very steep learning curve and requires the user to have a fairly solid grasp on advanced programming topics.
The best anyone can do around here currently is to answer specific questions pertaining to specific situations, but truth be told, they'll most probably always end up looking like
my answer here.
Menus are very powerful, you can do some crazy stuff with it... I just started doing a
menu overhaul yesterday but boy was it not a pleasant experience.
I am hoping that when the dust settles down and people's skill level with ZScript have improved (mine included), there will at least be a possibility to do a step-by-step "here's how to make/edit menus". I mean right now, to be honest I don't even fully understand some of the shit I've been doing. I don't want to spread misinformation.
