Spring RTS Engine

With help of dudes i found this is actual handler: https://github.com/jk3064/new_widgethandler, but it looks like, no game is using it, yet. Z-K is using own custom handler as from inspection of other maintained games, rest is using some few years old handlers.

Thats sad, because with old one im not able to use all cool new features, cool call-ins, that i need for widgets and gadgets.

I tried to make comparation with old handler, tried to copy full folder to my game file ./LuaUI, tried use just some combination of files, but new callins are not working, still. So Im sure i do something bad.

Can you please describe some basics of this move? For example, what i should do with files (on link above), which files i should use and where should be those files placed. Thx

95.0 will got it in the basecontent where you can include it from

So theres no simple way how to include it in spring 94.1? Thats why no game use it, yet?

Pls when 95.0 is out, make some thread about this update.
