Thanks!
Yes I know about Squareline.
But I don’t need ready software.
I want to integrate LVGL into my custom C# software to get functions similar to Squareline, but much simpler (only 2-3 widgets needed, no styles, no code generation, just place and set positions of some widgets).
Or if not possible to do so, create new such software from scratch (windows only ok).
So I hope someone can point out easiest way of achiving this.
