8 months ago So, I managed to figure it out. However, it's a little problematic, see here for the implementation. It needs to be created after the item that it's attached to (in order to display correctly), but because I can only run it on the public WmCreate, it gets created after all the other elements, resulting in the last one (a button in this case) getting attached, which changes its text to 0 and its size becomes smaller to fit, which is rather annoying to fix.

I'm currently trying to implement it my self, it's a little annoying cause I can't repurpose the
_NativeControlBase(thecreateWindowfunction is private... Actually, for that matter, it seems your API is rather hostile to user components).
