WIMP Programming - Window Furniture

I used, for example, DrawfileRender and so it’s not compatible with the earlier versions of RISC OS as things stand.

Don’t let that statement hold you back – there’s a softloading DrawFile module in !System so just RMEnsure as needed (and RMLoad System:Modules.DrawFile if not already loaded), I’d expect most people still keeping a 3.10 machine alive will probably have a copy in their Boot.
