Embed into existing SDL app #533

Open whitebyte opened 6 years ago

whitebyte commented 6 years ago

Hi, is there any way to embed DlangUI into existing SDL2 app and create widgets inside preexisting SDL window (not made by DlangUI)? I already have a window and a main loop in my app, and I want to try to plug-in DlangUI into it, but after the quick skim through examples I have an impression that DlangUI only works with it's own created window and context. I remember some old threads on forum.dlang.org regarding similar question, but don't know if it was answered or not.

It's possible, if you implement Window and Platform for working as SDL2 embedded.

Could you please elaborate? Or maybe give some minimal example?

DSFML backend is example of embedded implementation. It has window and platform classes implementation to work with external event loop and externally created windows/surfaces. It looks like new SDL_EMBEDDED configuration needs to be created based on SDL platform implementation reworked similar to DSFML.
