Which portable GUI and graphic library are supported to develop on Haiku (C library if possible)

[Kitsune64]

I have trying wxWidget apparently the port on Haiku are wxgtk_devel or wxqt_devel, i don’t find an issue to create an app with theses libraries.

I have also find it today in Haiku Depot Xlibe: a Xlib implementation for Haiku that use the Haiku API
(if I understand correctly).
See a post here about it:

Xlibe: an Xlib/X11 compatibility layer for Haiku

Everyone seems to be doing “progress threads” these days, so I figured I’d join the fun. And now I have something that seems uniquely suited to such a thread. To begin with, there was a note I made in my last progress report, about the potentiality of writing an “Xlib compatibility layer”, that is, an implementation of the X11 APIs without an X11 server… Some of you have already picked up on this (or seen my intermittent ramblings in IRC about it) and noticed the repository that has shown up …

I have try it and I can code in C with it, it’s interesting, and seem more simple to use/understand than gtk and maybe more lightweight.
