Cross Platform C library for GUI Apps? [closed]

Answer 1

One that I have considered using was the EFL, as it's quite fast, simple, small, but powerful. I would recommend diving into Elementary, their simplest GUI toolkit, and then later on, once you get comfortable with it, move to EDJE, which is not as simple, but much more powerful.

Answer 2

If you are looking for a C++ library, then Qt basically does what you are looking for. If you want to stick to pure C, then Qt is not an option.

As a C framework you could use GTK+, it works on Linux, Windows and OS X.

Answer 3

Qt is a C++ library. Other cross platform libraries that you might consider are wxWidgets (C++), and GTK (C).

All three of the presented libraries are fully cross platform. You can also look at Tcl/Tk, but that's a toolkit :).
