Where to start?

[PiMaster]

Hi, I'm making a game engine called "ORLY v2" (v1 was an SDL wrapper that required a dozen DLLs), and I'm interested in making it compatible with Unix/Linux.

Because of this, I'll need to find documentation on the GUI for Unix/Linux. Can anyone point me to it?

[JoR]

There is no such thing as the GUI for Unix/Linux. Most is done through commands and scripts. Though there are IDEs and everything on Linux and other Unix derivates as well, people tend to use Makefiles when developing software.

There's no Unix/Linux equivalent to WinAPI? Or am i misunderstanding...? O.o

[Kyon]

There is no explicit "Linux Gui", most applications use the cross-platform Qt4 API.

I think I misunderstood you then, however no, there's not. What do you need?

[PiMaster]

I need an API that provides functions for creating/manipulating windows.

[EzwRko23]

Of course there is: there is the X-Window System API.
You can find the documentation here: http://www.xfree86.org/

But it is very low-level (just as WinAPI is), so
most programmers use higher-level libraries like GTK or Qt, which are much easier.

[PiMaster]

Ok... Is it faster than GTK or Qt? Or is it not worth the effort?

[Albatross]

For me at least, the speed gained from coding using X11's lower-level API when I can use Qt is not worth the effort.
