c++ & Linux

Well, for windows gui's you know how there is windows.h, well, is there something like linux.h for linux gui's?

There are lots of GUI toolkits for linux. The two most popular are GTK and QT. QT is free for use in open source applications, so don't let the "evaluation" button fool you.

There is also a C++ wrapper for GTK called GTKmm (or GTK--), which wraps the C functions into C++ objects.

You can try here.

Thanks... :D
