GTKmm or GTK+ ???
 

I wrote a program using Qt while ago. But I forgot to backup my program files before a system recovery. I found out Qt is easy to use, but has many other problems. Now, I decided to use Gtk. The problem is should I use Gtk+ C or GTKmm C++?? Any suggestion is welcome!

Well, clearly, if you wanted to program in C you would use GTK+ and if you wanted to program in C++ you would use GTKmm. There's not much else you can be told :-P

Actually, I prefer to code my application in C++ ... while still coding straight to the GTK+ API. Less overhead, simpler (IMHO).

In any case, you can definitely code to GTK+ from C++ should you choose to do so.
