Thread: Which toolkit should I use: gtk2+ or gtk3+?

Hi,

I was writing a program (about 500 lines) that makes use of some old openGL 2.1 graphics using C and freeGlut. The reason I used openGL 2.1 is simple: most tutorials on the net refer to it. Then I realized it would be better to include a GUI, so having the code written in C, I can only go for GTK. But then there is the problem: GTK3+ does is incompatible with openGL2.1 code (halting problem : Using OpenGL with GTK+ ). So I would need to go to GTK2+. But going to GTK2+ is going backwards is it not?

What do you guys recommend? Here are a few options:

1) Should I learn new openGL and use state-of-the-art GTK3+

2) Just learn GTK2+

3) Well, just convert/rewrite your C code into C++ and use Qt as it is cross-platform (GTK3+ is not so great in that aspect) and can achieve some wonderful results.
