I have Gtk+3 already installed as it was with the distro. I need to use gtk+2 and glade. How do I use glade with gtk+2 and still have both gtk2 and gtk3 installed on my linux box? I have Glade 3.12.2 installed and when I save a project then open it in a text file it shows gtk 3 and need for it to say gtk 2 not gtk 3. 
glade gtk+2 and gtk+3
gtk;gtk2;gtk3
