worked with GTK2&#x2F;3 and QT 5+ years and got the feeling that GTK has been turning into the GNOME toolkit as well. not very pleasant to work with if you want your application to support the look&amp;feel of different linux-DEs and not suited for cross-platform applications at all<p>GTK3 is perfect if you want to develop for the GNOME desktop. for anything else it would need way more developers that are not focused on GNOME
