− Goya is so nice mainly because it integrates pretty well with the Model/View design, and uses the Qt powerful signals and slots. Goya widgets will emit signals when something have happened to them, so you will be able to connect those signals to your app slots, and do fancy stuff without complex stuff. + Goya is so nice mainly because it integrates pretty well with the Model/View design, and uses the Qt powerful signals and slots.
