- QT is a great and very-well designed library with solid performance, a fast release cycle and superb documentation.
- It provides a rich and well thought-out component library.
- It is used by many companies to build real-world applications.
- It has a pretty liberal licensing scheme. The commercial license (if you need it) is not that expensive.
- It provides bindings for many scripting languages like Python.
- It has great IDE support and lots of tooling around the core library that make GUI design easier.
- It emabraces model-driven design and has stylable components (via CSS).
- It will usually beat most JS / WebKit based frameworks by a large margin performance-wise and makes distribution of your application much easier (forget about >100 MB downloads).
FWIW its version of CSS is just terrible, there are a lot of properties you cannot control with it (e.g. display properties), its style inheritance model is equally terrible (for some reason if you do .foo, the foo object will get the style as will all of foo's children), and forget about animations. To be fair, I did test it out at v5 and they may have improved it, but at that time it was by no means a fair thing to call it css.
