I don't know if being a FLOSS project leads to that. The only aspect I referred to was the ability to learn how Qt works and to share any fixes and changes with anyone that the FLOSS license grants. >> - C++ > > Please help explaining this further (as I'm not a C++ developer myself). > Also we need to explain this next to QML, Javascript and HTML5 Personally, I don't care for Javascript and HTML5, and I'm yet to see any usefulness in QML.

Personally, I'm ok with the idea of Qt being C++ only, and only a GUI toolkit. >> - signals& slots (aka observer pattern) > > Help explaining the beauty of this functionality compared to other > toolkits is appreciated. Again, how to explain how great this is to a > newcomer? The observer pattern isn't exclusive to Qt, nor is event handling. Qt's way of doing signals & slots tended to be easier than the way callbacks were typically handled. I don't know if it is still true today, as some FLOSS callback systems which popped up recently, such as libsigc++, are, in my opinion, superior to Qt's offering. Qt's offering may be seen as a bit more resilient when dealing with errors introduced by the programmer, but I suspect that this is mainly due to the fact that some programming errors fail silently instead of returning a long and nasty compiler or runtime error. This isn't necessarily better or worse, as it can be seen as being both depending on the scenario. >> - cross-platform GUI toolkit > > This one is now addressed at "Cross platform = multiple targets& user > sectors" > > >> It also helps that Qt's default widget styles are easy on the eyes. > > "Good quality, easy to read code"? I was referring to how Qt applications look. Plastique looks nice, for example. Qt also provides an interesting set of widgets.
