I'm trying to write some apps for Nokias N9 with Qt Quick and all I seam to get is a lot of bugs from the libraries. I had better experience with X that is to say less bugs but a lot harder programming. FLTK is also buggy. When I chose GTK over QT I probably made a good choice since GTK is not that buggy with my experience even if i had to program around some bugs. Their seam always to be bugs and the time consuming thing is to program around these bugs specially in the case of qt quick.

So to my question? When i'm going to develop apps for android, windows phone, blackbarry, bada and iphone are those libraries buggy(as hell - Qt Quick) or are they like GTK(almost 100%)? Any experiences you would like to share?

Buy the way now I get it why Nokia went the Windows road.

I haven't used Qt Quick, but Qt with QWidget has been rock solid for me.

BTW, are the Qt Quick bugs that you've found currently in their issue tracker? If not, report them. Qt Quick is still very much an emerging technology.
