I have recently found out that the future of Qt has become uncertain as Nokia, It's current owner, has announced they officially have no interest in desktop Qt.
I know that Qt could survive by several different events but as I'm worried about learning a dying framework in terms of OS support and so I would like to learn another cross-platforn application framework a lot like Qt.
It needs to be cross-platform and contain many classes like Qt for development as well as a solid GUI library. I would like it to be very stable and well supported by OS's and IDEs
WxWidgets has modeled It's self too much on win32 and is very un-intuitive and window layout is very in-stable
Gtkmm models to much like a wrapper, as it is, to Gtk and documentation of it is some what non-existent. It also has little application classes so I would have to look around for other cross-platform libraries as well. It's signal slots implementation is no match for the ease and simplicity of Qt and Qt's thread support is amazing.
My only fear is if no company or massive community picks up Qt it will slowly loose compatibility to windows, new Linux kernels, Xorg releases, mac updates.... I would hate to watch this happen as Qt is an amazing framework
