Qt Animation framework
I've been working recently with Qt Animation Framework , trying to learn how to utilize it efficiently. Below is a video showing circular carousel widget which uses the animation framework. I need to still continue experimenting how to really extend the animation classes and use the whole state machine framework, but so far I'm impressed by the latest 2.2 API version. Originally my biggest concern about this whole "Kinetic" was that it would be too high-level and have suboptimal performance in embedded devices, but luckily that doesn't seem to be the case. Now with Qt 4.5, QGraphicsView starts to be very usable also in N810 and one just needs to know tips & tricks how to utilize it efficiently. Below is the same carousel widget in N810, using the "raster" graphics backend: FPS up there means how many times QGraphicsView paintEvent() is called, so it drops when more drawing to view is needed, but stays quite healthy & usable anyway. Back to coding...
