I've been doing quite a bit of Googling on the subject and haven't found any definitive answers, so I thought I'd ask here before I just go any try every available option... Maybe someone can save me quite a bit of time!
I'm working on an embedded project and am looking for a modern GUI framework to control it via touchscreen. Hoping to avoid running a window manager and use the framebuffer, or perhaps X with a composite manager alone, but that's not a requirement if it causes difficulty.
I'm hoping the Pi Foundation's DSI display come outs around the time I'm finished, so I'm looking to eventually make use of that. I've looked at GTK+, Qt, HTML5, PyGame, Kivy, and a host of other UI frameworks. Before I go and try to code a test in each and every one, I'm wondering if anyone has any experience with modern UIs on the Pi?
Basically looking to have something that's pretty to look at all day, as it'll be visible most of the time. The interface will be displaying a set of default data as well as the need to switch between other sources of information, so I'm looking for some smooth transitions, transparency, etc. Doesn't need to be at the functionality of, say, iOS or Android, but if I can fake it for a few screens I'd be happy.
I haven't found any plug and play frameworks that are guaranteed to run smoothly on the Pi. The ones that do don't seem to have much of a UI framework, and starting from scratch is a bit beyond my skill and time available.
Question comes down to this: Can I get a modern UI to run smoothly on the Pi without starting from scratch? Does anyone have any recommendations and or examples? Apps running on the Pi with modern UIs in GTK+, Qt, etc?
Any help would be appreciated! Thanks!
