It would be very interesting to see QEdje widgets such as those used in Canola and during the QEdje presentation at Akademy to be easily used in Plasma. The standard qt style that's used on the desktop doesn't really work for a touchscreen device, those that I've seen and used in Canola work quite well. In Plasma, we have a couple of widget classes (Plasma::Label, Plasma::Button, Plasma::Slider, ...) that are currently restyled versions of QWidgets, loaded as proxy widgets. We could also use these wrapper classes and present them with the same API to the applets. With some sort of switch (config?, compile- time?) we'll have the applets use the qedje widgets instead (and with them their interaction models that are optimized for a certain set of input devices). I've been working on a small applet for MID devices that presents sliders for brightness and volume, and I noticed that those QWidgets in their current form won't work really well on touchscreen devices -- no surprise, they're made specifically for mouse + keyboard use. One could also thing of offering widgets styles through gethotnewstuff (an installer for addons), putting the .edj files in themes (and adding them to the plasmagik packaging tool). > I am all eyes to any information you guys think would be relevant for me to > know, and I will try to catch up with what you guys have in mind asap and > contribute to it in the best way possible! During the Akademy talk, it was said that QEdje would be fast enough for desktop use already. I've installed the applet, and it works well here :) Two days earlier, the trolltech qgraphicsview guys have shown some nice performance improvements in QGV's clipping mechanics, maybe that'll help improving the performance further. Zack Rusin has been looking into hardware acceleration of Qt's drawing, his benchmarks are quite interesting: http://zrusin.blogspot.com/2008/08/fast-graphics.html > Cheers from Brazil, Cheers, -- sebas http://www.kde.org | http://vizZzion.org | GPG Key ID: 9119 0EF9
