Qt 4.6 has been released yay!<\/p>\n
A while ago i received from Nokia a cute Dell Latitude Xt2 multitouch tablet pc, to produce some demos of a really really nice new feature of Qt 4.6: multitouch.<\/p>\n
Qt provides two ways to acessing multitouch: one more abstract, where the type of gesture and direction of fingers movement already “parsed” so you already know if the user wants to zoom, scroll or rotate, that’s QGesture<\/a> that’s useful to control for instance scrolling and zooming in a web browser.<\/p>\n If you want instead something more raw, the position of every finger now and on the last sampling, you have instead QTouchEvent<\/a>. That’s useful if you want for instace paint with multiple fingers on a paint program or want implement some weird type of gesture not provided as stock. oh, and no It’s a rather different (and more simple) concept compared to Multi pointer X, since is a single event with multiple positions, rather than multiple simultaneous events.<\/p>\n So I tought that in KDE we have soe things that would make as an impressive demo with multitouch, so why not give it a try with Marble and Plasma :). So that’s the result (thanks to the trolls for the final edit):<\/p>\n
