Lopes - I did a lot of live video work using Qt in a project I have on Google code: https://code.google.com/p/livepro/
I havn't tried it with Qt 5+, but it was all with Qt 4.8. Let me know if you have any questions on that if you actually do look at any of the code. Thanks! -Josiah On Mon, Mar 31, 2014 at 6:52 AM, Lopes Yoann <yoann.lo...@digia.com> wrote: > > On Mar 28, 2014, at 7:41 PM, Tom Isaacson wrote: > > > I'm working on an app that reads data from a sensor then displays it on > a graph using qwt.
