Re: [Interest] QTouchEvents correctly placed only when the windows is on the primary screen?
Anyway, I think global touch coordinates should be w.r.t. the desktop, not the screen. If you want to simplify and say that tuio only permits mapping the touch area to an entire screen, you can still offset the coordinates according to the screen's position on the desktop. This approach does make sense to me, but since we are talking within Qt, can or does Qt do something like this behind the scenes? And by that I mean in a cross-platform fashion without you having to notice or bother too much (apart from some tiny bits of configuration, of course, with which I'd be totally ok). -- Andrea Franceschini ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
[Interest] QTouchEvents correctly placed only when the windows is on the primary screen?
Hi there. I'm using qtuiotouch but this might be a more general issue I'm not aware of. Basically my set-up is like this: - primary screen: regular desktop screen; - secondary screen: huge touch screen sending out TUIO messages. I set up a small QGraphicsView/Scene example to figure out a few things and then I noticed that I wasn't getting touch events if the GV windows wasn't on the primary screen (no matter which one). So I couldn't move the window on the secondary touch screen, go to full screen, and do the touch-thing, but if I kept the window on the primary screen (desktop) it would work as expected, meaning that the TUIO messages got perfectly mapped to the GV/Scene. Now, a temporary solution would be to make the touch screen my primary screen, which is doable but highly annoying, especially since I'm working on a Mac, I might need the menu bar some times, and the touch screen lies horizontal on a table (not exactly visible from a sitting position). Ideas? -- Andrea Franceschini ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
Re: [Interest] QTouchEvents correctly placed only when the windows is on the primary screen?
Hi, Well, the short answer is that qtuiotouch assumes that the touch screen is the primary (only) screen. There are two questions that need answers before I could support your configuration: 1. How to associate the TUIO device with the correct QScreen? (maybe QScreen::name and the TUIO device name) 2. How is QWindowSystemInterface::handleTouchEvent supposed to handle multiple screens? ~Dan -Original Message- From: interest-bounces+daniel.casimiro=navy@qt-project.org [mailto:interest-bounces+daniel.casimiro=navy.mil@qt- project.org] On Behalf Of Andrea Franceschini Sent: Wednesday, September 25, 2013 12:06 PM To: interest@qt-project.org Subject: [Interest] QTouchEvents correctly placed only when the windows is on the primary screen?

2013/9/25 Casimiro, Daniel C CIV NUWC NWPT daniel.casim...@navy.mil: 1. How to associate the TUIO device with the correct QScreen? (maybe QScreen::name and the TUIO device name) 2. How is QWindowSystemInterface::handleTouchEvent supposed to handle multiple screens? That's actually the same thing I was wondering. As for 1, I'd say that sounds plausible, but is it feasible? As for 2, in my case I don't need multiple touch screens, but I suppose that you could somehow extend the approach from 1, maybe via on/off-line config? -- Andrea Franceschini ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
