Hello,
I was wondering whether Qt3D could be well suited to implement a position-
and camera-based augmented reality system. Would it be trivial to
synchronise the camera, sensors and drawing with current APIs or is a lot
of work required?
Could it also be done in QML?
thanks

Yep, thanks for pointing that out, and indeed

I'm not sure what roles gets me? Since I'm trying to display a read-only

Hi!
I was just playing around with the "Accessible" attached property and
Mac OS X Voice Over as a screen reader.
The result: It doesn’t work at all.
Neither the focus rectangle is properly displayed nor does changing
the focus trigger any status update on the accessibility side.
I’ve also

Basically I want to just show the raw XML file, in its entirety, but allowing
the
user to expand/collapse the XML nodes.

Im playing with the new Bash/WSL for windows 10, and want to create a Qt
package.
There is no X available, its only CLI based, what configuration options are the
best for this setup?

Hi. I've been reading through the documentation and mailing list
archives and I haven't found an authoritative and/or conclusive answer to
the following question:
What exactly is the relationship between an event loop entered by
calling QEventLoop::exec() and *the* main event loop (the one

Both functions as well as QThread::exec() are
