[Interest] Replacement for Qt4 QMatrix4x4?

2019-02-21 Thread Matthew Woehlke
So... after a full day of debugging, trying to port my Qt4 app to Qt5 and chase down a nasty case of stack clobbering, I discovered that the problem is that QMatrix4x4 changed from qreal to float. (Uh...why? I am not particularly amused by the loss of precision, nor the extremely subtle

[Interest] Qt3D Vulkan back-end

Hi, Does anyone know about plans for a Vulkan back-end for Qt3D? Looks like there was some work started in the past ( https://codereview.qt-project.org/#/c/196945/ ) that was abandoned since. Thanks! ___ Interest mailing list Interest@qt-project.org

Re: [Interest] About subscription issues

This is definitely a sa...@qt.io question, but if both companies have the same developers, then I don't see why they would need two licenses?   It's an uncommon case that could be considered a loophole, as it's licensed per developer. The question is, is they key (company, person) or (person).

[Interest] About subscription issues

I have 2 LLC companies in the US. The company is only my own. If my two companies sell my own QT development software in the future, can I use only one of the company subscriptions? Of course, because of the pressure of life, I don’t consider buying now, but if I complete the development, I will

So there are only three licences: LGPL Commercial Commercial Runtime (Boot2Qt)   IANAL, but the dynamic/static linking debate is not even settled, even in court. I would say that the spirit of LGPL and existing precedent is that under LGPL you can't modify Qt without releasing it. If you

You're reversing the burden of proof here. Where have Qt stated that it is non-free for mobile? The licensing terms are the same no matter the platform; Qt is LGPL or Commercial. It's up to you to adhere to whichever license you choose to utilise. /René On Thu, 21 Feb 2019 at 14:50 Sylvain
