Oh of course. I was talking about embedded use cases (Automotive dashboards etc..), where it is just mostly moving around various textures, playing with colors/opacity etc... (Basically the GUI lvgl youtube videos are showing off: htt

Oh that sucks. Yeah Qt has gotten really aggressive with their licensing headaches. They broke so many of our CI scripts when they made it mandatory for you to log in to use their Qt installer even for online version. And yep. Relying on ju

Oh it really depends on your use case and the hardware you use for embedded devices. If all you need are some buttons and some kind of static lists, lvgl should be fine too. But for anything where you want things like smooth scrolling&#x2F

The big one being - when you install just an application, you don't want it to accidentally pull in the wrong dependency and destroy the rest of your system. This is a big problem when you use ppas or .debs directly from the app develo

Yep. It's a problem when building mobile applications too. Especially for iOS. Sailfish OS was stuck on Qt5.6 for a long time because of this.

The main problem with LGPLv3 is the anti-tivoization clause. That means you should basically provide the end user a way to replace the Qt libraries with their own. On embedded systems this can mean headaches for companies releasing commerci

With QML/QtQuick all/most of the ui is rendered on the GPU though. That leaves the CPU free to perform other tasks. Even at 1080p 60 fps your CPU usage sits under 10% on cheap iMX6 devices. With lvgl it looks like it doesn't

I feel you. In fact after a decade of mostly C++ / Qt jobs, I've realized it's time to move away to other tech. More companies i worked with are avoiding Qt where they can. And even i was getting tired of creating the same Qt

I honestly don't know. I mean i routinely see so many GPL violations too and all i had to do was grep the binaries/update packages for strings like GPL. All i can tell you is most of the small-medium sized companies i worked for o

I've used Qt for developing a few desktop apps, a couple of mobile apps and while working on a few embedded systems. The good: 1. Their QWidgets library is very stable and mature for cross platform desktop applications and i can still

It's still free under lgpl. Their open source version anyway. [1] Just that the Qt company lately has been trying everything to scare / annoy people into getting licenses, sign up for their online accounts etc... So they're j

LXC is needed to run the services that Android provides, for Android applications (Surfaceflinger, Audioflinger etc..) Android ships with it's own init system that does a lot more than just starting/stopping services. And integrat

I've worked on a couple of d-pad only uis using QtQuick, Including for a set top box. Gstreamer's qmlglsink works quite well with zero copy video playback. So CPU usage sits at 5-10% for a nice UI overlaid on top of a 1080p video

Hi, Not the maintainer of the above library, but this seems similar to a reverse engineered library for a couple of other chinese wifi quads. Someone created a chrome app for their specific model a couple of years ago, and their notes are a

Ahh interesting. Would love to see a comparison between gtk4 widgets vs. qtquickcontrols 2.0. From the looks of it, gtk 4 seems to have come a long way since I last tried: https://m.youtube.com/watch?v=slIhZwmMv1g And more

Could it be that heating issues are also because of the choice of their UI toolkit? It looked like they're writing their apps in gtk, using the CPU for any animation and rendering - as opposed to some OpenGL solution that would do this

Iirc Electrolux was working on a fairly similar concept back in 2012-2013. Can't find the exact link for the touch screen one but these demos should be fairly similar: https://m.youtube.com/watch?v=dK1IVk_NiGY# https:

How about contributing to a nice little opensource project? "I had weekly coaching sessions" - Pick/Create 1 Issue/Task every week :P "I would love to have guidance...." - Discuss your plans with the project maintainer/other contributors. "

At this point of time, i honestly believe that it was an open problem in the public domain, that any high school student could have solved (at least, when nudged in the right direction)... And I am pretty sure that a lot of people have come
