#qt6 — Public Fediverse posts

Qt 6.12 introduces a new way to provide QML controller objects using externally supplied singleton instances.

With QQmlEngine::setExternalSingletonInstance, declarative QML registration can now use application-provided singleton instances while preserving tooling and optimization benefits.

I’m happy to introduce Boutronique! 🌊🎹

It is a simple, lightweight utility designed for musicians and audio makers to identify and extract perfect loops from audio files without the complexity of a full DAW.

Built with the KISS principle in mind, it’s all about speed and focus.

✨ Key Features:

* Precision waveform looping & instant preview.
* Automatic BPM detection & manual adjustment.
* Optimized for the Torso Electronics S-4 (48kHz/32-bit export + auto-BPM naming).
* Open Source (Qt6/C++).

Give it a try and let me know what you think!

PSA for #Qutebrowser users (#Qt6 #Webengine based): we need to use this option to enable #kerberos support in `~/.config/qutebrowser/autoconfig.yaml` (for example, if you're a @fedora package maintainer and don't want to have to keep re-logging into Fedora websites):

```
qt.args:
global:
- auth-server-allowlist=*<domain>
```

Used to be `auth-server-whitelist` but changed at some point.

https://thoughts.greyh.at/posts/celestial-gtk-theme/

@zquestz published an article on Gtk theming which I found fascinating. It is an overview of the kind of things you have to consider when trying to create your own theme for #Linux . He fusses over the little details that are very important when doing UI/UX design properly. He also made sure the themes worked properly on various Gtk desktop environments, including Cinnamon, MATE, and Xfce (three of the best DEs, in my humble opinion).

He also mentions the qt6gtk2 plugin for Qt which I did not know about. It translates Gtk themes to Qt themes so all of your applications, whether they use Gtk or Qt, have the correct theme. This is extremely useful since the impedance mismatch between Qt and Gtk is the biggest source of UI/UX inconsistencies in Linux apps.

Руководство по сборке Qt под Windows из исходников с MinGW

Официальный способ установки готовых бинарников Qt - через онлайн инсталлятор. Однако он требует обязательной регистрации. Да еще и недоступен на территории РФ. Есть и другие способы получить бинарники, или собрать с компилятором от Microsoft , однако не всегда эти способы приемлемы. Сборка из исходников под Windows может оказаться несколько нетривиальна для новичков, потому сделал небольшую инструкцию по сборке Qt 5 и Qt 6. А так же рассмотрена базовая настройка QT Creator.

Yay, finally all the pieces have come together and I have finally been able to compile Qt 6.9 and @kde Plasma development version (what is to be released as 6.4 in June) for my @bananapi BPI-F3, a RISC-V single-board (mini) computer. Plasma does start and run, but looks like QML/QtQuick applications (which includes the desktop itself) have rendering problems 😞 Qt Widget apps render/run just fine. Now to figure out where the problem is…

Средства диагностики Плагин для Qt Creator Qt5 и Qt6

К сожалению, в Qt Creator нет таких же удобных диагностических инструментов, как Visual Studio Diagnostic Tools. Поэтому, для удобства, многим удобнее было бы пользоваться разработанным плагином DiagnosticTools для Qt Creator (Qt5, Qt6), в котором вы можете получить подробную информацию о разрабатываемых приложениях во время отладки кода.

I have a very weird memory bug in python or QT6. I add a few thousand rows to a QTableWidget. That works just fine, but if I first move the window, and then add the rows it takes a long time and memory usage goes over 40gb.
And it triggers only on the Mac I'm developing on. Other Mac with the same OS version, same python version has no problem.
On the dev Mac I tried different python3 version, created a new venv, but nothing helps.
tracemalloc doesn't seem to see the huge memory usage.
Any ideas on how to find the cause of this? I'm out of ideas.

It has been over three years since my last #Koto development diary. With its resurrection using #Qt6 and #KDE Frameworks, time to read why the heck I resurrected it to begin with and catch up on what I accomplished so far!

I plan on following up with a new entry in my "Dev Diary" before end of month. I had 12 updates in that series when it was GTK3/4 and I think rounding out what I've done in late Sept. and October leveraging #Qt6 and #KDE Frameworks would make for a good new entry.
