Qt Framework

As part of this expansion, Qt Group will introduce new bridging technology that integrates Qt with any programming language of choice, initially including Rust, Python, .NET, Swift, and Kotlin/Java.

I'd really like to use Qt for GUI and HMI development for certified medical devices using embedded hardware, but wasn't looking forward to all the conventional C++ that would have entailed. Looks using Rust with Qt may get better soon?

Second source reporting from Qt World Summit in Munich:

Part of the thinking here is that C++ is regarded as an unsafe language whereas the languages supported by Qt Bridges are safe languages, potentially escaping the notion that because Qt is C++, it is not as safe to use.

KDE Frameworks are 72 addon libraries to Qt which provide a wide variety of commonly needed functionality in mature, peer reviewed and well tested libraries with friendly licensing terms. For an introduction see the KDE Frameworks release announcement.

I've been trying to style my Qt apps since I discovered the old Motif-look Style Plugin still exists; maybe I can have software not made in 1994 that looks like it was!

In the process, I noticed an odd behaviour.

I set up QT_QPA_PLATFORMTHEME=qt5ct so I could use qt5ct to do the basic configuration.

If I set the "general" font as bold, and the "fixed width" value as non-bold, when I reload qt5ct, it's switched to bold. This can also be seen in other Qt programs.

If I manually force the issue by editing qt5ct.conf, manually setting up a block like this, the bold fixed-width font still shows

[Fonts]

fixed="Go Mono,11,-1,5,75,0,0,0,0,0,Regular"

general="Helvetica,11,-1,5,75,0,0,0,0,0,Bold"

I thought this might be some weirdness due to the specific fonts I chose, but swapping in "Liberation Sans" and "Courier 10 Pitch" produce the same situation.

The only way I can have my fixed-width font be "regular" is to also leave the general font as "regular". This is not a connection I expected.

Is this a known issue? Is there a workaround?
