I took a quick look at some elements. From what I've seen, the appearance and positioning of the text are fine.

Thanks for your work, plc-user.

BTW:
It is possible but not needed, to edit the registry directly!
Changing the font-settings in configuration-page will do it for you!

It makes sense to ensure cross-system compatibility by providing a default free font that behaves consistently across Linux, MacOS, and Windows. Using Liberation Sans as the default is a solid choice since it closely matches Arial while being open-source.

Regarding implementation, hardcoding the default font settings in generalconfigurationpage.* seems like the simplest and most reliable approach. However, having an optional script to modify registry settings for Windows users could still be useful, especially for those who prefer manual control over font settings.

Additionally, updating the Elements Collection to align with the new defaults is a good idea to prevent inconsistencies. Defining clear replacement rules (e.g., Sans Serif → Liberation Sans, Times New Roman → Liberation Serif) would help standardize the transition.

Would it make sense to include these font settings in a configuration file instead, so users can override them without modifying the registry or code directly?

We need to inform the users, that we provide default-fonts for all systems from date x.
And we should also point out that the font should be chosen if users are thinking about or relying on cross-system data exchange.

Do we need to adjust the Elements-Collection, too?
This could be done with a small script, but we would need to agree on which fonts to replace with which others:
Sans Serif or Arial --> Liberation Sans
Serif or Times New Roman --> Liberation Serif
MS Shell Dlg --> ???

EDIT:
This should be it:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\QElectroTech\QElectroTech]
"diagramitemfont"="Liberation Sans"
"diagramitemsize"=dword:00000009
"diagramitemstyle"="Regular"
"diagramitemweight"=dword:00000032


[HKEY_CURRENT_USER\Software\QElectroTech\QElectroTech\diagrameditor]
"dynamic_text_font"="Liberation Sans,9,-1,5,50,0,0,0,0,0,Regular"
"independent_text_font"="Liberation Sans,9,-1,5,50,0,0,0,0,0,Regular"

Therefore:
We are on a very good way to solve this age-old problem!

Vous pouvez également inclure le fichier de police dans le répertoire QET.
D'autres programmes de dessin font de même.
comme arial.ttf

EN
You must use a general font for three systems.
Linux/GNU , MacOS, Windows

You can also include the font file in the QET directory.
Other drawing programs do the same.
like arial.ttf

vadoola utilise arial dans son dxf2elmt

Pour Linux/GNU Debian, vous pouvez ajouter le fichier de police windows.
Vous devez ajouter contrib à votre /etc/apt sources.list et vous verrez ttf-mscorefonts-installer 3.8.1
et installé dans /usr/share/fonts/truetype/msttcorefonts/

Pour Linux/GNU Ubuntu

For Linux/GNU Debian can you add the windows font file.
You must add contrib in your /etc/apt sources.list and you see ttf-mscorefonts-installer 3.8.1

EDIT:

elevatormind already included the fonts in his "liberation-fonts"-Branch and I added a patch for setting default-font to "Liberation Sans" here. See above

But to repeat the reasons, why delivering a few fonts with QET is a good idea:

The user still has complete freedom to do whatever he wants!
If he wants to be compatible with different systems, it is suggested to use the fonts that QET provides.
If he wants to use other fonts, he can and may of course continue to do so!
He just needs to be aware that the particular font he has selected may not be available on other systems. This may even be the case if he re-installs his operating system.
That's why we supply a few fonts that can be used in addition to the fonts already available in the system!

Hmm, I'll have to modify my packaging scripts... . we'll see when I'm in better health.. it can take some time for me to adapt them...!
