General Fontsize

[matz3ibm]

ZKN3 became essential for my work and is one of my favourite applications - highly appreciate also the stability.

Regarding fontsize, latest desktop environments and higher resolutions, would it be possible to add a global scaling factor or percentage to increase all fontsizes together in the ZKN settings? And, in case, a similar sizing option for graphical buttons, too?

I have a 4K laptop (ThinkPad T15g Gen2i) running Linux (the following does unfortunately not apply to Windows 11, I've tested it) and had a hard time setting all of the fontsizes in a practical manner. But now I've found what might be what you're looking for, my startup command for ZKN3 looks like this:

java -Dsun.java2d.uiScale=2 -jar /opt/ZKN3/Zettelkasten-3.2022.8.jar

The -Dsun.java2d.uiScale=2 option yields a fantastic look of the application, I'm extremely happy with this! You may change the factor of 2 until the look is right and meets your needs.
Let me know if this is a solution for you, too, I'd really like to hear from you.
All the best!

PS: Although I've done quite an amount of research to find a Windows solution to the problem, I wasn't successful. Any hint to a solution is appreciated, thx!

Thanks a lot! - Just tried on a Windows 10 21H, Java 1.8 with a Thinkpad P15 - and as you mentioned, it doesn't work. What works is modifying the java.exe properties:

1. locate your java.exe > where java
2. Right click -> Properties
3. Go to Compatibility tab
4. Check Override high DPI scaling behavior and
   Choose System for Scaling performed by: Application
5. In case repeat for any of the found java.exe instances

and

But even after changing all java.exes' I have to execute ZKN via .bat file and put in the -Dsun.java2d.uiScale=2 Parameter...

Would be nice to get this fixed via the "Einstellungen / Settings" tab and/or with a general parameter for Windows as well as for Linux
