Enlarge NetLogo (menus, fonts) to fit high screen resolution

Question

for NetLogo 5.3.1 on linux/Gnome: my screen has a 2550 * 1440 resolution and makes NetLogo almost unreadable. I know that during a running session, I can increase the font size in the editor. But where can I configure NetLogo to always start with a larger font size? The menu icons and fonts are tiny. Any way to configure NetLogo to make them larger? Thank you very much!

Answer 1

The JEP 263: HiDPI Graphics on Windows and Linux defines the appropiate behaviour of the OpenJDK for HiDPI, it's implemented in OpenJdk 9 so:

• Install OpenJdk 9

• Open NetLogo.cfg (mine is at /opt/netlogo/app/NetLogo.cfg)

  • To find it use in shell:

    whereis NetLogo ls -l /usr/bin/NetLogo ls -l /opt/netlogo/app

• Add at the [JVMOptions] section -Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel -Dawt.useSystemAAFontSettings=on -Dsun.java2d.dpiaware=true

To use the GTK L&F that is prepared to HiDPI, then you can use the GNOME Tweak Tool to balance the font size.

With OpenJDK >= 9, the UI can be scaled via an environment variable:

bash -c 'export GDK_SCALE=2 && java -jar /PATH_OF_NETLOGO/app/netlogo-6.2.0.jar' &
