Windows AIO themes
The Gramps theme on the Windows AIO(All in one) installation can be changed so long as the Gramps AIO is version 5.0.x or newer and uses Gtk 3.18 to 3.24 you can select a theme that MUST support those versions (also themes that are designed for a later version may not work).
GTK Themes can be found in the GTK3/4 Themes section on gnome-look.org that provide Eyecandy for your GTK Desktop.
Example theme installation
For this example the MacTahoe-gtk-theme (By vinceliuice) provides a good looking dark theme.
- Start by download the file of latest release from https://github.com/vinceliuice/MacTahoe-gtk-theme/releases
- After downloading the theme file (often a tar.gz or a .zip ) decompress it using 7-zip of similar. In this example the filename was MacTahoe-gtk-theme-2025-08-22.zip
The decompressed files should be stored in "C:\Users\you\.themes" (replacing 'you' with your user name) so that the final directory structure looks like:
C:\Users\you\.themes
Ollis-Gtk-3.18-Dark-Grad
Gtk-2.0
Gtk-3.0
...
Find your AIO installation and edit the file in "C:\GrampsAIO64-4.2.6\etc\gtk-3.0\settings.ini".
Add in a line that says "gtk-theme-name = Ollis-Gtk-3.18-Dark-Grad" (or whatever your theme name is). The complete file should look like this:
[Settings] gtk-theme-name = Ollis-Gtk-3.18-Dark-Grad gtk-xft-antialias=1 gtk-xft-hinting=1 gtk-xft-hintstyle=hintfull gtk-xft-rgba=rgb

Note: When you start Gramps, your console may show some "Gtk-WARNING **: Theme parsing error" messages. These are usually harmless, but if there are a lot, and your Gramps screen doesn't look right, then your theme may not be compatible with the version of Gtk Gramps AIO is using. |
You can check the Gramps Gtk version by starting Gramps from the console;
Gramps -v
Gramps Settings: ---------------- python : 3.5.2 gramps : GrampsAIO64-4.2.6 gtk++ : 3.18.9 ...
