With version 3.0, GnuCash has upgraded to the GTK3 library from GTK2.

Customization

As noted in bug 791823, there is no GTK theming tool available for GTK3 on Windows. However, this is relatively easy to resolve manually by using a CSS file and placing it at the correct location.

The comprehensive GTK+ CSS Overview is available at Gnome Developer web site.

Sample GnuCash CSS file:

• GTK 3 CSS

For extra info, you can also look at these low-level customizations:

• gnucash-310
• gnucash-320

Note that these contain the variables, as explained in the CSS customization overview, under Colors section.

To locate the UI elements for customization, you can use the GTK Inspector tool.

To customize the GnuCash theme, create and/or modify the Cascading Style Sheets (CSS) file. The location of this file is explained in the following entry: Where can I find the GTK resource file? Note that, by default, no gtk-3.0.css file will be created so you have to create one manually. Then add the CSS rules or copy values from an existing theme. There are plenty of GTK3 theme resources caused by the fact that CSS is a widely-adopted standard for UI styling and many people are familiar with it.

Some GTK3 theme resource sites:

• Gnome Look
• Devian Art

etc.

Dark Theme

Here is an example of a dark theme for GnuCash 3. Note that this is still a work in progress, though.

• Black Theme

Due to the lack of a dark theme on Windows, the guide would be the Adwaita Dark custom theme.
