With version 3.0, GnuCash has adopted GTK3 library.

Customization

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

Overview of CSS customization of GTK3: https://developer.gnome.org/gtk3/stable/chap-css-overview.html

Sample GnuCash CSS files:

- https://github.com/Gnucash/gnucash/blob/master/gnucash/gnucash-310.css

- https://github.com/Gnucash/gnucash/blob/master/gnucash/gnucash-320.css

To locate the UI elements for customization, you can use the GTK Inspector tool: https://wiki.gnome.org/Projects/GTK%2B/Inspector

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: https://wiki.gnucash.org/wiki/FAQ#Q:_Where_can_I_find_the_gtk_resource_file.3F 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:

etc.
