python gtk dark theme icon buttons

After changing the theme on my Cinnamon Desktop to a dark theme (Adwaita-dark) a program that I wrote a while ago now displays the buttons incorrect. While e.g. in other programs like the file manager the color of the icons is now white they stay dark here.

Button is dark mode but icon is light mode

I created those buttons using Gtk.Button.new_from_icon_name():

import gi
gi.require_version("Gtk", "3.0")
from gi.repository import Gtk

...

button = Gtk.Button.new_from_icon_name("document-new", 1)

Is there a way of making them automatically adapt their color to the currently active theme?

Solution

  • I had the same issue and I ended up using a *-symbolic version of the icon. According to Gnome docs

    In the GNOME 3 designs we have identified a number of places where using a symbolic variant of a standard icon is desirable. Symbolic icons are usually low color or monochrome and intended to match the foreground font color. They may be used where a high color, detailed representation isn't warranted.

    It means you would rather be using

    button = Gtk.Button.new_from_icon_name("document-new-symbolic", 1)
