Answer 1

gtk_widget_override_background_color()

This the GTK 3.x+ way (until GTK 3.16). From

https://developer.gnome.org/gtk3/unstable/GtkWidget.html#gtk-widget-modify-base

" gtk_widget_modify_base has been deprecated since version 3.0 and should not be used in newly-written code. Use gtk_widget_override_background_color() instead"

UPDATE: thegtknerd notes that this method too is now deprecated and it has been since 3.16.

Answer 3

As of gtk3, I believe the proper way to do that is through CSS. Register a gtk style sheet though GtkCssProvider , then you can write this CSS:

textview text {
  background-color: @theme_bg_color;
}

We can see the relevant CSS nodes in the documentation for GtkTextView. In this case I put @theme_bg_color which is an adwaita CSS variable , but you can as well put anything that goes in a usual CSS file, like red or #ff0000 .
