Class
GtkCssProvider
Description [src]
final class Gtk.CssProvider : GObject.Object {
parent_instance: GObject
}GtkCssProvider is an object implementing the GtkStyleProvider interface
for CSS.
It is able to parse CSS-like input in order to style widgets.
An application can make GTK parse a specific CSS style sheet by calling
gtk_css_provider_load_from_file() or
gtk_css_provider_load_from_resource()
and adding the provider with gtk_style_context_add_provider() or
gtk_style_context_add_provider_for_display().
In addition, certain files will be read when GTK is initialized.
First, the file $XDG_CONFIG_HOME/gtk-4.0/gtk.css is loaded if it
exists. Then, GTK loads the first existing file among
XDG_DATA_HOME/themes/THEME/gtk-VERSION/gtk-VARIANT.css,
$HOME/.themes/THEME/gtk-VERSION/gtk-VARIANT.css,
$XDG_DATA_DIRS/themes/THEME/gtk-VERSION/gtk-VARIANT.css and
DATADIR/share/themes/THEME/gtk-VERSION/gtk-VARIANT.css,
where THEME is the name of the current theme (see the
GtkSettings:gtk-theme-name setting), VARIANT is the
variant to load (see the
GtkSettings:gtk-application-prefer-dark-theme setting),
DATADIR is the prefix configured when GTK was compiled (unless
overridden by the GTK_DATA_PREFIX environment variable), and
VERSION is the GTK version number. If no file is found for the
current version, GTK tries older versions all the way back to 4.0.
To track errors while loading CSS, connect to the
GtkCssProvider::parsing-error signal.
