CssProviderRef

public struct CssProviderRef : CssProviderProtocol, GWeakCapturing

GtkCssProvider is an object implementing the GtkStyleProvider interface. 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_screen().

In addition, certain files will be read when GTK+ is initialized. First, the file $XDG_CONFIG_HOME/gtk-3.0/gtk.css is loaded if it exists. Then, GTK+ loads the first existing file among XDG_DATA_HOME/themes/THEME/gtk-VERSION/gtk.css, $HOME/.themes/THEME/gtk-VERSION/gtk.css, $XDG_DATA_DIRS/themes/THEME/gtk-VERSION/gtk.css and DATADIR/share/themes/THEME/gtk-VERSION/gtk.css, where THEME is the name of the current theme (see the GtkSettings:gtk-theme-name 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 3.0.

In the same way, GTK+ tries to load a gtk-keys.css file for the current key theme, as defined by GtkSettings:gtk-key-theme-name.

The CssProviderRef type acts as a lightweight Swift reference to an underlying GtkCssProvider instance. It exposes methods that can operate on this data type through CssProviderProtocol conformance. Use CssProviderRef only as an unowned reference to an existing GtkCssProvider instance.
