CssProviderRef

public struct CssProviderRef : CssProviderProtocol, GWeakCapturing

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 [methodGtk.CssProvider.load_from_file] or [methodGtk.CssProvider.load_from_resource] and adding the provider with [methodGtk.StyleContext.add_provider] or [funcGtk.StyleContext.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 [propertyGtk.Settings:gtk-theme-name] setting), VARIANT is the variant to load (see the [propertyGtk.Settings: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 [signalGtk.CssProvider::parsing-error] signal.

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.

    Untyped pointer to the underlying `GtkCssProvider` instance.
