StyleProviderProtocol

public protocol StyleProviderProtocol

GtkStyleProvider is an interface for style information used by GtkStyleContext.

See [methodGtk.StyleContext.add_provider] and [funcGtk.StyleContext.add_provider_for_display] for adding GtkStyleProviders.

GTK uses the GtkStyleProvider implementation for CSS in [ifaceGtk.CssProvider].

The StyleProviderProtocol protocol exposes the methods and properties of an underlying GtkStyleProvider instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see StyleProvider. Alternatively, use StyleProviderRef as a lighweight, unowned reference if you already have an instance you just want to use.
