The Stylable interface defines how objects manage styling. The stylable interface would be paired with a Style object, which contains the parsed style sheet data and performs the matching of stylables to the style sheet. The Style object would normally be a singleton and has a signal that it will emit when it changes, which the Stylable would pick up.
- Allows any GObject to become "stylable"
- Seperates the style data (including context) from the object
- Each stylable implementation will install the properties that it needs using a GParamSpec.
(For example, GtkWidget might install a "background-color" property)
- Each stylable provides implementations of the context functions:
is_a (); get_container (); get_base_style (); get_id (); get_type (); get_class (); get_pseudo_class (); get_attribute (); get_viewport ();
- These functions are used by the style object to match against the style sheet.
