GwyWatchable requires GObject.
GwyWatchable is an abstract interface for a value-like objects whose changes can be watched, i.e., they cause emission of a "value_changed" signal. You can use gwy_watchable_value_changed() to programatically emit the signal.
struct GwyWatchableClass { GTypeClass parent_class; void (*value_changed)(GObject *watchable); };
void gwy_watchable_value_changed (GObject *watchable);
Emits a "value_changed" signal on a watchable object.
