Known Implementations
GcrCollection is implemented by GcrFilterCollection, GcrSimpleCollection and GcrUnionCollection.
Description
A GcrCollection is used to group a set of objects. This is an abstract interface which can be used to determine which objects show up in a selector or other user interface element.
Use gcr_simple_collection_new() to create a concrete implementation of this
interface which you can add objects to.
Functions
gcr_collection_get_length ()
guint
gcr_collection_get_length (GcrCollection *self);
Get the number of objects in this collection.
gcr_collection_get_objects ()
GList *
gcr_collection_get_objects (GcrCollection *self);
Get a list of the objects in this collection.
gcr_collection_contains ()
gboolean gcr_collection_contains (GcrCollection *self,GObject *object);
Check whether the collection contains an object or not.
gcr_collection_emit_added ()
void gcr_collection_emit_added (GcrCollection *self,GObject *object);
Emit the “added” signal for the given object. This function is used by implementors of this interface.
gcr_collection_emit_removed ()
void gcr_collection_emit_removed (GcrCollection *self,GObject *object);
Emit the “removed” signal for the given object. This function is used by implementors of this interface.
Types and Values
GcrCollection
typedef struct _GcrCollection GcrCollection;
