Interface

GcrCollection

Description [src] 

interface Gcr.Collection : GObject.Object

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.

Prerequisite

In order to implement Collection, your type must inherit from GObject.

Implementations

Instance methods

gcr_collection_contains

Check whether the collection contains an object or not.

gcr_collection_emit_added

gcr_collection_get_length

Get the number of objects in this collection.

gcr_collection_get_objects
