Functions |
Etk_Object * | etk_object_new (Etk_Type *object_type, const char *first_property,...) |
| Creates a new object: it calls the corresponding constructors (from the constructor of the base class to the constructor of the more derived class) and then sets the values of the given properties.
|
Etk_Object * | etk_object_new_valist (Etk_Type *object_type, const char *first_property, va_list args) |
| Creates a new object: it calls the corresponding constructors (from the constructor of the base class to the constructor of the more derived class) and then sets the values of the given properties.
|
void | etk_object_destroy (Etk_Object *object) |
| Destroys the object: it first sets the weak-pointers to NULL, emits the "destroyed" signal, and then queues the object in the list of objects to free. Thus, the destructors will only be called at the beginning of the next main loop iteration (from the destructor of the more derived class to the destructor of the ultimate base class).
|
void | etk_object_name_set (Etk_Object *object, const char *name) |
| Sets the name of the object. The object can then be retrieved from his name with etk_object_name_find().
|
const char * | etk_object_name_get (Etk_Object *object) |
| Gets the name of the object.
|
Etk_Object * | etk_object_name_find (const char *name) |
| Finds the object called name.
|
Etk_Object * | etk_object_check_cast (Etk_Object *object, Etk_Type *type) |
| Checks if object can be cast to type. If object doesn't inherit from type, a warning is displayed in the console but the object is returned anyway.
|
Etk_Type * | etk_object_object_type_get (Etk_Object *object) |
| Gets the type of the object.
|
void | etk_object_weak_pointer_add (Etk_Object *object, void **pointer_location) |
| Adds a weak-pointer to the object. A weak-pointer is a pointer that will be automatically set to NULL when the object is destroyed.
|
void | etk_object_weak_pointer_remove (Etk_Object *object, void **pointer_location) |
| Removes a weak-pointer from the object.
|
void | etk_object_data_set (Etk_Object *object, const char *key, void *value) |
| Associates a data pointer to a key. The pointer will be carried by the object and could be retrieved later with etk_object_data_get(). If the object already has an association for the given key, the old data will be destroyed.
|
void | etk_object_data_set_full (Etk_Object *object, const char *key, void *value, void(*free_cb)(void *data)) |
| Associates a data pointer to a key. The pointer will be carried by the object and could be retrieved later with etk_object_data_get(). If the object already has an association for the given key, the old data will be destroyed.
|
void * | etk_object_data_get (Etk_Object *object, const char *key) |
| Gets the pointer associated to the given key.
|
void | etk_object_property_reset (Etk_Object *object, const char *property_name) |
| Resets the default value of a property.
|
void | etk_object_properties_set (Etk_Object *object, const char *first_property,...) |
| Sets the values of several properties.
|
void | etk_object_properties_set_valist (Etk_Object *object, const char *first_property, va_list args) |
| Sets the values of several properties.
|
void | etk_object_properties_get (Etk_Object *object, const char *first_property,...) |
| Gets the values of several properties.
|
void | etk_object_properties_get_valist (Etk_Object *object, const char *first_property, va_list args) |
| Gets the values of several properties.
|
void | etk_object_notify (Etk_Object *object, const char *property_name) |
| Calls the object's notification callbacks associated the given property. It should be called each time the value of a property is changed.
|
void | etk_object_notification_callback_add (Etk_Object *object, const char *property_name, void(*callback)(Etk_Object *object, const char *property_name, void *data), void *data) |
| Adds a notification callback associated to a property of the object. The callback will be called each time the value of the property is changed (i.e. each time etk_object_notify(object, property_name) is called).
|
void | etk_object_notification_callback_remove (Etk_Object *object, const char *property_name, void(*callback)(Etk_Object *object, const char *property_name, void *data)) |
| Removes a notification callback associated to a property of the object.
|
Variables |
int | ETK_OBJECT_DESTROYED_SIGNAL |
| Symbols for signals.
