===== Events =====

==== Inherited ====

^ [[:develop:api:efl:object|Efl.Object]] ^^^
|  | **[[:develop:api:efl:object:event:del|del]]** | %%Object is being deleted. See %%[[:develop:api:efl:object:method:destructor|Efl.Object.destructor]]%%.%% |
|  | **[[:develop:api:efl:object:event:destruct|destruct]]** | %%Object has been fully destroyed. It can not be used beyond this point. This event should only serve to clean up any reference you keep to the object.%% |

|  | **[[:develop:api:efl:object:event:noref|noref]]** | %%Object has lost its last reference, only parent relationship is keeping it alive. Advanced usage.%% |
|  | **[[:develop:api:efl:object:event:ownership_shared|ownership,shared]]** | %%Object has acquired a second reference. It has multiple owners now. Triggered whenever increasing the refcount from one to two, it will not trigger by further increasing the refcount beyond two.%% |
|  | **[[:develop:api:efl:object:event:ownership_unique|ownership,unique]]** | %%Object has lost a reference and only one is left. It has just one owner now. Triggered whenever the refcount goes from two to one.%% |
^ [[:develop:api:efl:ui:radio_group|Efl.Ui.Radio_Group]] ^^^
|  | **[[:develop:api:efl:ui:radio_group:event:value_changed|value,changed]]** | %%Emitted each time the %%''selected_value''%% changes. The event information contains the %%[[:develop:api:efl:ui:radio:property:state_value|Efl.Ui.Radio.state_value]]%% of the newly selected button or -1 if no button is now selected.%% |
^ [[:develop:api:efl:ui:single_selectable|Efl.Ui.Single_Selectable]] ^^^
|  | **[[:develop:api:efl:ui:single_selectable:event:selection_changed|selection_changed]]** | %%Emitted when there is a change in the selection state. This event will collect all the item selection change events that are happening within one loop iteration. This means, you will only get this event once, even if a lot of items have changed.
