Member Enumeration Documentation

◆ Status

enum kanzi::ActivityConcept::Status

strong

Defines possible states of an Activity.

Activity Host nodes can activate and deactivate their child Activities. This enumeration defines the possible states of an Activity during the the process of activation and deactivation. You can use this functionality to react to changes in Activity status in your application code and in Kanzi Studio.

See also: Activity, StatusProperty

Enumerator
Active	The Activity is active. In an Exclusive Activity Host only one child Activity can be in the Active state at a time. In a Parallel Activity Host more than one Activity can be in the Active state at the same time, therefore any Activity can be in any state.
Inactive	The Activity is inactive. Inactive Activities do not show their content.
Activating	The Activity is transitioning into the active state. In an Exclusive Activity Host while one Activity is in Activating state, another Activity can be in the Deactivating state at the same time. In a Parallel Activity Host more than one Activity can be in the Active state at the same time, therefore any Activity can be in any state.
Deactivating	The Activity is transitioning into the inactive state. In an Exclusive Activity Host while one Activity is in Deactivating state, another Activity can at the same time be in the Activating state. In a Parallel Activity Host more than one Activity can be in the Active state at the same time, therefore any Activity can be in any state.

NodeWeakPtr kanzi::ActivityConcept::s_activationTargetActivity

static

The Activity that is the activation target.

Kanzi waits for descendant Activities to activate until the last-focused node of the activating Activity tree finishes loading. After that Kanzi applies the focusing policy of the activation target. The activation target is the Activity that the application logic specifically requests to be activated. Any other Activities that Kanzi activates as a side effect are not activation target Activities and Kanzi does not consider their focusing policy this time.
