Member Data Documentation

◆ NavigateNextMessage

MessageType<ImplicitActivityChangeRequestMessageArguments> kanzi::ExclusiveActivityHostConcept::NavigateNextMessage

static

In an Exclusive Activity Host requests the activation of the next Activity node in that Exclusive Activity Host node.

◆ NavigatePreviousMessage

MessageType<ImplicitActivityChangeRequestMessageArguments> kanzi::ExclusiveActivityHostConcept::NavigatePreviousMessage

static

In an Exclusive Activity Host requests the activation of the previous Activity node in that Exclusive Activity Host node.

◆ ExclusiveActivityHostContentProperty

PropertyType<string> kanzi::ExclusiveActivityHostConcept::ExclusiveActivityHostContentProperty

static

Describes the content of an Exclusive Activity Host node.

An Exclusive Activity Host node uses the value of this property to instantiate Activity node prefabs and to control the status and lifetime of its child Activity nodes.

Kanzi Studio user cannot directly edit this property. The ActivityBrowserController sets the value of this property according to the changes done to the state of the Activity Tree in the ActivityBrowser.

The expected format for the property value is the name of an Activity node that an ExclusiveActivityHost initially activates, followed by a list of Activity node descriptions. Each of this Activity node descriptions contains:

The name of the Activity node
ControllerProperty reference value of the Activity node
Path to the prefab of that Activity node The values in this property must be separated by a comma.

Syntax: {<is-initially-active-activity-name>,{<child-activity-name>,<controller-property-value>,<activity-prefab-path>},{<child-activity-name>,<controller-property-value>,<activity-prefab-path>},...} Example: {name0,{name1,666,path1},{name2,123,path2}}.

By default the value of this property is empty, that is, the Activity Host does not contain any content.

Since: Kanzi 3.9.0

◆ ActiveActivityProperty

PropertyType<string> kanzi::ExclusiveActivityHostConcept::ActiveActivityProperty

static

The name of the child Activity node of an Exclusive Activity Host, that is either in ActivityConcept::Status::Active or in ActivityConcept::Status::Activating state.

By default this property does not point to any Activity node. The default value is "".

◆ ActivationPathProperty

PropertyType<string> kanzi::ExclusiveActivityHostConcept::ActivationPathProperty

static

The activation path containing the branch of the Activity tree that is requested to be activated.

It stores the path value only from the moment of receiving an activation request with an activation path longer than just one node, to when this path is forwarded to the first element in the activation path, then The property is reset to default. By default, this property does not contain any activation path. You should not update this property. The Exclusive Activity Host does not react to a change on this property. Kanzi uses this property internally, together with ActiveActivityProperty, during activation with ActivityHostConcept::ActivateActivityMessage.

Since: Kanzi 3.9.0

◆ FocusOnActivatingActivityProperty

PropertyType<ExclusiveActivityHostFocusingPolicy> kanzi::ExclusiveActivityHostConcept::FocusOnActivatingActivityProperty

static

Sets the policy that an Exclusive Activity Host uses to decide whether it tries to set focus to an activating Activity.

See also: ExclusiveActivityHostConcept::ExclusiveActivityHostFocusingPolicy.

Since: Kanzi 3.9.4
