This class is used when you want to create panels that display content from specific Android Activity classes. Unlike IntentPanelSettings which uses Intents, this directly references Activity classes, making it more suitable for internal activities within your application where you have direct class references. Activity-based panels are very powerful and can be used to build very complex UIs but are less performant than view-based panels.

Use this when:

You're launching activities within your own app and have direct class access

You don't need to pass information to the launched activity

Signature

class ActivityPanelRegistration(val registrationId: Int, classIdCreator: (entity: Entity) -> Class<*>?, settingsCreator: (entity: Entity) -> PanelSettings, panelSetup: (PanelSceneObject, Entity) -> Unit = { _, _ -> }) : PanelRegistration

Constructors

ActivityPanelRegistration ( registrationId , classIdCreator , settingsCreator , panelSetup )

Signature

constructor(registrationId: Int, classIdCreator: (entity: Entity) -> Class<*>?, settingsCreator: (entity: Entity) -> PanelSettings, panelSetup: (PanelSceneObject, Entity) -> Unit = { _, _ -> })

Parameters

                                                    registrationId:
Int
            

Unique identifier for this panel registration

                                                    classIdCreator:
Function1
            

Function that returns the Activity class for each panel instance, allowing dynamic Activity selection based on the entity. Can return null if no activity should be launched for a particular entity.

                                                    settingsCreator:
Function1
            

Function that creates PanelSettings for each panel instance, allowing dynamic panel configuration (size, position, etc.)

                                                    panelSetup:
Function2
            

Optional setup function called after panel creation for additional configuration of the PanelSceneObject

Returns

ActivityPanelRegistration

Properties

activityClass : Class? [Get][Set]	Activity class if the panel is powered by an activity and its layout/logic. Signature var activityClass: Class<*>?
init : Function2 [Get]	The initialization block that will be called when the panel is created Signature val init: PanelRegistration.(entity: Entity) -> Unit
layoutResourceId : Int? [Get][Set]	Layout resource id if the panel is view-based and created in the same immersive activity. Signature var layoutResourceId: Int?
panelIntent : Intent? [Get][Set]	Intent to launch the panel's activity if the panel is activity-based. Signature var panelIntent: Intent
registrationId : Int [Get]	The unique identifier for this panel Signature val registrationId: Int

Functions

config ( overriding , block )	Signature fun config(overriding: Boolean = true, block: PanelConfigOptions.() -> Unit): PanelRegistration Parameters overriding: Boolean block: Function1 Returns PanelRegistration
panel ( overriding , block )	Signature fun panel(overriding: Boolean = true, block: PanelSceneObject.() -> Unit): PanelRegistration Parameters overriding: Boolean block: Function1 Returns PanelRegistration
panelComponent ()	Returns the Panel component that will be used to create the panel entity. Signature fun panelComponent(): Panel Returns Panel
panelCreator ( scene , spatialContext )	Returns a function that takes an entity as input and returns a PanelSceneObject. This function will be used to create the panel scene object in PanelCreationSystem. Whenever you create Entity with Panel(registrationId) component, this function will be called to create the panel scene object. Signature open override fun panelCreator(scene: Scene, spatialContext: SpatialContext): (entity: Entity) -> PanelSceneObject Parameters scene: Scene The scene in which the panel will be created. spatialContext: SpatialContext The spatial context of the panel. Returns Function1 A function that takes an entity as input and returns a PanelSceneObject.
view ( block )	Parameters block: Function1 Returns PanelRegistration
