This class is used when you want to create panels with Views that are generated programmatically at runtime rather than from static layout resources. View-based panels are more performant than Activity-based panels.

Use this when:

You want to dynamically construct a View-based UIs based on data or other runtime conditions

You want to quickly prototype a UI idea

Constructors

ViewPanelRegistration ( registrationId , dynamicViewCreator , settingsCreator , panelSetupWithRootView )

Parameters

registrationId: Int Unique identifier for this panel registration

dynamicViewCreator: Function2 Function that creates a View for each panel instance, receiving both the entity and Android context for maximum flexibility in View creation

settingsCreator: Function1 Function that creates PanelSettings for each panel instance, allowing dynamic panel configuration (size, position, etc.)

panelSetupWithRootView: Function3 Optional setup function called after panel creation with access to the created root View, PanelSceneObject, and Entity for additional configuration

Returns

ViewPanelRegistration

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

Methods

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`
