WindowBase - API / NativeScript

Cross-platform base for any window surface.

Carries identity, role, state, lifecycle events and the native accessors. Surfaces that host a NativeScript view tree are NativeWindow instances.

Constructors

Constructor

new WindowBase(): WindowBase;

Returns

WindowBase

Inherited from

Observable.constructor

Properties

android?

readonly optional android?: {
  activity: AppCompatActivity;
};

Defined in: native-window/index.d.ts:71

The Android surface backing this window, or undefined when not running on Android or when the activity is already gone.

activity

readonly activity: AppCompatActivity;

id

readonly id: string;

Defined in: native-window/index.d.ts:41

Stable identifier of this window, unique for the lifetime of the JS context. Survives a detach/re-attach, so it can be used to correlate a window across an iOS scene reconnect or an Android activity recreation.

ios?

readonly optional ios?: {
  scene?: UIWindowScene;
  uiWindow: UIWindow;
};

Defined in: native-window/index.d.ts:65

The iOS surface backing this window, or undefined when not running on iOS. scene is absent for apps still on the pre-scene (window-only) lifecycle.

scene?

readonly optional scene?: UIWindowScene;

uiWindow

readonly uiWindow: UIWindow;

isPrimary

readonly isPrimary: boolean;

Defined in: native-window/index.d.ts:59

Whether this is the application's primary window.

At most one window is primary at a time. When the primary window closes another attached window is promoted and primaryWindowChanged is raised on the Application.

role

readonly role: WindowRole;

Defined in: native-window/index.d.ts:46

The purpose this window surface serves.

state

readonly state: WindowState;

Defined in: native-window/index.d.ts:51

Where this window currently sits in its lifecycle.

propertyChangeEvent

static propertyChangeEvent: string;

Defined in: data/observable/index.ts

String value used when hooking to propertyChange event.

Ns Event

propertyChange

Inherited from

Observable.propertyChangeEvent

Methods

_createPropertyChangeData()

_createPropertyChangeData(
   propertyName: string, 
   value: any, 
   oldValue?: any): PropertyChangeData;

Defined in: data/observable/index.ts

This method is intended to be overriden by inheritors to provide additional implementation.

Parameters

Parameter	Type
`propertyName`	`string`
`value`	`any`
`oldValue?`	`any`

Returns

PropertyChangeData

Inherited from

Observable._createPropertyChangeData

Parameters

Parameter	Type

addEventListener(
   eventName: string, 
   callback: (data: EventData) => void, 
   thisArg?: any, 
   once?: boolean): void;

Defined in: data/observable/index.ts

Adds a listener for the specified event name.

Parameters

Parameter	Type	Description
`eventName`	`string`	Name of the event to attach to.
`callback`	(`data`: `EventData`) => `void`	A function to be called when some of the specified event(s) is raised.
`thisArg?`	`any`	An optional parameter which when set will be used as "this" in callback method call.

Ends the window session: the native surface is dismissed, close is raised and the window is dropped from the Application registry.

Returns

void

get(name: string): any;

Defined in: data/observable/index.ts

Gets the value of the specified property.

Parameters

Parameter	Type
`name`	`string`

Returns

any

Inherited from

Type Parameters

Type Parameter
`T` extends `Optional`<`EventData`, `"object"`>

Parameters

Parameter	Type	Description
`data`	`T`	an object that satisfies the EventData interface, though with an optional 'object' property. If left undefined, the 'object' property will implicitly be set as this Observable instance.

   callback: (data: WindowBaseEventData) => void, 
   thisArg?: any): void;

Defined in: native-window/index.d.ts:99

Raised when the window enters the foreground.

Overrides

Observable.on

Call Signature

on(
   event: "attached", 
   callback: (data: WindowBaseEventData) => void, 
   thisArg?: any): void;

Defined in: native-window/index.d.ts:105

Raised when a native surface is bound to the window - both on the first connect and on every re-attach after a detached.

Parameters

Parameter	Type
`event`	`"attached"`
`callback`	(`data`: `WindowBaseEventData`) => `void`
`thisArg?`	`any`

Returns

void

Overrides

Observable.on

Call Signature

on(
   event: "detached", 
   callback: (data: WindowBaseEventData) => void, 
   thisArg?: any): void;

Defined in: native-window/index.d.ts:115

Raised when the native surface goes away while the window session stays alive (iOS scene disconnect, Android activity recreation).

The window stays registered on the Application and keeps its listeners, so the same instance is handed back when a surface re-attaches and handlers registered before the detach keep working afterwards.

Parameters

Parameter	Type
`event`	`"detached"`
`callback`	(`data`: `WindowBaseEventData`) => `void`
`thisArg?`	`any`

Returns

void

Overrides

Observable.on

Call Signature

on(
   event: "close", 
   callback: (data: WindowBaseEventData) => void, 
   thisArg?: any): void;

Defined in: native-window/index.d.ts:125

Raised when the window session ends for good.

Fires exactly once per window. Listeners stay registered for the whole teardown, so a handler added at any earlier point still observes it; immediately after it is dispatched the framework drops every listener on the instance, so nothing registered on a window outlives the window.

Parameters

Parameter	Type
`event`	`"close"`
`callback`	(`data`: `WindowBaseEventData`) => `void`
`thisArg?`	`any`

Returns

void
