APIs

RemoteWindow(target: WindowAnimationTarget)

Creates a <RemoteWindow> through a window animation object.

Parameters

Name	Type	Mandatory	Description
target	WindowAnimationTarget	Yes	Description of the animation window to control.

WindowAnimationTarget

Implements a target window, which is used to remotely control the animation.

Name	Type	Description
bundleName	string	Process corresponding to the animation window.
abilityName	string	Ability corresponding to the animation window.
windowBounds	RRect	Actual size of the animation window.
missionId	number	Mission ID.

RRect

Implements a rounded rectangle.

Name	Type	Description
left	number	Horizontal coordinate of the upper left corner of the animation window relative to the screen.
top	number	Vertical coordinate of the upper left corner of the animation window relative to the screen.
width	number	Width of the animation window.
height	number	Height of the animation window.
radius	number	Radius of the rounded corner of the animation window.

Attributes

The universal attributes are supported.

Events

The universal events are supported.

Example

The <RemoteWindow> component needs to receive the WindowAnimationTarget object passed from the WindowAnimationController object set through windowAnimationManager. You can create a RemoteWindowExample.ets file and encapsulate the RemoteWindowExample component and the passed WindowAnimationTarget object. The <RemoteWindow> component can be used only in the system application Launcher. Therefore, you can place the RemoteWindowExample component in the build function of the EntryView.ets page of Launcher, compile Launcher, and push the Launcher installation package to the device system.
