ContentSlot

The ContentSlot component is a component designed to render and manage components created on the native layer using C APIs.

With support for hybrid development, the ContentSlot component is recommended when the container is an ArkTS component and the child component is created on the native side.

NOTE

The initial APIs of this module are supported since API version 12. Newly added APIs will be marked with a superscript to indicate their earliest API version.

import { NodeContent } from '@kit.ArkUI'

@Entry
@Component
struct Parent {
    private nodeContent: Content = new NodeContent();

    aboutToAppear() {
        // Create a node through the C API and add it to the nodeContent manager.
        nativeNode.createNativeNode(this.nodeContent);
    }

    build() {
        Column() {
            // Display the native components stored in the nodeContent manager.
            ContentSlot(this.nodeContent)
        }
    }
}
