This example demonstrates how to change the mouse cursor style using setCursor.

NOTE

To avoid confusion with cursorControl instances, it is recommended that you obtain a UIContext instance using the getUIContext API, and then obtain the cursorControl instance bound to the context through the getCursorController API.

// xxx.ets
import { pointer } from '@kit.InputKit';

@Entry
@Component
struct CursorControlExample {
  @State text: string = ''
  controller: TextInputController = new TextInputController()

  build() {
    Column() {
      Row().height(200).width(200).backgroundColor(Color.Green).position({x: 150 ,y:70})
        .onHover((flag) => {
          if (flag) {
            // You are advised to use this.getUIContext().getCursorController().setCursor().
            cursorControl.setCursor(pointer.PointerStyle.EAST)
          } else {
            // You are advised to use this.getUIContext().getCursorController().restoreDefault().
            cursorControl.restoreDefault()
          }
        })
      Row().height(200).width(200).backgroundColor(Color.Blue).position({x: 220 ,y:120})
        .onHover((flag) => {
          if (flag) {
            // You are advised to use this.getUIContext().getCursorController().setCursor().
            cursorControl.setCursor(pointer.PointerStyle.WEST)
          } else {
            // You are advised to use this.getUIContext().getCursorController().restoreDefault().
            cursorControl.restoreDefault()
          }
        })
    }.width('100%')
  }
}

Diagram:

When the mouse pointer is placed over the blue area, the west arrow cursor is displayed.
