In Zepp OS, API_LEVEL 4.0 introduces support for Flex layout, allowing developers to build smartwatch application interfaces in a way similar to Web development, greatly improving layout flexibility and development efficiency.

Widget Property Read/Write​

For more details, refer to Widget Getter/Setter Feature.

Starting from API_LEVEL 4.0, Zepp OS supports direct access and modification of widget properties through getter/setter features, making property read/write operations more concise and intuitive.

The widget documentation will indicate property access support status.

import { createWidget, widget, prop } from '@zos/ui'

Page({
  build() {
    // Create TEXT widget
    const textWidget = createWidget(widget.TEXT, {
      // ...
    })

    // Using getter to read properties
    console.log('Text content:', textWidget.text)
    console.log('Text color:', textWidget.color)
    console.log('Text position:', textWidget.x, textWidget.y)

    // Using setter to set properties
    textWidget.text = 'Updated Text'
    textWidget.color = 0xff0000
    textWidget.x = 120

    // Comparison with old method
    // Reading properties
    const oldText = textWidget.getProperty(prop.TEXT)
    console.log('Old way - Text content:', oldText)

    // Setting properties
    textWidget.setProperty(prop.TEXT, 'Set by old method')
    textWidget.setProperty(prop.MORE, {
      color: 0x00ff00,
      x: 150
