Why do the isStatusBarLightIcon and isNavigationBarLightIcon attributes not take effect when window.setSystemBarProperties() is called?

Applicable to: OpenHarmony SDK 3.2.5.3, stage model of API version 9

In effect, the isStatusBarLightIcon and isNavigationBarLightIcon attributes turn the font white when set to true. If statusBarContentColor is also set in window.setSystemBarProperties(), the isStatusBarLightIcon attribute does not take effect. Similarly, if navigationBarContentColor is set, the isNavigationBarLightIcon attribute does not take effect.

How do I hide the status bar to get the immersive effect?

Applicable to: OpenHarmony SDK 3.2.6.3, stage model of API version 9

  1. Use the onWindowStageCreate to obtain a windowClass object.

    onWindowStageCreate(windowStage) {
  // When the main window is created, set the main page for this ability.
  console.log("[Demo] EntryAbility onWindowStageCreate")
  windowStage.getMainWindow((err, data) => {
    if (err.code) {
      console.error('Failed to obtain the main window.')
      return;
    }
    // Obtain a windowClass object.
    globalThis.windowClass = data; 
  })
}

  2. Enable the full-screen mode for the window and hide the status bar.

     globalThis.windowClass.setFullScreen(isFullScreen, (err, data) => {
  if (err.code) {
    console.error('Failed to enable the full-screen mode. Cause:' + JSON.stringify(err));
    return;
  }
    console.info('Succeeded in enabling the full-screen mode. Data: ' + JSON.stringify(data));
  });

How do I obtain the window width and height?

Applicable to: OpenHarmony SDK 3.2.3.5, stage model of API version 9

Use window.getProperties() to obtain the window properties. The windowRect field in the properties specifies the window width and height.

let promise = windowClass.getProperties();
promise.then((data)=> {
  console.info('Succeeded in obtaining the window properties. Data: ' + JSON.stringify(data.windowRect));
}).catch((err)=>{
  console.error('Failed to obtain the window properties. Cause: ' + JSON.stringify(err));
});
