4. Destroy the subwindow.
When the subwindow is no longer needed, you can call `destroy` to destroy it.
When the subwindow is no longer needed, you can call **destroy()** to destroy it.
```js
// Destroy the subwindow when a click event outside the window is detected.
windowClass.on('touchOutside', () => {
console.info('touch outside');
windowClass.destroy((err, data) => {
// Call destroy() to destroy the subwindow when it is no longer needed.
windowClass.destroy((err) => {
if (err.code) {
console.error('Failed to destroy the subwindow. Cause:' + JSON.stringify(err));
return;
}
console.info('Succeeded in destroying the subwindow. Data: ' + JSON.stringify(data));
});
console.info('Succeeded in destroying the subwindow.');
});

2. Implement the immersive effect. You can use any of the following methods:
- Method 1: Call `setFullScreen` to set the main window to be displayed in full screen. In this case, the navigation bar and status bar are hidden.
- Method 2: Call `setSystemBarEnable` to hide the navigation bar and status bar.
- Method 3: Call `setLayoutFullScreen` to enable the full-screen mode for the main window layout. Call `setSystemProperties` to set the opacity, background color, text color, and highlighted icon of the navigation bar and status bar to ensure that their display effect is consistent with that of the main window.
- Method 1: Call **setFullScreen** to set the main window to be displayed in full screen. In this case, the navigation bar and status bar are hidden.
- Method 2: Call **setSystemBarEnable** to hide the navigation bar and status bar.
- Method 3: Call **setLayoutFullScreen** to enable the full-screen mode for the main window layout. Call **setSystemProperties** to set the opacity, background color, text color, and highlighted icon of the navigation bar and status bar to ensure that their display effect is consistent with that of the main window.
```js
// Use method 1 to implement the immersive effect.
let isFullScreen = true;
mainWindowClass.setFullScreen(isFullScreen, (err, data) => {
mainWindowClass.setFullScreen(isFullScreen, (err) => {
if (err.code) {
console.error('Failed to enable the full-screen mode. Cause:' + JSON.stringify(err));
return;
}

3. Load content for the immersive window and show it.
Call `loadContent` and `show` to load and display the content in the immersive window.
Call **loadContent** and **show** to load and display the content in the immersive window.
```js
// Load the page content to the immersive window.
mainWindowClass.loadContent("pages/page3", (err, data) => {

if (err.code) {
console.error('Failed to load the content. Cause: ' + JSON.stringify(err));
return;
}
console.info('Succeeded in loading the content. Data: ' + JSON.stringify(data));
console.info('Succeeded in loading the content.');
// Show the immersive window.
mainWindowClass.show((err, data) => {
mainWindowClass.show((err) => {
if (err.code) {
console.error('Failed to show the window. Cause: ' + JSON.stringify(err));
return;
}
console.info('Succeeded in showing the window. Data: ' + JSON.stringify(data));
