In the stage model, the main window of an application is created and maintained by a **UIAbility** instance. In the **onWindowStageCreate** callback of the **UIAbility** instance, use **WindowStage** to obtain the main window of the application and set its properties. You can also set the properties (for example, **maxWindowWidth**) in the [module.json5 file](../quick-start/module-configuration-file.md#abilities).
### How to Develop
1. Obtain the main window.
Call **getMainWindow** to obtain the main window of the application.
2. Set the properties of the main window.
You can set multiple properties of the main window, such as the background color, brightness, and whether the main window is touchable. The code snippet below uses the **touchable** property as an example.

## Experiencing the Immersive Window Feature
To create a better video watching and gaming experience, you can use the immersive window feature to hide the system windows, including the status bar and navigation bar. To achieve this effect, you can use the immersive window feature, which is available only for the main window of an application.
To create a better video watching and gaming experience, you can use the immersive window feature to hide the system windows, including the status bar and navigation bar. This feature is available only for the main window of an application.
### How to Develop
1. Obtain the main window.
Call **getMainWindow** to obtain the main window of the application.
2. Implement the immersive effect. You can use either of the following methods:
- Method 1: Call **setWindowSystemBarEnable** to hide the navigation bar and status bar.
- Method 2: Call **setWindowLayoutFullScreen** to enable the full-screen mode for the main window layout. Call **setWindowSystemBarProperties** 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.

3. Load content for the immersive window and show it.
Call **loadContent** to load the content to the immersive window.
```ts
importUIAbilityfrom'@ohos.app.ability.UIAbility';
exportdefaultclassEntryAbilityextendsUIAbility{
onWindowStageCreate(windowStage){
// 1. Obtain the main window of the application.
letwindowClass=null;
windowStage.getMainWindow((err,data)=>{

console.error('Failed to obtain the main window. Cause: '+JSON.stringify(err));
return;
}
windowClass=data;
console.info('Succeeded in obtaining the main window. Data: '+JSON.stringify(data));
// 2. Use method 1 to implement the immersive effect.
console.error('Failed to set the system bar properties. Cause: '+JSON.stringify(err));
return;
}
console.info('Succeeded in setting the system bar properties.');
});
})
// 3. Load the page content to the immersive window.
windowStage.loadContent("pages/page2",(err)=>{
if(err.code){
console.error('Failed to load the content. Cause:'+JSON.stringify(err));
return;
}

### How to Develop
1. Apply for permissions.
To create a floating window (of the **WindowType.TYPE_FLOAT** type), you must configure the **ohos.permission.SYSTEM_FLOAT_WINDOW** permission in the **requestPermissions** field of the **module.json5** file. For more configuration information, see [module.json5 Configuration File](../quick-start/module-configuration-file.md).
> **NOTE**
>
> If the task for creating the floating window is reclaimed by the system, the floating window will no longer be displayed. If you want the floating window to be displayed in such a case, apply for a [continuous task](../task-management/continuous-task-dev-guide.md).
```json
{
"module":{
"requestPermissions":[
{
"name":"ohos.permission.SYSTEM_FLOAT_WINDOW",
"usedScene":{
"abilities":[
"EntryAbility"
],
"when":"inuse"
}
}
]
}
}
```
2. Create a floating window.
**Prerequisites**: To create a floating window (a window of the type **WindowType.TYPE_FLOAT**), you must request the **ohos.permission.SYSTEM_FLOAT_WINDOW** permission. For details, see [Declaring Permissions in the Configuration File](../security/accesstoken-guidelines.md#declaring-permissions-in-the-configuration-file).
1. Create a floating window.
Call **window.createWindow** to create a floating window.
3. Set properties for the floating window.
2. Set properties for the floating window.
After the floating window is created, you can set its properties, such as the size, position, background color, and brightness.
4. Load content for the floating window and show it.
3. Load content for the floating window and show it.
Call **setUIContent** and **showWindow** to load and display the content in the floating window.
5. Destroy the floating window.
4. Destroy the floating window.
When the floating window is no longer needed, you can call **destroyWindow** to destroy it.
