1# Window Manager
2
3## Introduction
4
5The Window Manager subsystem provides basic capabilities of window and display management. It is the basis for UI display. The following figure shows the architecture of the Window Manager subsystem.

9![WindowManager-subsystem-architecture](./figures/WindowManager_EN.png)
10
11- **Window Manager Client**
12
13    Provides window object abstraction and window management interfaces, and connects to the ability and UI framework.
14
15- **Display Manager Client**
16
17    Provides display information abstraction and display management interfaces.
18
19- **Window Manager Server**
20
21    Provides capabilities such as window layout, Z-order control, window tree structure, window dragging, and window snapshot, and offers the window layout and focus window for multimodal input.
22
23- **Display Manager Server**
24
25    Provides display information, screenshot, screen on/off, and brightness processing control, and processes the mapping between the display and screen.

15![窗口子系统架构图](./figures/WindowManager.png)
16
17- **Window Manager Client**
18
19    应用进程窗口管理接口层，提供窗口对对象抽象和窗口管理接口，对接原能力和UI框架。
20
21- **Display Manager Client**
22
23    应用进程Display管理接口层，提供Display信息抽象和Display管理接口。
24
25- **Window Manager Server**
26
27    窗口管理服务，提供窗口布局、Z序控制、窗口树结构、窗口拖拽、窗口快照等能力，并提供窗口布局和焦点窗口给多模输入
28
29- **Display Manager Server**
30
31    Display管理服务，提供Display信息、屏幕截图、屏幕亮灭和亮度处理控制，并处理Display与Screen映射关系
