Pointer warp
此全局接口允许应用程序请求将指针移动到相对于 wl_surface 的位置。
请注意，如果所需行为是将指针限制在某个区域或锁定在某个位置，则此协议无法提供可靠的方法来实现。在这些用例中，应改用指针约束（pointer constraint）和指针锁定（pointer lock）协议。
警告！此文件中描述的协议当前处于测试阶段。向后兼容的更改可能会与相应的接口版本升级一起添加。向后不兼容的更改只能通过创建扩展的新主要版本来完成。
warp_pointer(surface: object<wl_surface>, pointer: object<wl_pointer>, x: fixed, y: fixed, serial: uint)
参数 | 类型 | 描述 |
|---|---|---|
| surface | object<wl_surface> | surface to position the pointer on |
| pointer | object<wl_pointer> | the pointer that should be repositioned |
| x | fixed | |
| y | fixed | |
| serial | uint | serial number of the enter event |
请求 compositor 将指针移动到表面局部位置。 compositor 是否接受该请求由具体实现决定，但它应该：
- 如果表面具有指针焦点，则接受该请求，包括它具有隐式指针抓取的情况
- 如果 enter serial 不正确，则拒绝该请求
- 如果请求的位置在表面外部，则拒绝该请求
请注意，enter serial 对于客户端的任何表面都是有效的，并且不必来自指针被 warp 到的表面。
