ivi_hmi_controller::workspace_control

workspace_control(seat: object<wl_seat>, serial: uint)

参数	类型	描述
seat	object<wl_seat>
serial	uint

开始由服务器控制 surface

通过服务器控制 surface 的参考协议。为了通过服务器控制 surface，它将 seat 交给服务器，例如用于控制主屏幕。主屏幕有几个工作区用于分组 wayland 应用的启动器。这些工作区绘制在水平长的 surface 上，通过输入设备的动作来控制。例如，当发生从右到左的动作时，ivi-shell 中使用 ivi-layout 控制 surface 的视口。客户端可以通过 "workspace_end_control" 事件识别控制结束。

ivi_hmi_controller::switch_mode

switch_mode(layout_mode: uint)

参数	类型	描述
layout_mode	uint

请求切换应用布局模式

hmi-controller 加载到 ivi-shell 实现了 4 种布局类型作为参考：平铺、并排、全屏和随机。

ivi_hmi_controller::home

home(home: uint)

参数	类型	描述
home	uint

请求显示/隐藏主屏幕

主屏幕是用于启动 wayland 应用的启动器的参考实现。主屏幕有几个工作区用于分组 wayland 应用。通过在 weston.ini 中定义以下键，用户可以向工作区添加启动器图标来启动 wayland 应用。 [ivi-launcher] workspace-id=0 ：要添加启动器的工作区 ID icon-id=4001 ：用于绘制图标的 ivi_surface 的 ivi ID icon=/home/user/review/build-ivi-shell/data/icon_ivi_flower.png ：图标图像的路径 path=/home/user/review/build-ivi-shell/weston-dnd ：wayland 应用的路径

workspace_end_control(is_controlled: int)

参数	类型	描述
is_controlled	int

通知工作区控制结束
