Props for the SegmentedControl component.
分段控件。
胶囊轨道里放一组选项,当前项下是浮起的滑块,切换时以 snappy 弹簧滑到新位置。 ←/→ 在选项间循环并立即切换,Home/End 跳到首尾,焦点随之移动(roving tabindex, Tab 只停在当前项)。滑块测量完成前(含服务端渲染与 hydration 首帧),当前项直接 画浮起底色,首屏不闪。
Props:
items:选项列表,见SegmentedItem;既可传Vec,也可传信号或闭包(数量变化时 选项按序号原地更新、不重建按钮,焦点不丢)value:当前值(值、信号或闭包);没有匹配项时没有当前项on_change:切换时的回调aria_label:控件组的无障碍名称kind:语义,Tabs(默认)或 Radio,见SegmentedKindsize:Md(默认)或 Smicon_only:只显示图标,文字作为 aria-label 与 titleclass:外层容器附加类(间距、页面变体)
带图标且未设 icon_only 时,容器窄于 16rem 自动只留图标(文字仍供读屏)。
容器对宽度有尺寸包含,放进 flex 行时调用方必须给它宽度。
选项按钮不再带 seg-N-i 形式的 id:该序号来自全局计数器,服务端(进程级)与
水合后的客户端计数不一致;焦点移动改为按序号在轨道内查询 .segmented-item。

pub fn builder() -> SegmentedControlPropsBuilder<T, ((), (), (), (), (), (), (), ())>
Create a builder for building SegmentedControlProps.
On the builder, call .items(...), .value(...), .on_change(...), .aria_label(...), .kind(...)(optional), .size(...)(optional), .icon_only(...)(optional), .class(...)(optional) to set the values of the fields.
Finally, call .build() to create the instance of SegmentedControlProps.
