render.rs

//! 唯一渲染入口(L2):真实 eframe App 与 kittest 建构走同一个 `render_body`。
//!
//! 布局 v5(BD-UI-29 面板化,官方面板组合;蓝本 = Python 主窗 mainwindow.py):
//! **TopBottomPanel(菜单) → TopBottomPanel(行情带) → SidePanel(下单侧) →
//! CentralPanel(2×2 监控格) → Window 弹窗**,两带物理分离。
//! - 行情带(TopBottomPanel::resizable = Python 分带 splitter 语义,缺省 240):
//!   交易所二级 tab(只列有 tick 的所)+ tick 表(唯一源 = `eTick.`
//!   订阅流,不从 bar 回);行单击 = 带入下单面板(ek 增值,方案钉),行双击 =
//!   弹 K线窗。
//! - 下单侧(SidePanel::resizable,缺省 250):下单面板常驻(Python
//!   TradingWidget 等价:9 字段 + 委托 + 全撤;表单 = 网格,按钮/提示语都是
//!   网格行;网格后置 err label 由 ScrollArea 吸收 sizing 退让,BD-UI-27)+
//!   盘口(买5卖5,Python TradingWidget 内序:字段钮 → 盘口)。
//! - 2×2 监控格(CentralPanel 内,响应式分配,无定宽定高,BD-UI-29)
//!   「委托|未成交」「成交」「持仓」「资金|日志」(撤单钮仅活动行,既有 s11
//!   钉口径;委托行双击 = 撤单,Python OrderMonitor 等价;格内宽表走横向滚动,
//!   D7 口径)。
//! - 弹窗(egui::Window,依附主窗,kittest 可断言):运维窗(菜单「运维」:
//!   插件/服务/依赖/流控查询)、CTP 配置窗(菜单「网关」,CTP 插件自己的
//!   界面)、查询合约窗(菜单「查询合约」:查询 + 勾选 + 订阅钮,Python
//!   ContractManager 等价)、K线窗(双击弹出,按合约多开)。
//! - 订阅两入口(用户裁定,网关窗不定死订阅):下单面板代码框**回车**订阅
//!   (Python returnPressed 等价);查询合约窗**勾选订阅**。合约数据 =
//!   `eContract.` 自动回流(ek-ctp 登录后自动查询,UI 只收不催)。
//! - 回灌表单与票据文本框已退役(界面面);总线口(`UiCmd::Reload` 等)保留。
//!
//! kittest 断言面:各单元格独立 Label(`get_by_label` 直查);操作走
//! `push_cmd` 入队(ui 插件 eTimer 辞行出队),确认状态就地翻位,零自制通道。
//! 隔离红标:行状态含 Quarantin(快照扫描,BD-UI-17)。
