+	// 【诊断 · 新建商品弹框「输入文字消失」（Win10 触摸键盘）】
+	//
+	// 现象：手指点触摸键盘输入，已输入的字（尤其中文输入的组合串）会消失；
+	//       鼠标点同一个键盘则完全正常。
+	//
+	// 已确认的代码事实（不用日志就能确定的）：
+	//   · 文本**真实存放**在 CEditWnd —— 一个原生的 EDIT 子窗口里（WS_CHILD），
+	//     DuiLib 只通过 EN_CHANGE 把内容同步回 CEditUI::m_sText；
+	//   · 该窗口的生命周期**极短**：只要它失去键盘焦点，
+	//     CEditWnd::OnKillFocus 就会 PostMessage(WM_CLOSE) **把它销毁**；
+	//   · 所以"谁在这一刻抢走了焦点"就是本问题的全部答案。
+	//     一旦焦点离开 EDIT，输入法正在拼的字会被撤销（中文尤其明显），
+	//     之后到达的字符也无处可去 —— 用户看到的就是"输入完被自动删除"。
+	//
+	// 因此下面这几个 helper 只做一件事：把"抢焦点的是谁"记清楚。
+	// 判读要点：
+	//   · 若 EDIT-KILLFOCUS 的 newTid != selfTid ⇒ 焦点被**别的进程/线程**抢走
+	//     （触摸键盘 TabTip / TextInputHost 是首要嫌疑）；
+	//   · newClass 是 "#32770" ⇒ 被我们自己的弹框拿走了；
+	//   · 若同一个 owner 出现 INIT → FIN → INIT 的抖动 ⇒ 窗口在反复重建，
+	//     重建时用的是 m_sText（可能落后于 IME 的组合状态）⇒ 字就"没了"。

+	//   …… 几十毫秒后 ……
+	//   EDIT-FIN                 窗口还是被那条排队的 WM_CLOSE 销毁了
+	//
+	// 也就是说：**焦点刚被抢回来，窗口照旧死掉**。而 CPaintManagerUI::SetFocus 有
+	// `pControl == m_pFocus` 早退，不会再发 UIEVENT_SETFOCUS ⇒ 窗口不再重建。
+	// 触摸键盘敲出的字符、退格、输入法候选词的提交，就全都失去了落点
+	// （真机日志里对应"9.7 秒零条 EDIT-CHANGE"）。
+	//
+	// "手指点虚拟键盘"之所以必现、鼠标不犯，是因为手指点它的那一刻本窗口会短暂失活
+	// （WND-ACTIVATE wParam=0(INACTIVE) fg=00000000 + EDIT-KILLFOCUS newFocus=00000000），

+	//              （那些路径都会先 SetFocus(NULL) 或把 m_pFocus 置 NULL）
+	//              ⇒ 按原设计销毁。
+	//
+	// 为什么必须延后：CPaintManagerUI::SetFocus 的顺序是
+	// 「先 ::SetFocus(画布窗口) 让旧编辑窗失焦 → 再派发 KILLFOCUS → 最后才把 m_pFocus 换成新控件」。

+				//      **把原生 EDIT 子窗口销毁**（EDIT-KILLFOCUS newFocus=00000000
+				//      newTid=0 sameProc=0 ⇒ 焦点离开了本线程）；
+				//   3) 等我们重新被激活时，那个子窗口**已经不存在了**；而
+				//      CPaintManagerUI::SetFocus 有 `pControl == m_pFocus` 早退，
+				//      不会重发 UIEVENT_SETFOCUS ⇒ **没有任何路径重建它**
+				//      ⇒ 用户体感"切一次输入框之后就再也输不进去、连退格都无效"。
+				//   4) CEditUI::DoEvent 收到 UIEVENT_SETFOCUS 后会自己补建/补焦点
+				//      （m_pWindow == NULL ⇒ new CEditWnd；否则 Show+SetFocus）。
