移除或添加指定菜单栏中的选项

这段代码实现了 动态管理窗口菜单栏 的功能。通过 AutoHotkey 和 Windows API 的结合，可以对窗口菜单栏进行以下操作：

1. 移除菜单栏中的选项（F1）。
2. 动态添加菜单栏选项（简易版和高级版）（F2 和 F3）。
3. 支持嵌套子菜单，如在菜单项中创建子菜单。

F1::
WinGet, hHwnd, id, ahk_class AHKEditor
hMenu := DllCall("GetMenu", "uint", hHwnd)
; 点进菜单栏某项，再按F1删除
DllCall("User32\DeleteMenu", "ptr", hMenu, "uint", 0, "uint", 0, "int")
Return

; 这是添加最外部的菜单栏选项【简易限制版】
F2::AppendMenu("ahk_class AHKEditor", 1000, "testing")

AppendMenu(WinTitle, ItemID, ItemName) {
  hWndTarget := WinExist(WinTitle)
  hMenu := DllCall("GetMenu", "Ptr", hWndTarget, "Ptr")
  DllCall("AppendMenu", "Ptr", hMenu, "UInt", 0x0, "UPtr", ItemID, "Str", ItemName)
  DllCall("DrawMenuBar", "Ptr", hWndTarget)
}

F3::

hWnd := getHwndForPid(pid)

MyMenu := AddMenuPopup(hWnd, "&Foo")
AddMenuItem(hWnd, MyMenu, 1001, "Apple")
AddMenuItem(hWnd, MyMenu, 1002, "Banana")

DllCall("AppendMenu", "Ptr", MySubMenu, "UInt", 0, "UPtr", 1004, "Str", "Banana2")
Return

AddMenuPopup(hWnd, MenuName) {

  hMenu := DllCall("GetMenu", "Ptr", hWnd, "Ptr")
  DllCall("AppendMenu", "Ptr", hMenu, "UInt", MF_POPUP, "UPtr", hItem, "Str", MenuName)
  Return hItem

  MF_BYPOSITION = 0x400
  MF_SEPARATOR = 0x800

  DllCall("InsertMenu", "UInt", MenuName, "UInt", 0x0, "UInt", MF_BYPOSITION | MF_STRING, "UInt", ItemID, "Str", ItemName)
  DllCall("SetMenu", "Ptr", MenuName, "Ptr", hMenu)
  DllCall("DrawMenuBar", "Ptr", hWnd)
}

getHwndForPid(pid) {
  pidStr := "ahk_pid " . pid
  WinGet, hWnd, ID, %pidStr%
  return hWnd
