WinEvent简介
WinEvent 可以监视所有窗口或特定窗口的窗口事件。目前支持以下事件：显示、创建、关闭、激活、非激活、移动、开始移动、结束移动、最小化、还原、最大化。有关详细信息，请参见库中函数的注释。
WinEvent.ahk ，以下是2024年5月的版本，该库最新版可在GitHub上获得。
#Requires AutoHotkey v2
/**
* The WinEvent class can monitor window events for all windows or specific windows.
* Currently the following events are supported: `Show`, `Create`, `Close`, `Active`, `NotActive`, `Move`,
* `MoveStart`, `MoveEnd`, `Minimize`, `Restore`, `Maximize`. See comments for the functions for more information.
*
* All the event initiation methods have the same syntax:
* `WinEvent.EventType(Callback, WinTitle:="", Count:=-1, WinText:="", ExcludeTitle:="", ExcludeText:="")`
* where Callback is the function that will be called once the event happened, and Count specifies
* the maximum amount of callbacks.
* The function returns an event hook object that describes the hook (see descriptions down below).
* NOTE: if all WinTitle criteria are left empty then any window will match. To match for Last Found
* Window, use WinExist() as WinTitle.
*
* `Callback(eventObj, hWnd, dwmsEventTime)`
* `eventObj` : the event hook object describing the hook
* `hWnd` : the window handle that triggered the event
* `dwmsEventTime`: the `A_TickCount` for when the event happened
*
* Hook object properties:
* `EventHook.EventType`
* The name of the event type (Show, Close, etc)
* `EventHook.MatchCriteria`
* The window matching criteria in array format `[WinTitle, WinText, ExcludeTitle, ExcludeText]`
* `EventHook.Callback`
* The callback function
* `EventHook.Count`
* The current count of how many times the callback may be called
* `EventHook.Pause(NewState:=1)
* Pauses or unpauses the hook. 1 = pause, 0 = unpause, -1 = toggle
* `EventHook.IsPaused`
* Used to get or set whether the hook is currently active or paused
*
* Hook object methods:
* `EventHook.Stop()`
* Stops the event hook
*
* WinEvent methods (in addition to the event methods):
* `WinEvent.Stop(EventType?, WinTitle:="", WinText:="", ExcludeTitle:="", ExcludeText:="")`
* Stops one or all event hooks.
* `WinEvent.Pause(NewState:=1)
* Pauses or unpauses all event hooks. 1 = pause, 0 = unpause, -1 = toggle
* `WinEvent.IsRegistered(EventType, WinTitle:="", WinText:="", ExcludeTitle:="", ExcludeText:="")
* Checks whether an event with the specified type and criteria is registered.
* `WinEvent.IsEventTypeRegistered(EventType)`
* Checks whether any events for a given event type are registered.
*
* WinEvent properties:
* `WinEvent.IsPaused`
* Can be used to get or set the paused state of all events.

举几个例子
第一个例子 监测WinEvent.Show事件
监测Notepad窗口被创建事件，以Notepad记事本为例，当探测到Notepad窗口创建时，显示一个ToolTip提示。
说明，需要将本脚本与WinEvent.ahk放到同一个目录里进行测试。
#Requires AutoHotkey v2
#include WinEvent.ahk
;检测何时创建了Notepad窗口. 按 F1 启动Notepad 来测试.
WinEvent.Show(NotepadCreated, "ahk_class Notepad ahk_exe notepad.exe")
; WinEvent.Show(NotepadCreated, "ahk_exe notepad.exe",1) ;仅仅监控1次。
Persistent()
NotepadCreated(hook, hWnd, dwmsEventTime) {
ToolTip "Notepad 窗口创建于" dwmsEventTime ", 句柄为" hWnd "`n"
SetTimer ToolTip, -3000
}
F1::Run("notepad.exe")
第二个例子 监测WinEvent.Close事件
监测Notepad窗口关闭事件。请注意，如果使用"A"替换掉WinExist("A")将检测到任何活动窗口的关闭，而不是Notepad窗口。
第3个参数1表示一旦回调函数被调用一次，钩子就会停止。
#Requires AutoHotkey v2
#include WinEvent.ahk
Run "notepad.exe"
WinWaitActive "ahk_exe notepad.exe"
; Notepad窗口关闭时，会回调ActiveWindowClosed。
WinEvent.Close(ActiveWindowClosed, WinExist("A"), 1)
Persistent()
ActiveWindowClosed(*) {
MsgBox "Notepad 窗口关闭了，点击 确定 按钮 退出"
ExitApp
}
第三个例子 监测WinEvent.Maximize事件
监测窗口最大化事件，这里没指定特定窗口标识，将监视所有窗口的最大化。
#Requires AutoHotkey v2
#include WinEvent.ahk
; 监测所有窗口的最大化事件
WinEvent.Maximize(WindowMaximizedEvent)
Persistent()
WindowMaximizedEvent(hook, hWnd, dwmsEventTime) {
if MsgBox("一个窗口最大化于 " dwmsEventTime ", 句柄" hWnd "`n`n停止监控?",, 0x4) = "Yes"
hook.Stop()
}
F1::Run("notepad.exe")
第四个例子 监测WinEvent.Active事件
测WinEvent.Active事件，实现当窗口激活时显示激活窗口的一些信息。
#Requires AutoHotkey v2
#include WinEvent.ahk
WinEvent.Active(ActiveWindowChanged)
Persistent()
ActiveWindowChanged(hook, hWnd, *) {
ToolTip "激活窗口变了! 新窗口信息为: `n" WinGetInfo(hWnd)
SetTimer ToolTip, -5000
}
/**

* @param WinTitle Same as AHK WinTitle
* @param {number} Verbose How verbose the output should be (default is 1):
* 0: Returns window title, hWnd, class, process name, PID, process path, screen position, min-max info, styles and ex-styles
