WinEvent库 – 轻松检测窗口打开、关闭、移动等，案例补充

在中文社区找到了[AHK V2]WinEvent – 简单的检测窗口打开关闭、移动、最大化、最小化等 – AutoAHK

但是缺乏案例，我这里就补充一些：

示例 1：
等待创建并显示新的记事本窗口。这也可以使用WinEvent.Create来实现，但是除了记事本主窗口之外，还创建了一些其他隐藏窗口，这些窗口与我们不想捕获的“ahk_exe notepad.exe”匹配。对于记事本，我们可以使用“ahk_class记事本ahk_exe notepad.exe”来筛选主窗口，但该方法不可通用，因此 WinEvent.Show 是一个更安全的选择。

#Requires AutoHotkey v2
#include WinEvent.ahk

; Detects when a Notepad window is created. Press F1 to run Notepad and test.
WinEvent.Show(NotepadCreated, "ahk_class Notepad ahk_exe notepad.exe")
Persistent()

NotepadCreated(hook, hWnd, dwmsEventTime) {
    ToolTip "Notepad was created at " dwmsEventTime ", hWnd " hWnd "`n"
    SetTimer ToolTip, -3000
}

F1::Run("notepad.exe")

示例 2
检测新创建的记事本窗口的关闭。请注意，使用“A”而不是 WinExist（“A”）将检测任何活动窗口的关闭，而不是记事本。第三个论点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"
; Close Notepad to activate
WinEvent.Close(ActiveWindowClosed, WinExist("A"), 1)
Persistent()

ActiveWindowClosed(*) {
    MsgBox "Notepad window closed, press OK to exit"
    ExitApp
}

示例 3
检测任何窗口的最大化时间。

#Requires AutoHotkey v2
#include WinEvent.ahk

; Detects when any window is maximized
WinEvent.Maximize(WindowMaximizedEvent)
Persistent()

WindowMaximizedEvent(hook, hWnd, dwmsEventTime) {
    if MsgBox("A window was maximized at " dwmsEventTime ", hWnd " hWnd "`n`nStop hook?",, 0x4) = "Yes"
        hook.Stop()
}

F1::Run("notepad.exe")

示例 4
检测活动窗口何时更改并显示有关激活窗口的信息。

#Requires AutoHotkey v2
#include WinEvent.ahk

WinEvent.Active(ActiveWindowChanged)
Persistent()

ActiveWindowChanged(hook, hWnd, *) {
    ToolTip "Active window changed! New window info: `n" WinGetInfo(hWnd)
    SetTimer ToolTip, -5000
}

/**
 * Gets info about a window (title, process name, location etc)
 * @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
 *  1: Additionally returns TransColor, transparency level, text (both hidden and not), statusbar text
 *  2: Additionally returns ClassNN names for all controls
 * @param WinText Same as AHK WinText
 * @param ExcludeTitle Same as AHK ExcludeTitle
 * @param ExcludeText Same as AHK ExcludeText
 * @param {string} Separator Linebreak character(s)
 * @returns {string} The info as a string. 
 * @example MsgBox(WinGetInfo("ahk_exe notepad.exe", 2))
 */
