Question

在AHK中，如何获取表示键盘上每个键状态的布尔值数组？

Answer 1

不同的键盘布局带有不同的键。您必须知道密钥的名称才能检查它们，并且必须按键完成。你基本上会使用GetKeyState("KeyName","P")。

如果你想检查一组键，你可以循环键数组，cehck每个键并将结果存储在另一个数组中：

keysToCheck = ["q","w","e","r","t","y","u","i","o","p"]
keyStates = {}
for i, key in keysToCheck
{
    keyState := GetKeyState("KeyName","P")
    keyStates.Insert(key,keyState)
}

; keyStates now contains all the key states

MsgBox % keyStates["q"]
MsgBox % keyStates["w"]

Answer 2

我找到了一个惊人的AHK脚本，可以监控所有按下的键和键盘快捷键组合和鼠标点击，脚本很长但是你可以获得全部键盘动作的状态。

如果您从KeypressOSD.ahk脚本查看代码行GuiControl, , HotkeyText, %HotkeyStr% - 那么此%HotkeyStr%是您接收按下的值的变量。

如果你改变代码一点点 - 并删除一些Gui的代码行+写下这个%HotkeyStr%值对于Windows注册表，您可以每次从注册表获取一个代码行的密钥按值并使用它，然后在任何类型的ahk脚本中。

您可以替换它并删除一些GUI代码行。

RegWrite, REG_SZ, HKEY_CURRENT_USER,software\GetKeypressValue,KeypressValue,%HotkeyStr%

现在您可以在任何带有一个代码行的ahk脚本中使用它。（注意 - 与KeypressOSD.ahk脚本一起运行）

 RegRead, KeypressValue, HKEY_CURRENT_USER,software\GetKeypressValue,KeypressValue ; read KeypressValue

如果你看看这个Youtube视频，你可以看到它能做什么。

Detect Keypress Value From Windows Registry key.
