In AHK, how to get the array of boolean values representing the state of every key on the keyboard?
2 Answers
Different keyboard layouts come with different keys. You have to know the names of the keys in order to check them and it has to be done key by key.
You would basically use GetKeyState("KeyName","P")
.
If you have an array of keys that you want to check you could loop ofer the key array, cehck every key and store the results in another array:
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"]
(untested)
I did find an amazing AHK Script that can Monitor All your Pressed keys and keyboard shortcuts combinations and Mouse clicks, The Script is long but then you are able to get the state of All the keyboard movements.
if you look to the Codeline GuiControl, , HotkeyText, %HotkeyStr%
from the KeypressOSD.ahk script - then this %HotkeyStr%
is the variable where you recieve the Value what you did pressed.
If you Change the Code a litte bit - and remove some Gui's codelines lines + write this %HotkeyStr%
value
to the Windows Registry, you can then get everytime the key press value from the registry with one codeline and use it, then in any kind of ahk scripts.
You can Replace this and remove some GUI codelines.
RegWrite, REG_SZ, HKEY_CURRENT_USER,software\GetKeypressValue,KeypressValue,%HotkeyStr%
Now you can use it in any ahk script with one codeline. (note - run it together with KeypressOSD.ahk script)
RegRead, KeypressValue, HKEY_CURRENT_USER,software\GetKeypressValue,KeypressValue ; read KeypressValue
If you Look to this Youtube Video you can see what it can do.
Detect Keypress Value From Windows Registry key.
note!! This program was created by Author RaptorX. And It works on Windows 10 System.
KeypressOSD.ahk
; KeypressOSD.ahk
; Open this Script in Wordpad and For Changelog look to the Bottom of the script.
;This code works with a getkeyname from a Dllcall (See Bottom Script- by Lexikos)
;you can press the esc key to exit.
