Define Win key + Mouse scroll as hotkey

Recommended Posts


Hello, folks!

I'm trying to define Win key + Mouse scroll (up and down) as hotkey in my script, but after a deep search in the forum, and many topics about set mouse events as hotkey, I still haven't found a solution to this specific scenario.

I tried _IsPressed internal function, and also MouseOnEvent, MouseTrapEvent and HotKeySetEx UDFs, and all of them work fairly well, but apparently just for single mouse events, and not combined like I need to (a modifier key + a mouse scroll movement).

I also read something about mouse hooks, dll call, and complex stuff like that, but my knowledge about these things is very limited, so I decided to ask here for help.

What I got so far, and is working incredibly well, is unfortunately a solution that came from the "competitor" (AutoHotKey):

WinWaitClose, ahk_class AppClass

#If WinActive("ahk_class AppClass")
#WheelDown::SendPlay X
#WheelUp::SendPlay Y

It took me just minutes to learn how to do this in AHK, but it's kinda sad that with all these years coding with AutoIt, I didn't get a solution as simple as this one, but I really want to do all the code inside AutoIt, if possible of course...

In case you want to know, the purpose is to use this combination of keyboard modifier + mouse scroll to change brush properties in Photoshop.

Thanks in advance,

I find it "kinda sad" that after having been a member here for over 10 years you could not find a solution which took me about 10 minutes to produce:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <Misc.au3>

HotKeySet("{ESC}", "_Exit")

Local $hDLL = DllOpen("user32.dll")

GUICreate("", 0, 0, 0, 0)


While 1

Func _WM_MOUSEWHEEL($hWnd, $iMsg, $wParam, $lParam)

    #forceref $hWnd, $iMsg, $lParam

    Local $iDelta = BitShift($wParam, 16) ; Mouse wheel movement
    If _IsPressed("5B", $hDLL) Then ; If Left Win pressed <<<<<<<<<<<<<<
        If $iDelta > 0 Then
            ConsoleWrite("Down" & @CRLF)
            ConsoleWrite("Up" & @CRLF)


EndFunc   ;==>_Scrollbars_WM_MOUSEWHEEL

Func _Exit()

And not a "mouse hooks, dll call" in sight..... By the way, at the moment it only works for the left Win key - adding the right Win key I leave as "an exercise for the student", as my old maths teacher used to say.

Again, sorry for my lack of knowledge, but trust me, I did a lot of reading about this subject, and didn't find a solution, or maybe the solution was right in front of me, and I didn't see it...

About your code, I don't use SciTE, so I just replaced ConsoleWrite for MsgBox, but I guess it's ok, right?

Unless I miss something, the code works, but with a big drawback: The Win key is still triggering the Start menu when I release the key, stealing the focus of the active window, and the Start menu stay open until I close it manually.

I tried messing with different values of SendKeyDelay and SendKeyDownDelay, and replace the MsgBox with an actual Send, but it seems that didn't make any difference.
Also, I tried replacing MsgBox for ToolTip, believing that could be something related to timing, but the issue is the same.

As you can see, I'm trying to make my exercise, but as I said before, I really want to keep studying in AutoIt school, despite the lessons are quite hard to solve sometimes... :)
