change f.lux brightness mouse remote (like Volume²)

[brotherS]

Hello,

I'm using f.lux, which allows you to change the screen brightness with Alt+PgDown/PgUp. I'd like a 'remote' so that I can do those changes by moving the mouse cursor to the left side of the screen and use the mouse scroll wheel (down/up).

I'm using Volume² (http://irzyxa.blogspot.com/p/downloads.html) to change the system volume in that way on the right side of the screen and really like that feature, the same for screen brightness would be great!

Do you have AutoHotkey installed?  If so, try out this simple script:

Code: ( autohotkey)

myEdgePixels := 10

~WheelUp::
~WheelDown::
{
    MouseGetPos, myX
    If ( ( A_ScreenWidth - myX ) <= myEdgePixels )
    {
        If ( A_ThisHotkey = "~WheelUp" )
        {
            SendInput, !{Up} ; Send Alt+Up.
        }
        If ( A_ThisHotkey = "~WheelDown" )
        {
            SendInput, !{Down} ; Send Alt+Down.
        }
    }
}
Return

If you don't have AutoHotkey installed, let me know, and I'll compile this into an executable.  Also, I don't have f.lux installed, so this is untested.

I know F.lux thanks to Techgara and it is quite fortunate to see someone mentioning it here. Btw, does anyone know how to change the time of when F.lux switches between daytime and nighttime mode? I search on that site but no anser. Thanks!

I have AutoHotkey installed, but couldn't get your code to work. No idea why...

An executable would be welcome!

You set your physical location and your "earliest wake time", and based on that f.lux does its thing.

Did you save out the code to a something.ahk file and then run it?

Duh! Of course I did forget to try the simplest approach...

But it still doesn't work.

A logical question:

If I fill
"If ( ( A_ScreenWidth - myX ) <= myEdgePixels )"
with probable values for the left side of the screen:
If ( ( 1920 - 10 ) <= 10 )

doesn't that mean that that line will never be able to trigger the following "If ..."?

I changed it to
"If ( myX <= myEdgePixels )"
and that does trigger the following "If ...".

(15 minutes later)

I also adjusted the Up vs. PgUp (Down vs. PgDn) confusion and added CoordMode so the script would not be triggered on the left border of any window that's smaller than fullscreen size:

Code: ( autohotkey)

CoordMode, Mouse, Screen
myEdgePixels := 10
 
~WheelUp::
~WheelDown::
{
    MouseGetPos, myX
    If ( myX <= myEdgePixels )
    {
        If ( A_ThisHotkey = "~WheelUp" )
        {
            SendInput, !{PgUp} ; Send Alt+PgUp.
        }
        If ( A_ThisHotkey = "~WheelDown" )
        {
            SendInput, !{PgDn} ; Send Alt+PgDown.
        }
    }
}
Return

It works almost perfectly now, just one issue remains: can I 'mute' the wheel output so that when it successfully sends a command to f.lux, it will not also scroll the browser window up or down or change the volume in the media player?

That's quite a nifty workaround.
As to:

...It works almost perfectly now, just one issue remains: can I 'mute' the wheel output so that when it successfully sends a command to f.lux, it will not also scroll the browser window up or down or change the volume in the media player?

- I would be interested to see how that unintended consequence might be addressed.

- I'm not sure whether there is in fact any way to control that, as f.lux seems to automatically take it's day/night switch trigger from calculating where it is on the diurnal/nocturnal cycle depicted in its little chart, which is based on the local timezone. You could try to fudge it by forcing it to a different timezone, I suppose, but that might not seem a very satisfactory approach.

Perhaps this program might be of interest as it has lots of manual and automatic options incl timers to change various settings. Quite a learning curve no doubt but perhaps worth the effort. Per monitor (if I'm not mistaken) and freeware and portable

The issue is that the code isn't sending a command directly to f.lux.  Rather, it's just blindly sending the Alt+PgUp/Alt+PgDown commands.  Try this:

Code: ( autohotkey)

CoordMode, Mouse, Screen
myEdgePixels := 10
 
WheelUp::
WheelDown::
{
    MouseGetPos, myX
    If ( myX <= myEdgePixels )
    {
        If ( A_ThisHotkey = "WheelUp" )
        {
            SendInput, !{PgUp} ; Send Alt+PgUp.
        }
        If ( A_ThisHotkey = "WheelDown" )
        {
            SendInput, !{PgDn} ; Send Alt+PgDown.
        }
    }
    Else
    {
        SendInput, {%A_ThisHotkey%}
    }
}
Return

Again, I don't have f.lux installed so this is untested with that application.

Thank you very much, skwire, it works even more almost perfectly now! Just one tiny issue remains: in VLC, when not using fullscreen mode, the script activates and deactivates the menu with each wheelscroll. It's as if VLC recognizes the Alt from !{PgUp} and !{PgDn} as if the Alt key alone is being pressed. Any idea how to avoid that?
