bind is not possible

[fedorovenskiy]

it is not possible to bind this effect, and this is very important to not open system settings every time I need to disable|enable this function

@fedorovenskiy, what does binding refer to in this context?

@BEEDELLROKEJULIANLOCKHART,
I suppose it means that you can login, and the effect will be active right from the start.
But I don't yet know how to do that.

here's a solution If what you mean by bind is a way to toggle the effect through a keyboard shortcut. i'm on kde 5.27.5.
the terminal command for toggling it.
qdbus org.kde.KWin.Effect.WindowView1 /Effects org.kde.kwin.Effects.toggleEffect kwin4_effect_grayscale

1. Go here and click Command/url
   
2. Copy qdbus org.kde.KWin.Effect.WindowView1 /Effects org.kde.kwin.Effects.toggleEffect kwin4_effect_grayscale in the Action tab and on the Trigger tab add your shortcut key.

I was looking for this answer in theory, but that command returned Cannot find 'org.kde.kwin.Effects.toggleEffect' in object /Effects at org.kde.KWin.Effect.WindowView1 for me.

Here's what worked for me:

• Create a filename.sh with the following code:

#!/bin/bash
greyscaleEnabled=$(kreadconfig5 --file ~/.config/kwinrc --group Plugins --key kwin4_effect_grayscaleEnabled)
kwriteconfig5 --file ~/.config/kwinrc --group Plugins --key kwin4_effect_grayscaleEnabled $((!$greyscaleEnabled))
sleep 0.2
qdbus org.kde.KWin /Compositor suspend
qdbus org.kde.KWin /Compositor resume

• Put sh path/to/filename.sh in the Action tab mentioned above

Thank you to @RomanMunar and to iceman7789 from the comments at the KDE Store for helping me get to a solution that worked with my setup!

Yeah would add that I had installed mine manually(instruction on README) and not from the KDE store 👍️

Oh yeah, me too. I only found out that it was on the KDE Store when I was searching for shortcut solutions. I think it should work either way though.
