Change transparency by Alt+scroll about glassy-gnome

[emiapwil]

Interesting key binding. I think it is possible and will take a look. Thanks for the info :)

Hi @seriyps ,

After some experiment, I think you can do it with the following commands (in a terminal).

gsettings --schemadir ~/.local/share/gnome-shell/extensions/glassygnome@emiapwil/schemas \ 
          set org.gnome.shell.extensions.glassy-gnome inc-opacity-key "['<Alt>UP']"

gsettings --schemadir ~/.local/share/gnome-shell/extensions/glassygnome@emiapwil/schemas \ 
          set org.gnome.shell.extensions.glassy-gnome dec-opacity-key "['<Alt>DOWN']"

Please let me know if that works.

@emiapwil hi, and thanks

I tried your suggested keybinding, but it uses UP and DOWN keyboard arrows, but I was talking about mouse whell (or touchpad) SCROLL-UP and SCROLL-DOWN. So yep, you hold Alt and scroll mouse wheel and this changes current window opacity.

My mistake. Will check that later.

One possible solution is to map the scroll up/down to a given keycode and use the keycode in the settings.

But I have not figured out how to do the mapping yet.

How GNOME identifies keycode

I am also keen to see this implemented (I remember doing this with <Super> + scroll up).
I don't think mapping should be necessary but I'm not sure how else it could be implemented.

@jcuenod Do you still know how super + scroll-up works? Can I take a look?

[jcuenod]

Well it was in the old compiz days. Looking at xev I'm seeing buttonpress/release events with the button value 4/5 for scrolling up and down. I don't know how to track these things in GJS though. The little I've done with GJS I found it to be total nightmare.
