Scrollbar steppers

Hello

Desktop: Xfce v: 4.18.1 tk: Gtk v: 3.24.36 info: xfce4-panel wm: xfwm v: 4.18.0 vt: 7
    dm: LightDM v: 1.26.0 Distro: MX-23.2_x64 Libretto January 21  2024 base: Debian GNU/Linux 12
    (bookworm)

Is there a way to bring the arrows in addition to the scrollbar into the GUI.
I would like to have them for GTK2, GTK3 and ev. GTK4

Would appreciate some answer.

Thank you.

Edit:
I have tried this in ~/.config/gtk-3.0/gtk.css:
scrollbar {
  -GtkScrollbar-has-backward-stepper: true;
  -GtkScrollbar-has-forward-stepper: true;
  }
scrollbar button {padding: 0}

But this makes not the full job.

Re: Scrollbar steppers

Can you explain what you mean by "not the full job"? What is missing?

Also, steppers don't exist in GTK4 (see: https://discourse.gnome.org/t/gtk4-gtks … gone/14376).

Re: Scrollbar steppers

Thank you for asking.

1) Thunar: If the scrollbar is on the extreme down position, the stepper is weak:

I would like, that it is still strong like the upper.

2) Thunar:
When I click on the arrow, I would like, that it moves one line like in GTK2 apps. But it only moves some pixels in thunar:

3) GTK2-Apps:
It does not show the arrows, but if I click, where the arrows should be it works as expected:

But I would like to see also arrows there.

I think this is default GTK3 behaviour when there is no more to scroll. You can override it by changing the last line of your snippet to:

scrollbar button {padding: 0; color: red;}

...and change "red" to whatever colour you would like.

2) Thunar:

I have a sense that this is just the way GTK3 changed things related to scrolling. I'm unable to find any information on how to disable or revert this functionality.

3) GTK2-Apps:

It's been soooo long since I've done any GTK2 tweaking. What gtk2 theme are you using and do you have any content in ~/.gtkrc-2.0?

Re: Scrollbar steppers

Unfortunately, the Arc gtk-2.0 theme doesn't implement the steppers. Here is how the Chicago95 theme implements them. Notice that it uses the pixmap engine to specify the graphic elements for the function "STEPPER" - you'll need to re-create this functionality for the Arc theme.

Re: Scrollbar steppers

Thank you!

I see it needs the folder Scrollbars with the pics and the file "scrollbar.rc".

Re: Scrollbar steppers

But maybe I should just take another theme.
