Bug Description

Steps:

1) Open the control center and open User Interface.
2) Move the mouse pointer to the "Launcher icon size" slider.
3) Scroll the mouse wheel upwards.
4) Notice that the slider moves to the left.
5) Scroll the mouse wheel downwards
6) Notice that the slider moves to the right.

This is opposite of how all other sliders work, including the volume control, for instance.

--------------------------------------------
Desired Solution:

The logical incremental direction is left to right (horizontally) and bottom to top (vertically).

Vertically (e.g.: with scrollbars), to move the thumb towards the bottom, we move the finger (on top of the mouse wheel) towards us.

Hence the same movement, when we have horizontal slider, should move the thumb from right to left.

On my current Precise build the Launcher tile in the Appearance panel and the slider in the Sound indicator work fine.

  * debian/patches/04_new_appearance_settings.patch:
    - Wallpapers grid in appearance should have 4 columns (LP: #922542)
    - Change the mouse wheel scrolling on slider to the opposite direction

The original bug is wrong: only audio-related sliders have their scroll wheel direction reversed. With this change, the scroll wheel behavior on sliders in Appearance is different for that in e.g. "Mouse and Touchpad". If we change direction (which we imo should), we should do it for all sliders in gtk.

In addition, the fix was wrong. It broke moving the slider with the scroll wheel all together.

I've reverted the fix in lp:~larsu/ubuntu/precise/gnome-control-center/remove-slider-hacks (together with the left-click-to-position the slider hack, see bug #953757).

Need input from design: should we change all sliders to move to the left when scrolling down?

summary: - Mouse-wheeling "Launcher icon size" slider moves it the wrong way.

Actually, with the new audio dialog, the Volume slider at the bottom doesn't react to scrolling at all. Neither does Balance in the right pane of the Output tab. The slider in the Effects tab also doesn't react. And not per-application audio.

In summary; none of the sliders react on scrolling anymore.
