Dash - Implement *overlay scrollbars* in Dash. Existing scrollbars are too thin to grab on to.

Bug Description

Note: prior to fixing this bug, bug #1050959 needs to be fixed first.

----------------

Add overlay scrollbars to the Dash. The scrollbar behaviour should be identical to Cimi's GTK overlay scrollbars. Use vertical white line for the position indicator see https://chinstrap.canonical.com/~sabdfl/12_10/desktop_and_netbook/Dash/Home/dash_home_v1.png for visual design (as opposed to vertical orange line in the GTK version).

Contact Roise for the thumb visual assets.

Note that the overlay scrollbar needs to be positioned on top of the dash background texture.

Assigning to Otto; Otto, please add visual information to the Dash spec, and deliver assets.

Designed scrollbar - a lightweight design without steppers - including (from left to right) off/over/down states.

Beautiful stuff Otto, +1

Sorry, not signed off yet.

Is this work now dropped for the Natty cycle?

This work has been confirmed as being in scope for the Natty cycle.

Tested today, and the new style scroll bars are not currently implemented in the Dash. Reverted to triaged.

amended title for clarity

John, I think opening a new bug for this is better and will show up better on the radar. Since the current unity is a rewrite and this bug refers to the old unity, a new bug will make handling the issue in a better way. You can assign me to the new bug again.

I've linked the two new branches relevant for the re-implementation for this to the bug. Next time opening a new bug, instead of reopening this one, would avoid confusion. Since the last unity-version, we switched to a new foundation, which would justify opening a new bug for it... although the visual might have stayed the same.

This bug was fixed in the package unity - 3.6.8-0ubuntu1

@om26er; could you revert this bug to 'confirmed' in Unity, thx

Closing this bug (marking as "Won't fix") because there have been newer designs, which got implemented.

But it's really incosistent to not give the Dash overlay scrollbars.

@macslow; I think this is the bug that tracks the implementation of the new style overlay scrollbars in the Dash, so I hope you won't mind me re-opening.

Scrollbars in Unity e.g. Dash are too thin AND don't have any "up" and "down" arrows or triangles. These scrollbars could easily be mistaken for vertical lines that don't actually do anything, except add decoration to the background!

I've updated the bug's title to reflect the change from the initial bug-description, since the old wasn't closed and a new one created. Like mentioned the initial bug was filed against the clutter/mutter-implementation of unity and in between there have been many visual design-changes to the scrollbars, unity ported to a new foundation (compiz/nux) and the design now demands overlay-scrollbars to be also usedin the dash.

Since the dash uses nux, this needs a nux-implementation of overlay-scrollbars. The initial implementation for the rest of the desktop is gtk+-based and can't be used inside the dash.

The bug-title no longer reflects the description, which got updated and is lacking any real information, about what to change/fix.. Am I expected to figure out myself what's actually required?

From looking at the 12.04 mockups, I don't know if the scrollbar on the right (of the filters) is really expected to give the user the clue that it'll scroll the results view, which is much farther to the left. Is this really the desired layout?

What's meant with "padding"? Padding what element againt what? Scrollbar against what other elements? 12px gap against left side to the filters?! Flush against the right edge of the dashs decoration?!

A single mockup doesn't show how the scrollbar is expected to move with the content... especially in the edge-cases (being at the top and being at the bottom of the results view).

How far does it go up/down?

There should be two scrollbars: one for the content and one for the filters (like the current implementation).

The scrollbar for the content is shown here:
https://chinstrap.canonical.com/~sabdfl/11_10/desktop_and_netbook/dash/file/file_lens_17_08_11_02.png
* It shows (thus what needs tweaking):
- the positioning of the scrollbar at top
- its top padding between the search box
- It doesn't seem to add any sort of padding with the filters (in fact, it's an overlay)
- its horizontal position and the margin with the content on left and filters on right
- [ the top padding of the first category (in the current implementation there is more padding between the search box and the first category/scrollbar) ]
- I would say that the scrollbar should be as tall as its scrollable area (scrolled window)

The scrollbar for the fiters is shown here:
https://chinstrap.canonical.com/~sabdfl/12_04/desktop_and_netbook/dash/tweaks_dash.png
* It shows (thus what needs tweaking):
- the horizontal positioning of the scrollbar (touching right edge of the dash)
- It doesn't seem to add any sort of padding with the filters (in fact, it's an overlay)
- I would say that the scrollbar should be as tall as its scrollable area (scrolled window)

Please contact me in IRC If anything of these is not satisfying or you need any more info.

There are 2 files showing the position of scrollbar

1. when filters is off

2. when filters is on

Where are the overlay scrollbars? I'm running Unity 5.8 and I still get just the thin little lines for scrollbars that are hard to grab; no handles or anything.

This bug is not fixed

same here. not fixed for me.

John, shall we open a new bug only for overlay scrollbars?

Otherwise this bug is fixed

Click and drag inside the dash helped me scroll it pretty easily. However, overlay scrollbar for dash should be good, too. I'm using Unity2D.

Works great! The visual cue is what is important.

The light-grey blends with theme.

Good job. Bug fixed!

@om26er; could we move the importance of this bug back up to critical, it is very very difficult for users to scroll the Dash by clicking and dragging the scrollbar, and this presents a critical problem for users without mouse scroll wheels, or without trackpads that support multi-touch gestures.

ok, sure ;-)

Thanks for considering this critical! I couldn't agree more:

How can I delete a comment?

Some general philosophy towards increasing scroll-bar widths in modern applications:

When will we likely see this rolled out in an official Ubuntu Recommend Update to 12.04 and 12.10 (at least)?

the answer to that is probably never, new features are not allowed for SRU and this change is not simple.
