separator -> splitter

Comment 3

[Emilio Cobos Álvarez (:emilio)]

I don't have a Windows dev env and apparently this is Windows only (that's why I missed it in bug 1417200 :/).

If someone can look into it soon, that'd be nice, otherwise I can take care of it after the All-Hands.

Comment 4

[Patrick Brosset <:pbro>]

This impacts the storage inspector tool in DevTools pretty negatively, so I;d really love to have this fixed in 59. Looks like the merge is sometimes in January, so that should leave us enough time.
Emilio: is this a bug that needs to be fixed in the code that landed with bug 1417200, or are there things that need to be done in devtools CSS to apply the right styling again?

Ideally devtools would stop using -moz-border-*-colors, yeah.

Comment 6

[Julian Descottes [:jdescottes]]

For the record, devtools is just using XUL splitter elements that happen to use -moz-border-*-colors on windows. https://searchfox.org/mozilla-central/source/toolkit/themes/windows/global/splitter.css

Dão, what do you think about this? It removes the -moz-border-*-colors rules where the -moz-appearance isn't 'none' and not used, like in your button.css cleanups. On the other places I used normal border-color rules.

Does -moz-appearance: listbox; not take care of the border on Windows?

Bug 1417200 also added borders to dropdown menus (in about:preferences, about:addons etc), see attachment.

Will this bug solve also this issue, or it should be tracked separately? Thank you!

Oops, let me finish that comment. Does "forced -moz-appearance: none;" mean that normally this styling wouldn't be used?

Comment 15

[Richard Marti (:Paenglab)]

The menupopup has the -moz-appearance set here: https://dxr.mozilla.org/mozilla-central/source/toolkit/themes/windows/global/popup.css#22

And panel[type="arrow"] here: https://dxr.mozilla.org/mozilla-central/source/toolkit/themes/windows/global/popup.css#32

But the plain panel has nothing set. The panel[type="autocomplete"] and the panel[type="autocomplete-richlistbox"] have set it to -moz-appearance: none here: https://dxr.mozilla.org/mozilla-central/source/toolkit/themes/windows/global/autocomplete.css#20 but  override the border-colors.

Good you ask, I see now that I can change autocomplete.css to border-color too. Updated patch follows this evening.

Comment 16

[Richard Marti (:Paenglab)]

Attachment: Bug1423453.patch

The -moz-border-*-colors removed in autocomplete.css

Doesn't this use -moz-appearance: menupopup;?

Could also remove the background-color. AFAIK it's unused just like the border.

I wonder if we should just set border: 1px solid ThreeDShadow; here just like for panel[type="autocomplete"].

No, it uses the -moz-appearance: none; from menulist > menupopup. But the background color is already defined in menulist > menupopup

These border color choices seem a bit weird. Shouldn't these popups just use ThreeDShadow?

Comment 20

[Richard Marti (:Paenglab)]

I can't say how it looks as I don't know how to activate it. I only checked it in Inspector. Do you have a STR to show it?

This popup is used for <select> elements in the content area (e.g. on this bugzilla page).

Comparison of the ContentSelectDropdown popup with GrayText border on the left and default -moz-FieldText border on the right.

I think the GrayText fits better to the border of the <select> item.

That's why I said threedshadow. Graytext and -moz-FieldText are text colors, so they don't really make sense here.

border-color: ThreeDShadow; is redundant now (and padding: 0; too?)

Does setting background-color work here? On Linux it didn't, so I dropped this and just changed the text color to GrayText.

The Certificate Manager and Device Manager in their standalone dialogs of TB and SM uses it.

No, removed. And changed the color also to Graytext. This also fixes bug 1327899.

Is !important needed here? It wasn't on Linux.

The border around this tree is from this rule.

Why does that tree not use -moz-appearance: listbox?

Strange, when I tried it this morning it changed the border color, now not. So removing the border rules.

Question. With beta and nightly, the menus have a flat appearance: https://i.imgur.com/zYi7sAu.png
Shouldn't they match the rest of Windows 7 (Classic Theme) and look like it does in 58: https://i.imgur.com/a7mmWNK.png

The regression test I ran pointed to this causing that change. Just wanting to know if going away from 3D appearing menus was on purpose or if it's a bug?

Kind of on purpose, in that we wanted to simplify the code. There's no Classic theme in recent Windows versions, so it's basically on life support now until Microsoft and Mozilla drop support for Windows 7.
