Squashed scrollbars

[Goodydino]

What makes scrollbars too narrow in some themes? I have tried trading scrollbars.css and global.css from other themes which have wide scrollbars and it does no good.

I'll babble...

Something like there are two types of full themes
Some, "Classic" in SeaMonkey speak, are fine
Others, "Modern" in SeaMonkey speak, are affected this way

Long standing bug (in SeaMonkey).
(Not finding the associated bug, at present.)


(New Tobin Paradigm, I would think could say this more succinctly.)

Don't see any problems here, on any themes with custom scrollbars. Taking your Halloween theme for example, on macOS:

Off-topic:
You should use display:none on the #titlebar on macOS for your theme, to remove those weird caption buttons in non-private/persona windows. I'd usually suggest something like this:

Code: Select all

/* ensure titlebar on privacy windows is of correct size */
#titlebar {
  height: 22px;
}

/* ensure extra titlebar doesn't appear on normal (e.g. non-privacy) windows */
#main-window:not([privatebrowsingmode=temporary]):not(:-moz-lwtheme) > #titlebar > #titlebar-content > #titlebar-buttonbox-container,
#main-window:not([drawintitlebar=true]):not(:-moz-lwtheme) > #titlebar {
  display: none;
}

#titlebar-spacer {
  display: none;
}

#titlebar-buttonbox-container {
  margin-left: 7px;
  margin-top: 3px;
}

#main-window:-moz-lwtheme > #titlebar {
  -moz-appearance: none !important;
}

#titlebar-close {
  -moz-box-ordinal-group:1;
}

#titlebar-max {
  -moz-box-ordinal-group:2;
}

#titlebar-min {
  -moz-box-ordinal-group:3;
}

You need to increase / decrease the page zoom level to see the affect.

Well, that's scary .

On my end, on install, scrollbar did not display at all.
(On the particular page I reopened to. [And that is due to the particular zoom level for the page.])
Ctrl++ got it to display, then subsequent Ctrl++'s cause the scrollbar to enlarge (incorrectly).


Might have a look on bugzilla.mozilla.org -> SeaMonkey end, for scrollbar size related bugs.
(I didn't find it offhand.)


This Bug 1066934 FF32: Skinned scrollbars thumb disappear upon scrolling a page at specific zoom percentage (different between FF themes) is marked as Fixed on the FF end, so there must be a similar bug on the SeaMonkey end...

It's probably this, Bug 401213 The full page zoom changes the size of XUL scrollbars with non-native themes.

I have added the suggested code to browser.css in Halloween.

I was not talking about the scrollbars in Halloween. They are fine. If I put Halloween's scrollbar images & stylesheet into the theme I am working on, the scrollbars are narrower than they should be. This does not seem to affect an in-page box like code, but it does affect the scrollbar for the whole page. I was not zooming the page.

[Goodydino]

I found the cause: it was tabbox.css causing the problem. I substituted that from another theme and the scrollbars returned to normal.

I would advise instead you make OS-specific versions of that file and put it in the OS X one. If you put that in the main browser.css it will surely break Windows entirely.

[Goodydino]

I put your code into a Darwin browser.css, but I did not put much in for Linux and nothing for Windows, since I have very little knowledge of those. Is that enough?

[Lootyhoof]

That would work.

The page zoom level should have nothing to do with it. It should just work with the default zoom level.

Those ultra-narrow scrollbars have been a big problem to me since I started using Linux, years ago. I find them everywhere, not just in Pale Moon and they seem to be standard. And I don't get it, in Windows they look normal (or what's normal to me anyway - a scrollbar which doesn't require all your attention when you use a touchpad rather than a mouse).

I'm not sure if this could help, but I use NewScrollbars (aka NoiaScrollbars) 1.2.8
And it give me all sorts of options.

Perhaps that could help fix the issue?

[Goodydino]

I solved my problem by substituting tabbox.css. What I do not understand is why something that is supposed to control the appearance of tabs would have any effect on scrollbars.

[therube]

Pale Moon scrollbar size at various zoom levels; minimal, default, maximal.
Now it might be a different issue then what you were looking at, but there is an underlying issue that affects themes more generally.
