105048 - Mac Style "double arrow" Scrollbars do not appear for divs with overflow

Status: RESOLVED WORKSFORME

(Core :: XUL, defect)

Description

[Andrew Thompson]

Find a Mac running Mac OS 9, set the scrollbar style to "both at one end" (smart
scrolling) in the appearance control panel.

Now, using 0.9.5, and te Modern theme, go to a regular page like
http://www.mozilla.org - all should be well, Mozilla will reflect your scrollbar
preference. If it doesn't, then do a reload (sometimes it fails for the first
page loaded - known bug)

Now go to http://pixel.recoil.org - this is a CSS2 based page with DIV elements
that overflow and show scrollbars. If you resize the window s.t. you can see
scrollbars on the main div in the page, you'll see that you get "one arrow"
scrollbars, rather than the correct style.

(obv. this is likely to effect more than modern running on Mac OS 9 - its
probably universal on Mac OS).

Oh - this is a regression...

Comment 2

[John Morrison]

a regression from when? I tried trunk builds (randomly) from may,june,july, 
august, and I never get a double-ended scrollbar (not that that's not a bug,
just that I don't see where this ever worked.)

You know, you're absolutely right. My bad. (I could swear it used to work...)

Is this still a problem? Is in OS9 only? I couldn't load the recoil.org site,
but on RC2 / OS X the following pages do show scrollbars with arrows together:

ol { overflow:auto }
http://www.neuralust.com/~cac6982/index.php?sheet=10

div { overflow:auto }
http://www.neuralust.com/~cac6982/index.php?sheet=13

(just came across this looking for another bug)

Working for me on OS X with RC2. Need someone to confirm for OS 9 I guess.

In MacOS 9.2.2, build 1.0RC2 (2002051005), the smart (double-arrow) scrollbars
appeared on http://pixel.recoil.org and at
ol { overflow:auto }
http://www.neuralust.com/~cac6982/index.php?sheet=10

div { overflow:auto }
http://www.neuralust.com/~cac6982/index.php?sheet=13
