73137 - [RFE] capability to have half-size scrollbars

Status: RESOLVED FIXED

(Core :: XUL, enhancement)

Description

[marlon bishop]

We need the capability to specify an alternate scrollbar in certain places.   
Allows us to save space in compact places such as the Sidebar, possibly in prefs.

Updating summary.  It's a more general issue of being able to specify different 
CSS for different types of scrollbars - which tiny scrollbars are an example. 
Such kinds of scrollbars appear in IE as well as in various places on MacOS and 
would be useful for places which need as much horizontal space as possible:
AIM, autocomplete, history, etc.

There are lots of ways I can think of to solve this.  One way would be to enable
scrollbars to use the parent selector during style resolution to find the
element which they are scrolling, like "#folderPane > scrollbar" or
".sidebar-panel > scrollbar".

Alternatively, we could specify an attribute on elements called "scrollbarclass"
such that <box scrollbarclass="my-scrollbar"> would allow you to select the
scrollbar with .my-scrollbar.

Ok, this patch enables you to use the parent selector with scrollbars in XUL 
docs, e.g., you can style a treechildren scrollbar by saying

treechildren > scrollbar {
 la la la;
}

Fix checked in.  Enjoy.

See, even though I let super-reviewers have lots of discretion, they need to
enlist at least a rs= (rubberstamp=) in addition to an r=.  I know hyatt
smooched and made up to shaver on IRC, but the problem for rule-makers like me
at mozilla.org is that others (who may or may not be good enough to do without
r= and sr=) will point to this bug and cry foul.

So foul noted, and there'd better be no harm.

Still not quite right.  Need to also handle HTML selectively.

Really fixed.  The attr you can use on <browser> is "usechromesheets".
