perf: get rid of the scrollboxes / ellipsis hack in autocomplete.xml Until we have bug #312156 (implement text-overflow: ellipsis from CSS3 text), I was planning to do what we currently do, which is to have the description inside a scrollbox, followed by a label. the value of the label is either the localized ellipsis character or "", depending on if the description element is bigger than the scrollbox, see _setUpEllipsis() http://lxr.mozilla.org/seamonkey/source/toolkit/content/widgets/autocomplete.xml#1266 Once we had #312156, or if we had another way of making crop attribute work with description even I don't use the value attribute (see bug #404427), I could remove all those scrollboxes (two per autocomplete item, so 50 in total by default), the additional labels for the ellipsis, and the hacky code to hide/show the ellipsis (which gets called on setTimeout.)
a trick that vlad came up with last week to get rid of the scrollbox: <hbox> <hbox style="overflow-x: hidden;"> <description width="200">aasadfadfasdfasdfadsfadfasdfsssssssa<html:span>test</html:span>bbb</description> </hbox> <label id="ellipsis"/> </hbox> Note, I'm using span instead of label, we're moving to span for RTL issues. using crop="right" on the description will not work, which is bug #404427 (Excuse the shorthand for the ellipsis.)
note, I can't get rid of the ellipsis hack (yet), but I was able to get rid of the scrollboxes, thanks to vlad's suggestion from last week. I'll attach a patch here, but I think this will be part of an bigger patch to use span to address rtl issues with <label> (instead of span).
morphing this bug to cover the scrollboxes. in bug #407944 vlad writes: "Note that you really, really, really want to get rid of the scrollboxes for the final, regardless if things get implemented using selection or something else. They cause a native OS widget to be created per scrollbox." I've got bug #405918 to cover the ellipsis hackery.
