display ticket description with better style

old style tooltip until VikiTicketCalendarMacro? version 1.1.4 rendered by Opera 9.64

I stumbled over this while doing heavy code lifting for a solution to #7239.

So I tried to improve this a bit, but marking line breaks did not do much better. I wasn't satisfied a all with the results. The old style tooltip is simply not suitable to display more than the first line of ticket description text.

minor enhanced old style tooltip for WikiTicketCalendarMacro, again rendered by Opera 9.64

Now I found the time to re-implement ticket descriptions in tooltips by pure CSS.

This is not my own invention but actually a quite widespread solution, that should work with many browsers ¹

I noticed some quirks when scrolling the wiki page with the calendar in Opera 9.64 from Debian package, but since Opera 10 is out for a while I guess this could have improved since too.

¹ examples I used to build the current solution for WikiTicketCalendarMacro:

• http://www.tool4web.de/css_tooltip.html
• http://www.webbe.de/index.shtml?CONTENT=script_css_tooltip (German or Polish only)

major enhanced tooltip CSS style, rendered by Opera 9.64 as well

With [8165] all wiki formatting is shown nicely, even AbbrMacro (TracAbbrMacro-0.11.1) works inside the new style tooltip pop-up.

Please test and report back any issues, since I'd like to make this the new default description presentation. Someone voting to retain the old tooltip as an option, or switch descriptions off entirely (not possible by now, but could be done).

(Mis-)Rendering hyperlinks (href) and CSS (span) around embedded images was a major show stopper for new style tooltip pop-ups in all tested browsers (IE6.0 + 7, FF3.5, Mozilla1.0.9, Opera 9), hence they are stripped now by regular expression. I restored the old ticket entry look (red link and blue summary) as well, that was altered accidentally by me carelessly adding way too many style attributes together with essential CSS for tooltips.

[8189] might be the final step in this development as I'm satisfied with the presentation now.

As I still miss feedback on this I strongly encourage everyone to test now. If I see no further issues testing here on my own, I'll release new branch revisions for 0.11 and 0.12 within next two weeks. For now I still think about stripping images embedded into ticket description from tooltips. Small ones are nice, but big ones (i.e. screenshot images) do blow up the tooltip boxes to an enormous size. At least Opera has big issues with rendering such mega-boxes in a consistent, usable way.

[8200] has some more polishing for the tooltip rendering, especially in older versions of IE.

As for a nasty z-index related render bug I feel forced to move the tooltips to the left much more than I'd like normally (actually had 'left: 0;' before), but I see no other way to prevent following ticket numbers from popping up in the tooltip box of tickets listed above (see http://www.quirksmode.org/bugreports/archives/2006/01/Explorer_z_index_bug.html for details on the issue).

(In [8263]) WikiTicketCalendarMacro: Copy trunk to 0.12 and merge changes to 0.11 as well, closes #7239 #7236 #3159 #7304.

This is a major push to get latest development into both currently maintained branches. Next to a lang rewrite for saner HTML generation there is a new approach to ticket description preview by native CSS style text boxes. Expect some more subtle tweaks to calendar presentation as well.
