667426 - No tooltips for events with very long description in calendar view (works in unifinder), collapse fast, seem hidden

Status: NEW

(Calendar :: Calendar Frontend, defect)

Description

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Attachment: tooltip test calendar

Windows XP SP 3 32-bit, Thunderbird 5.0 beta 2, Lightning 1.0b4rc1

For some events with very long descriptions, the tooltips in the calendar view don't work (but work in unifinder). The tooltip is shown, but immediately collapses and goes into hiding.

Steps to reproduce:
1. Open the attached test calendar in Lightning.
2. Go to 2011-06-27.
3. Move your mouse over the event in the late evening.

Actual result: Tooltip collapses

4. Switch to 2011-06-28.
5. Move your mouse over the same event in the first hours of the day.

Actual result: Tooltip shown

Confirmed. It seems to depend on the tooltip location on the screen.

Tooltip works if it fits between mouse position and lower screen border. Tooltip doesn't work if it doesn't fits between mouse position and lower screen border.

For example it works correctly if month view shows July 2011 and the test event is located near the top of the screen. It doesn't work correctly if month view shows June 2011 and the test event is located near the bottom of the screen. You can reproduce the problem in Unifinder too if you move it close to the bottom screen border.

in lightning 1.4 the yellow tooltip doesn't show up at all anymore (not even for a milisecond) so there has been a slight change, but the problem has not been solved.
for my workflow a very annoying bug, by the way, sadly I'm only user and no coder...

I was having a similar problem with tooltips not displaying for some events if they're in the bottom part of the window. At least for these events commenting out maxHeight helped (https://hg.mozilla.org/comm-central/file/tip/calendar/resources/content/mouseoverPreviews.js#l166). I haven't seen top of the tooltip off the screen yet as the comment there warns.
