281427 - Tooltips do not disappear when the mouse leaves the parent widget

Status: RESOLVED WORKSFORME

(Core :: XUL, defect)

Description

[Alex Sirota (iosart)]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b) Gecko/20050207 Firefox/1.0+
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b) Gecko/20050207 Firefox/1.0+

In the FoxyTunes extension (http://www.foxytunes.org) there are several buttons
that are placed on the status bar. When hovering over one of the buttons a
tooltip is displayed. When the mouse leaves the button, the tooltip remains
on-screen. Clicking outside the button does dismiss the tooltip.

The problem seems to happen only with toolbarbutton widgets. A statusbarpanel
with a tooltip doesn't cause this problem.

Reproducible: Always

Steps to Reproduce:
1. Install FoxyTunes 1.1 from http://www.foxytunes.org 
2. Hover over the 'play' button until a tooltip appears
3. Move the mouse away from the button


Actual Results:  
The tooltip remains on the screen

Expected Results:  
The tooltip should have been popped down

It is not my call, but this this is a problem with an extension it is
unlikely to be processed here.

The extension is only a test case. The problem is that the tooltip mechanism of
a XUL element is broken, the extension doesn't do anything illegal to bring that on.
I can make a smaller test case if needed, but I don't see the point of that -
there is a test case above that easily reproduces the problem.

Attachment: a minimal testcase part 1/2

A minimal test case that reproduces this problem (and introduces a new one):

1. put this attachment (testcase.xul) and the 
   next one (textcase.css) in  some local directory
2. open testcase.xul in Firefox
3. hover over the "testing 1 2 3" button.

Two problems:
1. The tooltip appears as a small empty box 
   (Firefox 1.0 displays the correct tooltip)
2. When the mouse leaves the button the small box (tooltip) doesn't disappear

The contents of the testcase (for quick reference):
testcase.xul:
<?xml version="1.0"?>
<?xml-stylesheet href="testcase.css" type="text/css"?>
<window xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">
   <toolbarbutton class="testbutton" label="testing 1 2 3" tooltiptext="testing
1 2 3" />
</window>

testcase.css:
.testbutton         { -moz-opacity: 0.99; }
.testbutton:hover   { -moz-opacity: 1;    }


Without the style sheet the tooltiptext appears as an small empty box, but when
the mouse leaves it is popped down. With the style sheet both problems occur
(the tooltip isn't popped down).

Sounds like the reframe for the opacity change confuses the ESM...

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.
