2989 - [EVENTTARG] Blank areas of elements doesn't fire events

Status: VERIFIED FIXED

(Core :: DOM: UI Events & Focus Handling, defect, P1)

Description

[Erik Arvidsson]

If I have an element with text in the event isn't fired until the text node
fires the event. I'll show a short sample:

    <div style="background-color: yellow; width: 500px; height: 500px;"
onmouseover="alert('K.')">
        Short text
    </div>

The text node fires the event that is then bubbled to the div node but the div
node doesn't fire an event by itself.

per leger, assigning QA contacts to all open bugs without QA contacts according
to list at http://bugzilla.mozilla.org/describecomponents.cgi?product=Browser

QA contact re-assigned according to the product areas we're currently working
on.

The behavior of mouseover isn't really specified to this level.  If I mouseover
the text, I'm going to get a mouseover on the text which will bubble up to the
div.  That's just the way it works at the moment.

There was a separate bug where hitting the rest of the div would not cause an
event at all.  This is fixed now.

This isn't satisfactory from a dhtml developer point of view. This forces me to
fill up the entire container with text which isn't possible (the borders). For
example I can't create buttons, toolbars etc that can be clicked anywhere, only
at the text.

This is almost as bad as when you in NN4.x only provided a background color
behind the text in the container!

No, you still get events on the div.  And if you're not keep in mind I only
marked this fixed today, the change only went in hours ago.  So the deal is

over empty space -> event goes to div
over text -> event goes to text, bubbles to div.

This is the solution.

Not fixt.
I get no alert for this test.  I put the test included in this bug report on
http://slip/projects/marvin/bugs/bug_2989.html for easier reference.

The test doesn't use window.alert. It writes out the the text using DOM and it
worked with 1999-04-22 (maybe something went wrong during those two days?)

I don't see how it becomes more easy when the provided URL doesn't work :-) The
old URL is still available at http://webfx.eae.net/gecko/testEvents.html

Yeah, noticed the change still in my tree.  Must have forgot to check it in.
I'll add it when I can.

It seems to me that the original problem, Blank areas of elements doesn't fire
events, is fixed now. I tested the code in the bug description that was created
by [e-mail] (and I created a test case for the bugathon) on the
daily build for July 26, 1999 on Linux and the blank areas of the DIV fired the
onmouseover events. Can anyone else (maybe a Mozilla engeneer?) confirm if this
is fixed now?

Marking this resolved-fixed.  I think joki checked in the fix sometime between
April and now.  It sure looks fixed.

This bug dealt only with the second test on the page.  However:

I couldn't find any bugs on the other two tests on the page.  The first one is
IE-specific syntax that has been replaced in DOM2.

The problem in the third test area is a dup of bug 11009 and I will add a note
there.
