27938 - Scroll wheels scroll page *and* select options at same time

Status: VERIFIED DUPLICATE of bug 33733

(Core :: Layout: Form Controls, defect, P3)

Description

[djoham]

From Bug Helper:
User-Agent: Mozilla/5.0 (X11; N; Linux 2.2.12-20 i686; en-US)
BuildID:    2000021510
Sorry for the crummy summary, but this one is hard to sum up in a single line.

What's happening is when the user clicks in a drop down box (created with the
HTML <SELECT SIZE=1>....</SELECT>), moves the mouse into the area where he/she
could choose one of the options and then scrolls the mouse wheel, the entire
page *including* the options scroll with the wheel. This separates the option
group from its original drop down. I'll include a screen shot and a test case to
demonstrate.

This bug may be related to bug ID 22254.

It's important to note that you have to follow the steps to reproduce exactly,
or you won't see the problem.

I only have Mozilla installed on my Linux partition at the moment. Time
permitting, I'll see if I can recreate this in Windows as well. Since I'm
suspecting this is a XUL problem, it will probably happen there as well.

Reproducible: Always
Steps to Reproduce:
1.Open test case
2.Activate drop down by clicking on down arrow
3.Select one of the options, but don't move the mouse after you do - leave it in
the drop down area.
4.Scroll the mouse wheel down

Actual Results:  The entire page will scroll with the mouse wheel. The contents
of the list box (the options) will also scroll with the page, separating them
from the original drop down box.
Expected Results:  I would desire that while mouse focus (or control focus) is
on the drop down box, the scroll wheel would take effect inside the option list
and move through the selections rather than scrolling the page. However, list
boxes in mozilla don't work that way either so that may be asking too much.

At the minimum, I would expect the same type of behavior that is seen when you
move the mouse outside of the drop down option area and use the scroll mouse. In
this case, the options list goes away the the page scrolls normally.

This sounds to me like bug 24083, which I checked in a fix for on the 17th.  Is
it still happening in current builds?

Still happening on Mozilla build 2000022308 (Feb 23rd Daily Build). RH Linux 6.1 KDE 1.1.2 I'm reopening since bug 24083 is marked as resolved fixed. Should I be re-opening that one instead?

I will take a closer look at this.  I was probably over-zealous in marking it a
dup.

Setting assigned/M15, which is when I hope to have most of the mousewheel / form
control problems ironed out.

Comment 10

[karnaze (gone)]

Reassigning to Rod.

Oops, meant to assign to me.

I have reproduced this.  I also noticed that the same thing happens if you hit
down-arrow instead of moving the mousewheel.  So, reassigning this as a form
controls bug.  I'll keep up on this to make sure that the fix lets the
mousewheel behavior be correct as well.

Assigning this to rods, since that is where karnaze had previously assigned it.

Upping the severity a notch, as people keep reporting this.

Rod, this might go away when gfx scrollbars for selects are turned on.  Do you 
have an ETA for that?

Comment 20

[rods (gone)]

I'm trying to get them turned on for M16, but it is slow going. Something is 
always cropping up with GfxScrollFrame or BoxLayout. evuaghan and I are working 
through the issues.

Comment 21

[rods (gone)]

moving bugs to M17

Comment 22

This is no longer happening for me with mousewheel scrolling, and we fixed the
keyboard case.  Marking Fixed.

Confirming fix on my system.



build 2000050709



Thanks

This has regressed. Linux Build 2000072113. The original test case will
demonstrate the issue.

Comment 25

[Brian Ryner (not reading)]

This sounds like the same issue as 33733 (this bug probably should have been
reopened instead of filing the a new one).

I've already got 33733 nominated for beta3, so do you mind if I resolve this one
as a dup?

Comment 26

[djoham]

hrm.... but it's *my* bug :)

Nope, not a problem. Thanks
