137341 - selecting multiple items in form listbox scrolls to first selection

Status: RESOLVED FIXED

(Core :: Layout: Form Controls, defect)

Description

[Andrew Schultz]

seen in Linux build 20020413
if you have one item selected near the top of a lisbox list, scroll down and
ctrl- or shift-select another, it scrolls back to the first selection.  this is
confusing and makes it difficult to select multiple items.

steps to reproduce:
1) open bugzilla query page
2) select OS "All"
3) scroll down and select "Linux"

build 20020410 did not have this problem, but 20020411 does.

this bug does not occur in build 20020413 (1.0 branch)

backing out the patch for bug 64165 fixes the problem.

It's definitely caused by the scroll-to-focus code, but I wouldn't have expected
that to happen ... it should use mEndSelectionIndex, which is pointing to the
thing you CTRL+selected or SHIFT+selected.

Backed one the ScrollTo in the the SetFocus that was causing this. It should be
fixed now

REOPENING
I'm afraid that without the one line, things are worse.

1) go to bugzilla query
2) select OS "All"
3) scroll down, ctrl-click "Linux"
4) scroll down, ctrl-click "OSF/1"
5) HANG (before OSF/1 is selected)

CVS 2002041521.   backing out the one-line patch returns it to the original
behavior of this bug.

This works fine for me on Win2k and Linux and doesn't hang.

Er, sorry, that was WinXP 2002041603 :)

[Andrew Schultz]

first two times I tried this I got the hang immeadiately.  Just now, I tried
again and it worked for a long time, but eventually, I still got the hang.  Will
attach a stacktrace.

Comment 10

[Andrew Schultz]

Attachment: stacktrace

doesn't look particularly relevant to this bug.

Comment 11

[Andrew Schultz]

I seem to remember a few times that I have had a similar experience (ctrl-click
selecting in a listbox==>hang) with older builds and the stack looks irrelevant
to this bug.  In fact, I just managed to get build 20020410 to hang, so I'm
going to file a new bug.

re-resolving this as fixed!
