57752 - Corrupted mail folder display when opening 3-pane mail view

Status: RESOLVED WORKSFORME

(SeaMonkey :: MailNews: Message Display, defect, P3)

Description

[Ron Gavlin]

I have 3-pane mail view configured with mail folder top left, message list top
right, and message preview bottom. Whenever I open mail, the mail folder display
is corrupted. I must collapse and then expand a mail folder to refresh the
display. This is painful.

what do you mean by corrupted, do you have a screen shot?

For some reason, the mail/news folders tree pane in the 3-pane view has major
refreshing/painting problems. I don't see the problem with other trees in the
application. Unfortunately, the problem presents itself whenever I open mail for
the first time. It is often a problem when I try to resize the width of the pane
as well.

My attachment is a Winzip file containing 3 BMP files which can be viewed using
the bundled Windows Paint program.

thanks. reassigning to hyatt. It looks like there are some tree paint problems
going on. I haven't seen this in the folder pane except for the case where
scrolling causes it to mess up.

marking rtm need info to get on radar, possibly another symptom of the tree
synch problems Hyatt is currently addressing. If this problem is specific to
that pane arrangement, could we just disable it, or release note it? That isn't
the default, is it?  cc jrgm, selmer

So, there seems to be a problem with either calculating the preferred widths
for that mail window layout style (vertLayout), or with persisting the correct
values to localstore. In general, the folderPane in that layout seems to mostly
come up with a width ~100px no matter what size this was left in when you last
exited the mailnews window.

(However, there are some "magic" widths that do seem to "persist" correctly.
rgavlin -- can you try this. Open the mailnews window and then resize the 
folderPane to be really wide (~350px or so). Then close the mailnews window
and start it up again, and repeat. You should see that the width that appears
on the second open (~180px) will persist through repeated openings.)

At any rate, when that folderPane comes up in the very narrow size, the 
tree is layed out for that width. However, it does not update when the pane
is then widened (like any user would do). But whether the tree were hosed or
not, that unusable width for the folder pane is the bigger bug here, since
a user has to widen that pane everytime (when using the vertical layout style).

Perhaps evaughan can have a look at this. Maybe there is a simple CSS fix for 
this problem. (Otherwise, I think mailnews may need to consider whether they
want to ship this optional layout style, given that it's not usable).

I tried the "magic" folderpane width trick and it worked as John Morrison suggested.

Comment 10

[Ron Gavlin]

I miss the Outlook/Netscape 4.x layout style with the folders available in a
drop-down box. This layout is the closest I've been able to get to my preferred
layout with Mozilla. I hope you don't have to disable it. But, disabling is
probably better than the current behavior.

Scott: the <tree id='folderTree' .../> has a 'style="width:0px"'. Removing
that attribute clears up this problem (checked on linux and windows). I get 
a reasonable width for the folderPane and threadPane when I remove that 
attribute.

I would say that that is the way to go for RTM. (This is more of a box bug
than a tree bug anyways, and the stuff that hyatt is working on will not 
address this problem). 

Attaching a patch for review/test/checkin, etc. and assigning to putterman.
(Leaving [rtm need info] -- this is a very safe fix, and the alternative is 
to ship with vertLayout broken).

marking rtm-. This is not the default view and scrolling the folder pane or 
moving the splitter to the left and back again makes the folder names show up. 
I agree that this is not very good for people who use this view, but I don't 
think it's worth trying to get in. We should try to land this on the trunk 
though.

Is bug 57558 covered by this bug?
I will wait and see when the patch gets into trunk builds.

[Ed Suominen]

I don't know if this is a related problem, but I lost my e-mail folders when
switching to a three-pane mail view (two on top, one on bottom). Everything was
okay at first, but after messing around with the folders a little bit,
everything disappeared and I got a weird looking display. (See screenshot.) I
never did get the folders back, which makes me hesitate to use the e-mail client!

Thanks for all your efforts -Ed

I am experiencing this problem in v.1.5 final. If I chose the alternate
mail/news window view (folder list - left top, message list - right top, message
text full width - bottom) the folder list is corrupt when I open a mail news
session (bunch of ? marks and other punct marks but no visible folder list.

Related/Duplicate to bug 154234 !?

Comment 25

[Mike Cowperthwaite]

I believe Serge is correct in comment 24; Ed Suominen's screenshot looks quite 
similar to the problem in bug 154234.  I'm pretty sure this bug has been 
addressed by the change noted in comment 23.

The original bug may or may not be directly related to this change -- those 
bitmaps appeared to have the pane's content sized more narrowly than the pane 
itself.  At any rate, marking this WFM; anyone is welcome to reopen if they've 
seen that problem in recent builds.  I've never seen it since starting to work 
with Mozilla when 1.0 came out.
