154234 - problems when you make the folder pane "too narrow"

Status: RESOLVED WORKSFORME

(SeaMonkey :: MailNews: Message Display, defect)

Description

there are problems when you make the folder pane "too narrow".

this is a bit hard to explain, so I'll attach a screen shot.

if I grab the folder pane splitter and make the folder pane too narrow, I can
end up in a state where we paint things poorly (looks like some z order
problems, see screen shot).

the splitter (when I drag it to the left) appears to go under the folder pane
scroll bar, under the folder pane tree.  note, the message pane (in the screen
shot, the white area in the bottom right) draws over the tree.

it also makes it so you can't click on the splitter grippy.  (clicking on that
area registers a click on the tree, probably because the tree is "on top of" the
grippy).

to get out of this state, you need to grap the splitter way up at the top.

I think I've got a work around that works:  specify a min-width on the
folderTree.  I believe this bug is on the trunk and 1.0 branch.

note, a side effect of setting min-width is that when dragging the splitter 
over from right to left, we appear to "snap shut" the folder pane at that min 
width.  

I think that's a desired side effect, but others may disagree.

sending this UI polish bug over to ssu.

as I mentioned, the min-width thing fixes that but we should:

1) verify that min-width is the right approach.  I think it will be for mozilla 
1.0.1 / netscape 7.0, since it is low risk and that work is on the branch.  
this might be a common tree bug (we should see what the tree experts think), 
and the real fix for it would be to some other code, and that would be for the 
trunk.

2) verify that other places don't have this problem.  for this bug I think we 
need to fix messenger.xul and alternate 3 pane (or maybe just the 
folderPane.xul overlay?).  the addressbook doesn't seem to have this problem, I 
did notice that I can get a similar painting issue with the bolded "Address 
Books" painting into the quick search area.

The Sidebar seems to have a min width. Its snaps to the left edge when it 
reaches a certain size.

Sidebar in the Browser that is.

As I noted in bug 57752, the later attachment does seem to be the same problem 
as this one, but not necessarily related to that bug.

At any rate, the folder pane does not exhibit these problems now, and does show 
the minimum-width behavior described in comment 2.
