43722 - Slew of CSS in XUL bugs, tree, html:div, treecell, more

Status: VERIFIED INVALID

(Core :: XUL, defect, P3)

Description

[Eric Murphy]

I have attached 2 files. One XUL, and one HTML for comparison, except for the 
tree part of it.

I have commented the XUL file, but here are the probs.

1. html: element all have a border around them that should not be there!
2. html:div relatively displayed have height of 100%!
3. absolute positioning not displayed at all.
4. treecells of 100% not doable, used to be
5. tree problems overall of doing 100%
6. etc, etc.

Also, I have colored the boxes to make it easier to compare.

I am trying to do some nice designs in XUL, but these are holding me up big 
time.

Thanks!

The green border is intended to point out cases where HTML elements are used, 
rather than the preferred XUL equivalent.  This is deliberate.  Convert your 
html widgets to their XUL counterparts and you won't have that problem.

There are many bugs on the absolute positioning problem.  Bug 39082 comes to 
mind (see the testcase URL there).

These are all separate issues, and independent of each other.  They really 
should be split up into separate bug reports.

Reassigning to hyatt since most of the remaining problems deal with trees, but I 
assume john will be able to explain further (or give dups of) the remaining bugs 
that I didn't mention.

:-( on the HTML elements with a green border. box just does not behave like 
html:div. I think we should be able to use either, what is the difference?

The main prob (for me) with box is that it does not work with absolute or fixed 
positioning. Is this a bug?

Then there are the tree issues...

? Wow, just straight <div> seems to work in XUL? Fine with me, it that is the 
way it is supposed to be... haha

XUL is not HTML.  It has its own spring-and-strut layout system that uses flex 
rather than percentages.  Trees are no longer based off of HTML tables (which is 
why percentages coincidentally worked for you before), and are now properly 
based off boxes.

The green border around HTML in XUL is intended for debugging purposes to ensure 
that we minimize the use of HTML in our XUL files (since XUL is much more 
efficient and simpler than HTML because it uses a simplified layout system).

So nothing I've heard is really a bug here except for the absolute/relative 
positioning problems, and there are many bugs already filed on those issues.
