Thanks for the summary Simon.

Great stuff. Do you think Luca's patch is ready to be committed with this 
change? Or is more testing required?

Thanks,

Chris

No. Without this change other childLMs than TextLM cause an infinite
loop, because null is returned but the childLM never finishes. This is
a special feature of getChildLM(): It is a sort of iterator over the
childLMs but it does not advance to the next childLM except when the
current childLM is finished. With this change the childLM declares
itself finished immediately, without contributing any breakposs. A
real null implementation. :-)

A way must be found to let childLMs other than TextLM contribute to
the Knuth algorithm. Some LMs simply contribute a box. Others,
esp. InlineStackingLM, contribute text elements from their own TextLM
childLMs. These must be forwarded to the LineLM, and the LineLM must
be able to request hyphenation from those TextLMs. This is not
trivial. I expect that Luca is working on it. If not, someone else
must take it up.

Regards, Simon

Simon, thanks for the full explanation.

combining border-right, border-left in table-cells with background-color in table-rows

------- Additional Comments From avogt <at> s-und-n.de  2004-06-02 21:18 -------
After some code study ... , problem occured to me:
the background rectangle gets drawn over the border of the cell to the left and
to the top. those borders get drawn first. the background rect dimension and
position does not account for any existing borders (see
AbstractRenderer.doBackground()). thats no problem for the current cell since
its borders get drawn later.

border computations are ok.
background-color rectangle is wrong.

Problem: the cell needs to know if its left or its upper neighbor have borders!
Only then does it have to make the background rect smaller.

Re: InlineLMs


Simon, thanks for all the information.

At the moment, I am working on LeafNodeLM (now fo:leader works)
and InlineStackingLM.
I think I'll be able to post a second patch next week.

Regards
    Luca
