Re: [NTG-context] header in the middle on doublesided layout

2010-03-24 Thread Willi Egger

Hi,

her yet my two cents,

May be it is worthwhile to consider a set of setups and using  
layerframed. This gives to my knowledge the most of flexibility.

\setupheadertexts[a]
or
\setupheadertexts[][a][]
but using 6 parameters on double-sided doesn't work.

I am now hacking with
\setupheadertexts[\hbox{\kern-5mm\myheaderright}][][][\hbox 
{\myheaderleft\kern-5mm}]

\def\myheaderright{\hbox to textwidth+10mm{...}}
but that's a bit ugly.

I think mkiv is right, the left page should contain the header (last 
section here) unless specified otherwise.

No, mkii != mkiv at page 2;
mkiv shows 'Section 1.3' at middle  and  'left' at the right side, while
mkii shows only 'left' at the right side.
Now I should say that mkiv is right --- at least it looks more
reasonable than mkii .

[NTG-context] header in the middle on doublesided layout

2010-03-22 Thread Mojca Miklavec
Hello,

I would like to set a different header on left and right page, but I
would like it to be centered on page. How do I do that?

The command
\setupheadertexts[a][b]
puts a b on one page and b a on the other while
\setupheadertexts[a][b][c][d]
puts a b on one page and c d on the other. On single-sided
layouts I could use
\setupheadertexts[a]
or
\setupheadertexts[][a][]
but using 6 parameters on double-sided doesn't work.

I am now hacking with

\setupheadertexts[\hbox{\kern-5mm\myheaderright}][][][\hbox{\myheaderleft\kern-5mm}]
\def\myheaderright{\hbox to textwidth+10mm{...}}
but that's a bit ugly.

 Why don't you use setups ?

I do use setups on the outer level (not on the inner), but that hardly
makes a difference (\setups{Header:Left} and \myleftheader are almost
equal).

\startsetups[header with logo]
  \doifmodeelse
{twosided}
{\setupheadertexts
[\hbox{\kern-5mm\myheaderright}][]
[][\hbox{\myheaderleft\kern-5mm}]}
{\setupheadertexts[\myheaderright]}
\stopsetups

and then another structure full of hboxes, struts  kerns ... but I
find it ugly to use explicit kerning just to get the header alignment
right.

But apparently everyone is hacking with boxes here. That's also OK if
there's no better option.

Thanks,
