Hi Stefan, header/footer is a solution but I use another
\def\PageNavig{\setlayer[navbar][x=0cm,y=10cm]{\the\pageno}}
\appendtoks
\PageNavig
\to \everypagebody
for this task.

Hi all,
I use an overlay to implement a navigation bar in the left margin of a
document. It seems to me that the processing of the overlay is done only
once and not for every page again. In addition, the \lastpage is not
available.
Does anyone know a solution? Maybe headers/footers are a solution. But
how is absolute positioning accomplished with them?
Thanks for your attention,
--Stefan
PS: Here is my current implementation:
\definelayer[navbar]
\setupbackgrounds[text][leftmargin][background=navbar]
\setlayer[navbar][x=0cm,y=10cm]{\the\pageno}

Hi Vit,
thanks for the quick help. It works!

Of course:
grep -i "\appendtoks" tex/context/base/*.tex
;-)
\every* are defined/decribed(?) in core-var.tex

page, paper and text backgrounda are calculated each page, unless you
say \setupbackgrounds[state=repeat], in which case all are recalculated;
if you put something in a layer it happens directly (but the layer may
be flushed later)

you can put a layer in the background of the header area and that do
something:
\startsetups whatever
\setlayer[thatlayer][....positioning...]{\the\pageno}
\stopsetups
\setupheadertexts[\setups{whatever}]

lastpage etc only make sense in the output routine (during page building) since one does not know where tex will break the page.

hm, dirty tricks -)
beware of interference, also, be careful not to introduce funny spaces then.
(sometimes \prependtoks is better)

Hi Hans,
I implemented my changing navigation bar like you proposed, i.e. using a
layer that is "refreshed" by the footer text:
\definelayer[navbar]
\setupbackgrounds[text][leftmargin][background=navbar]
\startsetups NavBar
... some quite complicated code setting up the navigation bar layer ...
\stopsetups
\setupfootertexts[\setups{NavBar}]
Everything works now, but I was not able to use the \goto makro inside
the navigation layer setup code. It seems that the \goto makro somehow
interferes with the output routine. Therefore I had to replace the \goto
makro in the setup code with my self written \PrevOrNextPage makro. This
makro writes a "raw" pdftex link. (Sometime ago you hinted me to replace
my \PrevOrNextPage makro by the \goto makro.)
Using the \goto makro I get the following error message:
! Missing } inserted.
<inserted text>
}
<to be read again>
\endgroup
\dosingletexts ...atetexts {#1#2#5}{#6{}{}{}}}}}}}
\egroup

\get...
\dodoplacelayouttextline ... \c!kantlijntekst }}}}
\fi \ifdim
\rechtermargebr...
...
l.211 ...t\crlf{} Die Landesregierung\blank[small]
Can you please have a look on the example? I attach a file that when it
is texexecuted produces the above error. When you comment out line 150
in the file and use line 148 instead, then the example works fine.
Thanks,
--Stefan
