[NTG-context] metafun problem

2010-07-13 Thread Albrecht Kauffmann 
Dear ConTeXtuals,

the following MP-inclusion produces fatal error (! TeX capacity
exceeded, sorry [parameter stack size=6000].):

starttext
\startMPcode
label(btex $\underbrace{a}_{b}$ etex,(0,0));
\stopMPcode
\stoptext

I use mkii, but the code should work.
Has anyone an explanation?

With many thanks for any hint
Albrecht

I've got the context minimals installed and I'm compiling the

\startuniqueMPgraphic{name}

p:=unitsquare xscaled OverlayWidth yscaled OverlayHeight;
fill p withcolor .625yellow;
draw p withcolor .625red;
\stopuniqueMPgraphic

\starttext
Hello, World!

\defineoverlay[my graphic][\uniqueMPgraphic{name}]
\button[background=my graphic,frame=off]{Go Home}[firstpage]

\stoptext

No button shows up. Am I missing something?


A \button is an interactive element, so you need to add

\setupinteraction[state=start]

I don't know.
\framed works

\starttext
Hello, World!

\defineoverlay[my graphic][\uniqueMPgraphic{name}]
\button[background={my graphic},frame=off]{Go Home}[firstpage]
\framed[background={my graphic},frame=off]{framed Go Home}
\stoptext
test-arnold.tex (END)

[NTG-context] Metafun problem

2009-09-25 Thread David Arnold 

All,

I've got the context minimals installed and I'm compiling the  
following (from the new Metafun manual) using MKIV:


\startuniqueMPgraphic{name}
path p;
p:=unitsquare xscaled OverlayWidth yscaled OverlayHeight;
fill p withcolor .625yellow;
draw p withcolor .625red;
\stopuniqueMPgraphic

\starttext
Hello, World!

\defineoverlay[my graphic][\uniqueMPgraphic{name}]
\button[background=my graphic,frame=off]{Go Home}[firstpage]

\stoptext

No button shows up. Am I missing something?
