 Hi all,
 
 It seems that when using background, \startitemize[columns] does not work as 
 expected: there are no columns, and the numbers of the items are pushed to 
 the left. 
 
 You can use the columns environment (which is used by itemize) in a framed, 
 framed text or background environment.

Thanks Wolfgang for your attention.
Now that you mention this, I understand that the columns environment cannot be 
used at the same time as framed or background environments. Is this a definite 
barrier? 
As a matter of fact changing background to textbackground (as you suggested) 
did not work neither.

Have a nice day: OK

It’s not a limitation of the mechanism \startcolumns uses to make multiple 
columns because the same mechanism is also used by \startsimplecolumns but of 
the implementation of the command. When you search the list archive you can 
find examples with streams which permit columns in \framed etc.

Thanks fo rthe explanations: indeed with my previous setups for having each 
exercise with a vertical rule at its left, the following modification works 
fine when I need items in two columns:

\startsimplecolumns
\startitemize[r,packed][margin=standard,stopper=,left={(},right={)},distance=1em]
\item $3x - 5 = 4$.
\item $(x-1)(x+3) = 5$.
\item $2 - 3x \geq 2 x - 8$.
\item $(x - 1) \leq (x-1)(x+2)$.
\item $2x^2 - 3x +1  0$.
\item $x^2 - 4x \geq x - x^2 - 1$.
\stopitemize
\stopsimplecolumns

Best regards: OK

[NTG-context] \startitemize[columns] broken with backgrounds?

2012-01-22 Thread Otared Kavian 
Hi all,

It seems that when using background, \startitemize[columns] does not work as 
expected: there are no columns, and the numbers of the items are pushed to the 
left. 
Below is a not so minimal example: the resulting PDF can be found here:
http://dl.dropbox.com/u/4316076/enumeration-background-exo.pdf
I am not sure whether this behaviour began with a recent beta or  not. 
The version I am using is: ConTeXt  ver: 2012.01.16 18:33 MKIV.

Best regards: OK
