Re: [NTG-context] Clickable question/answer numbers

2 Nov 2016

      Dear Otared,

thank you again. This is somehow a proof that it should work. In my
real document I use the title to name some exercises (after old
exams), and I don't see how that can be combined with your solution.

If someone else reads this: I think the question boils down to the following:

\startquestion[Q:test]
How can I here automatically get access to to the string "Q:test"?
\stopquestion

Best regards, Mikael

Hi Mikael,
A partial solution to the feature we are discussing is contained in the example below, but somone more aware of ConTeXtish coding might improve it.
It is not satisfactory in that one has to define twice \startquestion and \StartQuestion, \beginanswer and \BeginAnswer, and more importantly one cannot generate automatically the references (I tried \getnumber[question] and such to append to Q:\getnumber[question] for instance, but something does not work…).
Le me know if you find a satisfactory solution…

Prove that $(a +b)^2 = a^2 + 2ab + b^2$ for all $a,b\in{\Bbb R}$.
\BeginAnswer{test}
Indeed $(a+b)^2 = (a+b)(a+b) = a^2 + ab + ba +b^2 = a^2 + 2ab +b^2$ since $ba=ba$.

Dear Otared (and list),
thank you for your reply and support.
The links from the answers to the questions work as wanted with my
solution, it is the links from the questions to the answers that do
not.
I guess I need something like
headcommand={\in{Question}[A:###]},
where ### is the reference tag I set. But I don't know what to change
the ### into (or if that would work).
Best regards, Mikael

Hi Mikael,
I had a similar question some time ago, but I wanted to add a sort of automatic referencing of questions and answers (and interaction going from questions to answers and back).
If you accept the hurdle of adding manual references, in your case you can add (for instance…)
\goto{:-)}[Q:test]
to the end of your answer to go back to the respective question. But when you have several dozens of such references to add manually, it is not a good idea.
However I could not find a way to code the items (that is the questions) in such a way that each adds automatically a unique reference, and so I am interested too in the solution of the problem you mention.
Best regards: OK

Dear list,
I have a pretty large text with a lot of questions and answers, and
want the user(students) to be able to click in the pdf to go from a
certain exercise to its answer, and back. I have a solution (see
below) to go from answers to questions, but not the other way around.
I simply have no idea on how to make the red text (in the head) in the
example question clickable with the answer on the next page as target.
As you can see, the answer has a tag A:Q:test (I want to set these
automatically in that manner), and clicking the green text I get to
the correct place. I just don't see how to make the "Question 1.1"
clickable with that target.
I hope I make myself clear. If it matters, in the solution one could
assume that the optional tag of the \startquestion \stopquestion is
given for all questions.
Best regards, Mikael
