Creating custom layouts using base commands

Usually the pre-defined layouts that SDAPS provides are sufficent. However, there may be special cases that need more customization. Such customization is possible, but it does require a more in depth understanding of LaTeX and the SDAPS packages.

If you do this, please make sure to properly test the output. The easiest way of such testing is to use the annotate command that SDAPS provides, as it visualises the view that SDAPS has of the questionnaire. Doing this testing is essential as small errors and even side effects of how LaTeX executes code may render the information about the questionnaire useless!

Even seemingly “simple” environments like tabularx may not be usable together with SDAPS!

General question structure

To define a question, you need to define 1. the start of the question and its type, 2. the possible answers to the question 3. the checkboxes and textboxes, and finally 4. the end of the question.

A very simple example might look like the following.

[15]Variable[1]=1

Question with one checkbox

Please have a look at the resulting document and the generated metadata. In particular, please note:

• The export shows “QObject-Choice” this is from the Choice specified and denotes the question type

• The name argument does not show up. It only needs to match the one at the end and primarily serves error detection purposes.

• SDAPS will see the question as “Exported question text” with one answer “check”

• The checkbox is automatically exported including its coordinates

Warning

Be careful! The below example shows the effect that tabularx has. This environment expands its content multiple times, and the result is that the automatic numbering breaks; making this the 3rd question rather than the first! Other subtle errors like this can occur with certain environments, so make sure to double check everything is OK!

The different question types

Headings

This is the easiest case, and it can be used for structuring the document.

For example, the \section command simply calls \sdaps_qobject_begin:nnn { section }{ Head }{ #1 } and \sdaps_qobject_end:n { section } for you. Something similar happens for the choicegroup and other grouping environments where a heading is defined for all questions.

Multiple choice

The simple multiple choice question is of type Choice. We already saw the first example earlier. Simply add more checkboxes and answers as needed. SDAPS will match each checkbox to one answer in the order that it finds the defintions.

Multiple choice question using itemize

Note that we placed a textbox rather than a checkbox as one of the possible answers.

Single choice

We can also define a single choice question. For this, we need to make two small adjustments. The first is to use the Option question type. The second is to tell SDAPS that we would like to use the singlechoice style for checkboxes.

The checkbox style change will be in effect for the scope of the question.

Single choice question using itemize

Note that we placed a textbox rather than a checkbox as one of the possible answers.

Ranges

Quite often one has single choice question which represent a value on a range. One could create these using the Option type question, but with Range it becomes more convenient.

Range questions can contain a single range and further answers like “Not applicable”.

The range is specified with a separate command. For the purpose of this command, the first and last box that is part of the range needs to be specified. This is done with a zero based index (i.e. the first checkbox is 0, the second 1, …).

Range question

Note that lower must always be the earlier checkbox. You can however assign different values to each checkbox using the second parameter to the checkbox command, thereby redefining the numeric value. The main different to the Option question is simply how the question will be represented in the report.

Codeboxes

There is experimental support for code boxes, that is not yet available using a nice wrapper. This can be used to create QR code read fields.

Example LaTeX codeResultMetadata

\myquestionbegin{name}{Text}{This is a QR code question}
\mysettextboxtype{codebox}

Place barcode sticker into the box:
% Note that we use hspace + vrule for sizing here, that is a bit weird but
% a reasonable method of setting a size
\mytexthbox{}{3bp}{ \hspace{8cm} \vrule width 0pt height 3cm depth 2cm }
