Display prefixes in questions

[jingtang10]

See the pain management questionnaire #196

Spec: https://www.hl7.org/fhir/questionnaire-definitions.html#Questionnaire.item.prefix

At the moment the prefixes are not displayed at all, this causes confusion in some questions where the prefix includes critical information.

For True/False answers rendered as a check box, where will the prefix come? Seems odd if it looks like "Q2 | | Are you feeling happy?"
PS: | | is a checkbox

@jingtang10 where do we want to show prefixes in questions ? please specify. Thanks

[jingtang10]

@MuhammadSalman-7214 yes that's the main focus of this issue. At the moment the prefixes are not handled/shown.

[jingtang10]

updated the description.

[MuhammadSalman-7214]

so, we want to show prefix for every question or with only specific question @jingtang10 ?

[jingtang10]

I believe by default we should just show it for all questions. no reason to hide it for some questions. What do you think?

If you have doubts please feel free to use https://chat.fhir.org/#narrow/stream/179255-questionnaire to ask quesitons about the expecation of the standard itself.

What I'm not sure about is if we should use two different text views or concatenate the strings in one text view. Can you think aboout the pros and cons and write down your thoughts here @MuhammadSalman-7214? Thanks!

[MuhammadSalman-7214]

One thing is if we want to show prefix for each questionnaire, then we have to add the code in all the factory classes to show prefix with question, right @jingtang10 ?

I think rather than two different textviews, we should concatenate the prefix before question text, it's advantage is that we do not have to change xml at all, only the code files will change

[jingtang10]

Yes this will touch all view types.

I'm not sure I necessarily agree we should simply do the easiest thing.

One important consideration is that if the prefix needs to be rendered differently (e.g. different color, size, font) then we would not be able to achieve that if it is in the same text view as the question's text. Do you know if there's ever an expectation that it might need to be rendered differently? Can you do some research to figure this out?

[MuhammadSalman-7214]

I understand your point, but from where should I research or from where should I ask
https://chat.fhir.org/login/#narrow/stream/179255-questionnaire
should I ask on this link?

I have a question, why we don't want to change XML? I believe it can be done with a little more effort using the data binding and conditionally adding the prefixes to the text needed

[MuhammadSalman-7214]

it's not that we don't want to change the xml, currently we are discussing the solutions

[MuhammadSalman-7214]

so how are we going about it @jingtang10 ?

[jingtang10]

did you get a chance to ask the question in the zulip chat stream?

as i said i'm concerned about the customization of styling for prefix and the main question text. so having 2 different views gives more flexibility.

[MuhammadSalman-7214]

posted it just now in the zulip chat stream

so should I start to add text views in every factory class then @jingtang10 ?
