[QGIS-Developer] How to force 'json(tree)' widget in feature info panel

[Richard Duivenvoorde]

Hi Devs,

Working with an api which returns json, we thought to make it possible to see the returned (small) json documents as a json tree widget (like you for example can see in a SensorThingsApi identify result, see screendump).

So creating a memory layer using and setting the providers attributes using a QgsField like:

QgsField(name="json",  type=QMetaType.QVariantMap, typeName='json', len=0, prec=0, comment="", subType=QMetaType.QString)])

(for which I stole type and subtype en typename from a layer which was showing the json widget...)

But in the featureinfo result the 'json'-field keeps being show as a plain string.

Am I missing some detail? Or magic?
Or is this something not possible with Memory Layers?

Any hint is appreciated.

Regards,

Richard Duivenvoorde

  
PS recently I was also asked by somebody if there was a plugin or widget which was able to show the result of an rest/json api call (upon clicking on a feature) in some kind of treeview (like Postman or even browsers) too...
I think some standard way of talking to simple api's from within QGIS would be a good thing to have..
