[QGIS-Developer] Loading layer from specific table/view after running algorithm

[Raymond Nijssen]

Hi developers,

I have created a processing algorithm in python that creates a new gpkg 
database with a bunch of tables and views. One of the views can be 
loaded as a polygon layer, which works fine when loaded manually.

How can I tell QGIS to load that view as a polygon layer when the 
algorithm has finished? (I think it must be the same as telling the 
layername to load from the geopackage)

So far, I have tried both QgsProcessingParameterFileDestination and 
QgsProcessingParameterVectorDestination as output parameters without 
much luck.

Hope anyone can help. Kind regards,
Raymond
