Hi Peppe,
You have also a selection tool that makes it possible to select features
by type.
And "layer properties" which displays the number of features of each
type (maybe the more close to what you're looking for, but I don't know
what is your exact use case)

Hi,
You found a use case for in-memory H2GIS layer that Michaël was
dreaming about a few days ago. Then you could use SQL somehowl like
“SELECT DISTINCT geometry_type(the_geom)…”
Meanwhile you could study what Edit – Extract – Extract layers by
geometry type does. Now it already sends a message if there is nothing
to split, perhaps you could modify it to tell if there IS something to
split, but disable the creation of new layers.

Schema) is made by a single geometry type
Thanks for the answers.
I want to develop a way to check if a selected vector layer has
different geometries or if it is if one geometry type.
I checked on OJ code but I didn' t find what I needed.
I will study an alternative way.
Best regards
Peppe

afaik when OJ loads data and is aware that there is only one geom
type in a collection it creates the Multi* variant.
apart from that you must probably loop over all contained geoms
and detect yourself. a prexisting code would probably do nothing else.
