Actually we have an array inside the stroke (bGPDstroke) with the weights, but this is not visible in the python API and the artists need to read this data.

The actual code in rna_GpencilVertex_groups_begin is not working because it does not display the full array of values. The problem is the "owner" of the data is bGPDstroke and if we move the RNA prop to Point, we are unable to get the Stroke because is not an ID.

RNA_def_property_collection_funcs(prop,
"rna_GpencilVertex_groups_begin",
"rna_iterator_array_next",
"rna_iterator_array_end",
"rna_iterator_array_get",
NULL,
NULL,
NULL,
NULL);
RNA_def_property_struct_type(prop, "GpencilVertexGroupElement");
RNA_def_property_ui_text(
prop, "Groups", "Weights for the vertex groups this vertex is member of");```

@brecht Could you help me with this? I don't know enough of RNA to solve it. Thanks in advance.

Following @brecht advices, I'm going to implement this as a function because expose as array is not efficient.
