In GdaNumeric, we added accesors to fields in the struct.
I think you have a GObject implementation. Your way is the best: add
properties to access to fields.
GdaNumeric is a struct with some fields easy to modify directly from
Python, like the integer ones, but the string one is not handle by
Python by default because could be very different per case. Then we
added some API to access to struct members (all), and now this struct
is considered opaque.
For new implementations I recomend to hide struct definition in the
*.c and just use in the header:
typedef _MyStruct MyStruct;
This hides internal definition and forces the developer to use the
API. This way GObject Introspection will always make bindings to
modify struct fields as expected by the implementator and makes very
easy to automatically generate GIR files with the required API.
