MessaggioHi Michele,
there are two ways for doing it.
Either by creating a scripted operator from script, in wich case you'll use the
"AddPortGroup" method wich recieve as arguments "Min" and "Max".
Those arguments indicate the minimum/maximum items that can be connected for a
valid connection.
If you use 0 for min and a big number for max, you will create an optional port
group meaning that at operator creation time there is no need for something to
be connected, but you can add as many items ( up to the max limit ) as you want
, and remove items from the group down to none, without deleting the operator.
Either by editing an operator SPDL, and add in a group description:
Min = 0;
Max = Infinite;
for instance.
Once you've done this, the way you organize your 'group' of connected items is
up to you, and has nothing to do with the way the portgroup is defined.
If you use a Group in your scene, you will have to synchornize manualy the
members of the group and the connected item in the operator portgroup.
May be add an 'Update' button in your Operator PPG wich would call a Command,
updating the portgroup connections regarding to some predifined Group or even a
connected Group so you can query both the Group content and the PortGroup
content directly and synchronize them.
Hope this helps.

Subject: Scripted operators with N input connections
Hi, I need to plug a number of input objects into a scripted operator; the
number of these objects can be increased of decreased.
I've tried doing this with a group, but I cannot access its members via the
.members property via scops.
Maybe someone already did something like this before and could help me.
Thanks
Michele
