Re: [etoys-dev] [squeakland] how to hide ALL connectors to/from a specific node in the Connectors package?

First

#tellAllIncomingConnections: aMessageSelector and #tellAllOutgoingConnections: aMessageSelector

are just the first level connectors directly connected to the morph in question. Its one level deep.

You can look at Player>>tellAllSuccessors: aMessageSelector

If you change

self costume successors do:

to

self costume allSuccessors do:

you get a graph of all the morphs successors to the morph

This is IMO a bug. It says tellAllSuccessors but tells only the first node in the successor graph.

Same goes for tellAllPredecessors:

I'll try again:

I have 19 Connectors nodes showing in my project.

There are 19 x 18 connectors -a fully connected graph.

I want to be able to easily tell all connectors to hide using Etoys scripting. I already know how to do this with Squeak, but it isn't obvious at all how to make it work with etoys, despite the existence of a scripting option "tellAllIncomingConnections" and "tellAllOutgoingConnections"

I can't figure it out.

I've dropped down into the System browser and looked at the Smalltalk code for

#tellAllIncomingConnections: aMessageSelector

and

#tellAllOutgoingConnections: aMessageSelector

"Send the given message selector to all the players of the receiver's

costume's outgoing connections"

self costume outgoingConnections do:
    [:m |
        m playerRepresented ifNotNilDo:
            [:p | p performScriptIfCan: aMessageSelector]]

I've even tried putting ^#hide into the script.

Is this aspect of Connectors + Etoys broken or am I missing something?

I can specify a SPECIFIC Connector to hide, but I have potentially 19 x 18 or even 256 x 255 of them to work with, so obviously this isn't an option.

Do I have to go with my incredibly cumbersome code I worked out in my Squeak youtube tutorials and stick that into a script, instead?

Thanks.
