Adding inspector transmission node

[jordanmontt]

Currently there is two solutions for having the transmissions on the inspector

• Either you use StInspectorNode to wrap your data, but it very limited with the transmissions
• Either you create a presenter class and customize the transmissions. Bad side is that you need to create a class and for simple presenters is not convenient.

I was thinking on this the other day. So you are right, the blog post and StInspectorNode are not compatible.

One solution that I can think is to create a StInspectorTransmissionNode that manages the transmission. This can be a third option when you have a small presenter that you want to put in the inspector and you don't want to create a class but you want the power of transmissions.

This PR introduces the class StInspectorTransmissionNode that allows to the user to specify custom transmissions inside the Inspector in an easy way.

Let's take this code:

<inspectorPresentationOrder: 1 title: 'Demo'>
    | items |
    items := #( 1 2 3 4 5 6 7 8 ).

    ^ SpListPresenter new
        items: (items collect: [ :e |
            StInspectorTransmissionNode hostObject: e transmissionBlock: [ :theObject | theObject + 100 ] ]);
        display: [ :e | e hostObject ];
        yourself

This produces the inspector extension that add 100 when you click on a number

sorry for coming late to this, but an example in the class comment would be useful.
also, I do not like transmissionBlock: as a name :P
(I never liked the "type declaring names", transmissionAction: or just transmits: or similar are better names IMO.

Hello @estebanlm
I will add a new PR with your observations. Maybe tomorrow on the Pharo sprint
