How to send messages to an object.

Hi,
Suppose I do:
Morph new openInWorld

and then:
EllipseMorph new openInWorld

without referencing them to a variable.
How do I access those objects?
Since the only thing I know is that is a "a Morph(428605440)" and a "an EllipseMorph(448004096)"
If I want to Morph(428605440) addMorph: EllipseMorph(448004096)
How do I achieve this?
Because they are both object living in the system but I can not reference them.....
Thanks in advance

Morph new openInWorld inspect.
Morph new openInWorld explore.

or

Morph new openInWorld
right-click inspect, explore or debug

in the opened window, you can use the lower text pane to send messages to the object.

Two options:
1. (Unscalable hack) Identify them by a unique feature of their description e.g. "(World submorphs detect: [ :e | e color = Color blue ]) addMorph: (World submorphs detect: [ :e | e isKindOf: EllipseMorph ])"
2. Bring back a feature like that of MathMorphs [1, pg. 9], which had a revolutionary interface where, for each argument to a message, you drag an object token (a Morph) onto the message receiver, and then select the message via a context menu.

I've been playing around with this and other ideas in my LivingCode project. In the screencast at https://www.youtube.com/watch?v=ejQh6wkII2Y, you can see a rough proof of concept - creating two tokens for your two Morphs, and then supplying the ellipse's token as an argument for the other Morph.

Re: How to send messages to an object.

@Hernan
Sending a message to an object using the inspector allows me to do:
self addMoprh: EllipseMorph new.

But what I want is to add a morph to another morph that is already instantiated.
I want to reference the object that is somewhere in the memory an be able to manipulated even if I have not assigned it a reference | aMorph |.

@Sean
As I told you, your Self World is impressive. I see how easy is to do what I want in that Self World.
I will take a look at MathMorphs, I think I've tried to make it work in Pharo but had no success.

Thanks both of your for your answers
Best

Use the halos.

In Windows is Alt+Shift+Left click over your morph.

Then select the Menu halo (red) -> debug... -> explore morph

Yes, you can bring up an inspector/explorer on each morph, but the hiccup is how do you connect them i.e. send one as an argument to the other?

Re: How to send messages to an object.

I see! something like?

self addMorphCentered: (EllipseMorph allInstances detect: [ : i | i name = 'an EllipseMorph(485752832)' ])

Re: How to send messages to an object.

What if inspectors and workspaces were able to copy-paste object references?

When pasting, a new binding would be made with some automatic name.

I always wondered why this was not part of Morphic…

Re: How to send messages to an object.

Indeed, this is a little feature a proper object-oriented environment should not miss :)

Re: How to send messages to an object.

Yes, but please don't just limit it to UI things.

I want to be able to 'Copy an object' to an 'Object Clipboard' when I am on 'self' in an Inspector. And I want to be able to 'Paste an object' in a slot of an Inspector, or wherever that makes sense.

I always emulate this with a global, like XXX or ObjectClipboard, but it should be possible to do this without typing.

Re: How to send messages to an object.

If you want to do it as part of your application, maybe** look into sender and implementers of #acceptDroppingMorph:event:

cheers -ben

** I have no great experience with this. Just had a poke around for an answer.
