I'm using Etoys and I want to change and objects "holder" What is the squeak code to embed it in a different object?

You have to detach the morph from its existing owner and then add it to the destination container. See grabMorph:from and attachMorph: methods for examples.

Also see senders of addMorph: and its variants addMorphFront:, addMorphBack: for more examples on how to embed morphs.

A Holder is essentially a PasteUpMorph with some options turned on. Other variants are Playfield, PartsBin etc.

Thanks Subbu.

I started looking at what you sent and poking around trying to figure out the code, then realized I could do it "the Etoys way" and put the morph back into its previous holder (which can vary and I store in a player variable). I wound up using a playfield include tile and replacing playfield with the variable used to store the original holder:

self getOrigHolder include: self.

Yep, that's the right way to do it in Etoys. In addition to moving the object, it also ensures it's in view, the holder's cursor gets updated etc.

If you were doing it in plain Morphic, you would do something like

newContainer addMorph: self

which automatically deletes self from its current container, but does not change the position etc.
