purge of graphics objects

Hello,

Sometimes the size of a project does not reduce after the deletion of a graphic object.
How can I purge definitively the space of this object?

If the object is truly freed and no references anywhere in your code or
browsing tools, you can force a full garbage collection with:
Smalltalk garbageCollect.

See WorldMenu->help for a quick way to check vm statistics or space left.

Are you using the Etoys image or some other images? And you are
concerned about the resulting .pr file size, right?

In a fairly recent Etoys image, if there is no reference to the
object (via scripts or variables), it should usually work fine. The
definitive way is a bit technical and laborious...

Re: purge of graphics objects

Thanks a lot all,

Yes, an etoys image version.
Yes, I mean about the size of the pr (I have an "space is low" error now).
The (only?) trash is empty and the objects I want to destroy don't appear listed with:
"Imports default viewImages" neither "ScriptingSystem inspectFormDictionary" (I knew them),
but I'm not sure about references, I haven't here the project, of course it could be the reason. I will look for it.
But some questions:
I thought both dictionarys live inside the image file; any project can use it anyway really?
Yoshiki, how much technical and laborious is that method (if I do not get the purge anyway)? Is it a very exceptional situation? I mean the problem with this pr is really unusual?

thanks a lot!

Hi, Antonio,

One thing to try is "attempt misc repairs," found in the "authoring
tools" menu. In some images you may need to have the eToyFriendly
preference turned off to see this item.

And if you have a project that remains inexplicably bloated, please
email it privately to one or more of the usual Etoys developers, and
we'll be happy to have a look and see what we can find.

It is not that unusual unfortunately. And, here is an abbreviated
steps to take:

- Turn off eToyFriendly preference.
- open a workspace from the world menu.
- Say, if you know the class of the graphical object, type:

TheClassName allInstances

and press Cmd-i to get the inspector.

- Look toward the end of list (perhaps), and find one instance you
think it should be reclaimed already.
- Select the instance, and from the context-menu, and select perhaps
"explore pointers" (or my favorite is "objects pointing to this
value" as it is "leaner").
- In the pointer explorer which shows the objects pointing to the
graphical object, or the inspector, repeat the cycle to understand
the graph of objects around it, and think which other object(s)
is/are the root of cause.
