OlexContainerExample new open
Now, go to the edit menu, and select "Insert Object...":
You'll get a list of things you can embed. We've chosen WordPad here, as any installation of Windows should have access to that. You should see WordPad come up:
Now, enter some text and close WordPad without saving - the text will appear in the VA container:
Browse the class and take a look at how it's been set up - that should give you a starting point for doing this kind of thing in your own applications.

Using Smalltalk, you'll often run across the cascade syntax:
Here we have a small class with an instance variable, and the variable holds a collection. The use of #add: is followed by a cadcade (the semi-colon). What that does is ensure that the next message (#add: in this case) is sent back to the original receiver (the collection) rather than to the return object (#add: answers the object sent).
So in the example above, without the #yourself at the end, the last message send would answer 4 rather than the collection.
