[Newbies] smalltalk and squeak

[dimitris chloupis]

I am also very interested in this question. I can create a morph with drag and drop and inspect it , but i cant change its variables in any way. Also the System / Class browser you mention is only for class definition , and not giving access to instance objects . For example an instance object will have its own size and of course its own location , how can I access these variables of that specific object ? Is there is way to edit a specific object, access its variables and functions or even assign it to a variable by using only the IDE ?

Thank you for your suggestions.


I guess I'm thinking in terms of HyperCard. With HyperCard I
      could script a button, field, card, stack, etc. With Squeak, I
      can't figure out
      to change what the calculator’s buttons do. If had created the
      calculator with
      HyperCard, I could easily change how its buttons work. Just open
      them and there's
      the script.
 
I’ve tried using the Browser, but can't access the Smalltalk code for the calculator, whether I create it with Smalltalk in the Workspace or build it using Morphic. Still don't get it.

When I close the workspace the calculator still works, but what happens to the code? Where is it? If I open a viewer of one of the buttons and change the button's color, what happens to the code I started with? Where is it? How do I view it again?
