- What is the easiest way to draw a graphical object (e.g., a line)?
Phillippe -- Andreas offers some nicely general solutions to your question. I'd like to add that Smalltalk has always supported turtle graphics which is probably the EASIEST way to draw a line:
Pen new turn: 30; go: 100
This may not be beautiful by modern standards. But it's handy when you want to add some debugging plot output to a complicated program. -- Ward
