Hi, I've been digging and inspecting all the classes related to Morphic. But there's something that I don't happen to figure out. Morph has a method drawOn: aCanvas aCanvas fillRectangle: self bounds fillStyle: self fillStyle borderStyle: self borderStyle Which if it's not overridden by a subclass of Morph makes it possible to still instantiate a Morph -the classic blue rectangle. Now aCanvas is obviously an instance of FormCanvas or some other subclasses of Canvas. But the question is, where does Morph create such instance of FormCanvas? How does this work? I'm getting all wrong? I read the documentation available but I can't grasp it from what I have read. Thanks in advance for your help best Nacho ----- Nacho Smalltalker apprentice.
