This is a heavily simplified version of WorldState@drawWorld:submorphs:invalidAreasOn: . If you need a accurate idea of the message, look at the original code. This is just to show what messages are sent to the Morphs in the drawing stage.
WorldState@drawWorld: aWorld submorphs: submorphs invalidAreasOn: aCanvas
"Redraw the damaged areas of the given canvas and clear the damage list. Return a collection of the areas that
were redrawn."
"SOME DAMAGED RECTANGLE CALCULATIONS"
"Now paint from bottom to top, but using the reduced rectangles."
aWorld drawOn: aCanvas. "Draw the World (just the world morph(background), no submorphs, ) "
aCanvas fullDrawMorph: morph . "Draw a Morph"
Canvas@fullDrawMorph: sends -misty paths- Morph@fullDrawOn: which is (simplified)
self drawOn: aCanvas.
self drawSubmorphsOn: aCanvas.
self drawDropHighlightOn: aCanvas.
self drawMouseDownHighlightOn: aCanvas.
