I wanted to ask if it's possible to extent an Athens surface. If it can't be done, because as far as I understand this can't be done in Cairo, is it possible to simulate it at least? Is it possible to stop #drawDuring: and build another surface, maybe? how large? is
AthensCairoSurface extent: 2000@2000
not works?
I think it is about resizing an existing Morph that is drawn with Athens Surface? I had problems with it and had the same question. But it works well with something like:
SomeSubclassOfMorph>>extent: aPoint |newExtent| newExtent := aPoint rounded. (bounds extent closeTo: newExtent) ifTrue: [^ self]. self changed. bounds := (bounds topLeft extent: newExtent). surface := AthensCairoSurface extent: newExtent. self layoutChanged. self changed.
Now Boids fly in a resizable sky :)
yes. this is the way. you cannot resize existing surface, but create a new one instead.
