I rescued some of your changes and published a working slice. Now you should use the latest version of pharo in the future. Stef

Mark I'm trying to merge your changes but I wonder on which version you were working because you should use Pharo40.

Now, if you have an AthensCanvas (from the AthensWrapMorph) and your own Morph does not implement drawOnAthensCanvas, then Morph>>#drawOnAthensCanvas is called which just draws an rectangle from your Morphs bound. For example, put a PolygonMorph on an AthensWrapMorph. It is drawn as a rectangle, because PolygonMorph does not know (yet) how to draw itself with athens. If you have new a Morph that is just container of other Morphs than you don't need to change anything. Just make sure your toplevel Morph is wrapped by an AthensWrapMorph. But If you have a Morph, that subclasses another Morph that overrides drawOnAthensCanvas, you'll have to reimplent this as well. For example, MenuItemMorph subclasses StringMorph and StringMorph implements its own drawOnAthensCanvas. If you put a MenuMorph in a AthensWrapMorph it will be drawn like a plain StringMorph not like a MenuItemMorph (without icons and arrows for submenus etc). > One of the idea is that you have a wrappingMorph that convert the Morphic > to Athens drawing.

I would suggest: - build it on top of roassal / trachel, i.e. draw always with athens. - build it as Morphs and implement drawOnAthensCanvs if needed.

One of the idea is that you have a wrappingMorph that convert the Morphic to Athens drawing. This way you can use athens and still be in a non athens world, then we will switch to athens you will just have to unwrap your (athensihed morph). Now about the granularity question it depends, what I would do is to have one wrapper and be in a athens world. Did you check the trachel layer in Roassal? What would be good is that - you define drawOnAthensCanvas: for all the shapes you need and we integrate them into Pharo - like that slowly we will get ready to switch to Athens > Should AthensMorphWrap be around every morphic element or just the top > level? i.e. > CanvasMorph (owner of the surface) will have a single submorph > AthensMorphWrap which will then hold all the morphs (EllipsisMorph, > RectangleMorph, ...) which are being drawn on the canvas. I think so. This is what Roassal is doing. Please keep us aware of your progress and do not hesitate to ask questions and we are REALLY interested in your project. So if you have athens draw on method please send them to us. Stef > > Thanks, > Peter

drawing morphs with athens

by Peter UhnÃ¡k

Hello, I'm currently working on drawing engine (Ã la Squeak Connectors) as a part of school project and have a couple of questions about Morphs and Athens and would be grateful if someone could enlighten me. What is the difference between "Morph>>#drawOn:" and "Morph>>#drawOnAthensCanvas:" if I draw on AthensCairoSurface? Should I always use the latter or will there be switch to the former once everything is rendered using Athens? Should AthensMorphWrap be around every morphic element or just the top level? i.e. CanvasMorph (owner of the surface) will have a single submorph AthensMorphWrap which will then hold all the morphs (EllipsisMorph, RectangleMorph, ...) which are being drawn on the canvas. Thanks, Peter
