Thank you for your feedback
@Marcus I spend hours doing experiments with the font rendering, I think there must be a way to make it look better, because AFAIK there are other cairo based applications and the font rendering looks better. (maybe only linux?) Yes, the AthensTestDisplay is initialized with the current screen extent. We can reset that after the window changed (AthensTestDisplay reset). But this is only a test envionment, if we *ever* change the default morphic rendering backend to Athens, we have to develop a real athens world display workflow. (reinit athens on startup, provide a fallback if we move the image to a system without cairo...) 2015-01-31 10:33 GMT+01:00 Alain Plantec <alain.plan...@yahoo.com>: > super! > it just works fine, except the font. > I’ve also noticed that the mouse pointer is not drawn while dragging a > morph. > @Alain Yes the HandMorph is handled like any other Morph, it draws itself and after that it draws all its submorphs.

I will upload the changes in Athens-Morphic package to the Athens repository. But there are actually 5 different kinds of changes and I will group them as: athens morphic support (missing implementation for borderstyles, fillstyles, ) athens text support (athens based display scanner and some changes to the TextMorphs) athens drawOn (some more drawOnAthensCanvas methods (based on the two above) athens canvas wrapper ( the Athens based wrapper for (Morphic-)Canvas) athens drawOn with canvas wrapper ( other missing drawOnAthensCanvas methods, but those that use the CanvasWrapper for its implementation) And the AthensTestDisplay? I don't know, it is just for the testing, but we need something better. nicolai > thanks > Alain > > > Le 31 janv. 2015 à 09:48, Marcus Denker <marcus.den...@inria.fr> a écrit : > > Nice!
