Re: [Pharo-dev] Convert to Athens
I'm facing some problems with AthensWrapMorph. Basically, when I add a morph, I can't change its position. It just stays in the top left. Whatever I try to do to change its position (self position: 100@100) does not work. Cheers, Jeff On Wed, Nov 20, 2013 at 5:04 PM, J.F. Rick s...@je77.com wrote: Thanks. It works.

Re: [Pharo-dev] Convert to Athens
Here's a piece of code to demonstrate the problem: AthensWrapMorph new extent: 300@300; addMorph: (Morph new position: 100@100; extent: 100@100; yourself); openInWorld. I think this should draw a blue square at 100@100. Instead, it draws a blue square at 0@0. What am I doing wrong? Cheers, Jeff On Wed, Dec 4, 2013 at 6:17 PM, J.F.

I changed the names and the evil rectangle of doom disappeared. this is recent changes. I chosen to namespace selectors. The former selectors should not be used and replaced by new ones (if they still there). I suspect you using outdated version + loaded recent version(s) of packages, going into desync between packages. It is recommended to always use published version of Athens and always load configuration(s). (2) Using the AthenWrapMorph, it seems that the bottom row of pixels is not rendered or clipped. I can stop this phenomenon by changing the createSurface method to have the extent be 0@1 bigger. While that works, it seems like there's a bug somewhere in AthensCairoSurface. I doubt it is in AthensCairoSurface. Most probably it is clipping issue. Need to be carefully checked. Changing the surface size is just workaround.

Do I have to explicitly tell Athens to rerender it? If so, how? I tried self render but that did not seem to help. No any equivalent. Updating UI is orthogonal to Athens. AthenWrapMorph sends drawOnAthensCanvas: to its submorphs, everything else is up to implementation.

Yes, there is AthensSceneView (read its class comment, its really easy to use) for transition , i implemented a special morph, AthensWrapMorph which wraps (as its name says) its children morphs and forces them to be rendered by athens (the child morphs will never receive #drawOn: but #drawOnAthensCanvas: instead ). Like that you can start using athens for current state of morphic and later, when whole World will be rendered by athens, you will no longer will need to use wrapper, so you will just throw it out from hierarchy without changing your existing code.

[Pharo-dev] Convert to Athens
Hi, I want to start using Athens for rendering. How do I get started? I've gone ahead and upgraded to the latest Pharo 3.0 and taken a look at the example classes. While that gives me some ideas about what the Athens canvas is capable of (impressive), I have an existing Morphic application that I want to redo with Athens rendering. I'm not sure how to begin doing that. I couldn't find a tutorial to get me started on doing conversion. Is there such a thing? It would be nice to have a morphic example (i.e., multiple morphs composed together all using Athens for rendering) shipped with the image.

Re: [Pharo-dev] Convert to Athens
Hello Athens is a vector graphics library, its not a GUI API. Athens will not give you buttons, menus, drop down lists and GUI elements. It will give you however the means to draw all those things and much more. I am actually making an Athens driven application myself , called Hyperion , a vector graphics editor and I hope also a designer that will allow you to make GUIs with Athens. But this project will take me a very long time. The best source right now for learning Athens is the Athens tutorial, you can find it in the smalltalkhub repo in the Athens-Tutorial package. It has 32 very useful examples which will give you a very good idea of what Athens can do. I will try also to contribute to Athens documentation in the near future , but for now I am very new to all this and these things take time. Also Igor which is the creator of Athens , always welcomes questions in this list and always replies ;) So don't be shy, ask away :) On Thu, Nov 14, 2013 at 6:39 PM, J.F.
