In python a tree of namespaces is created on the filesystem using a folder for each namespace, and in that folder there is a file for each class (more or less). To implement the Efl namespace I must create a folder called Efl, and the Efl.Canvas namespace is a folder inside the Efl Folder: Efl (the namespace, a folder) -> Canvas (the namespace, a folder inside the Efl folder) -> Canvas (the class, a file inside the Efl folder) This is just not going to work in python. I can workaround lowering the namespaces as: efl (the namespace, a folder) -> canvas (the namespace, a folder inside the efl folder) -> Canvas (the class, a file inside the efl folder) This will work on linux, no idea if it will work on windoz... > > > > > > > To better understand what I'm speaking about please give a look at: > > http://www.gurumeditation.it/dokuwiki/doku.php?id=develop:api:start > > http://www.gurumeditation.it/dokuwiki/doku.php?id=develop:api:namespaces > > > > Those pages are automatically generated, are NOT python related, and > should > > serve as a reference for the UnifiedAPI work in progess, they provide a > > clean view of the current state of our new API. > > > > > > waiting for comments and ideas > > davemds > > ------------------------------------------------------------ > ------------------ > > Check out the vibrant tech community on one of the world's most > > engaging tech sites, Slashdot.org! http://sdm.link/slashdot > > _______________________________________________ > > enlightenment-devel mailing list > > enlightenment-devel@lists.sourceforge.net > > https://lists.sourceforge.net/lists/listinfo/enlightenment-devel > > ------------------------------------------------------------ > ------------------ > Check out the vibrant tech community on one of the world's most > engaging tech sites, Slashdot.org! http://sdm.link/slashdot > _______________________________________________ > enlightenment-devel mailing list > enlightenment-devel@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/enlightenment-devel > ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ enlightenment-devel mailing list enlightenment-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/enlightenment-devel
