Directive are usually declared in meta.zcml files. From there on you find your way to the schema where the fields should have useful titles and descriptions, and the implementation when necessary. The documentation of the z3c template directives should be more complete. Maybe you add a little information and guidelines to it. The declaration of the directives in the browser namespace ended up (at least for view and page) in zope.browserpage (factored out of zope.app.publisher). I learned the basics from and still sometimes use Phillip von Weitershausens book, even so it differs a lot from the current zope. Martins book should also be a good reference. Some basic stuff like views are not documented very well. ..Carsten > On Oct 13, 2:18 pm, derek <[email protected]> wrote: >> Thanks, that's all beginning to make more sense. >> >> On Oct 13, 1:32 pm, Carsten Senger <[email protected]> wrote: >> >> > Hi Derek, >> >> > --On Mittwoch, Oktober 13, 2010 06:35:47 -0700 derek >> >> > <[email protected]> wrote: >> > > Is it possible to override just a template for a widget, without >> > > creating a whole new Widget, WidgetFactory, Field and associated >> > > interfaces?
