During the gocept sprint on z3c.form last week we found that the interface of pagelets (z3c.pagelet.interfaces.IPagelet) is a mere marker interface on top of IBrowserPage, which seems to me a bit thin.
For one, the implementation of pagelets makes use of the render and update methods. Since these methods are the ones to be customized when writing custom pagelets, they should be documented. While it would be easy enough to just add the methods to IPagelet (which has actually been done for render by now), I think IPagelet should really be an extension to zope.contentprovider.interfaces.IContentProvider in addition to IBrowserPage. It is already possible to use pagelets such as z3c.form.form.Form as content providers. While the pagelet implementation distinguishes between pagelet and pagelet renderer, only the latter being declared the content provider, this distinction seems to be made only in order for the content provider lookup to return the same pagelet instance that is the view. The renderer then only (sort of) forwards the pagelet's own content provider functionality, so the pagelet might as well be declared a content provider itself. Any thoughts, objections, ideas? -- Thomas _______________________________________________ Zope3-dev mailing list Zope3-dev@zope.org Unsub: http://mail.zope.org/mailman/options/zope3-dev/archive%40mail-archive.com
