HTML EMail
Locked
 
|
Hi All,
I am working on a Seaside server that as part of its function has to send EMail with HTML content. I have subclassed WAComponent to make an object that defines the HTML and used WARenderCanvas to render it. I am wondering if I should have subclassed WAPresenter instead of WAComponent. I'm not sure it matters much but would be interested in any comments. Lou ----------------------------------------------------------- Louis LaBrunda Keystone Software Corp.

At first glance, it doesn't sound like you need a Component or a
Presenter at all. You just want to use a Canvas to generate some HTML and you can do that from any object you want. By convention, you'd do this by implementing an object with a #renderOn: method but even that's not strictly necessary. In 2.9 you could subclass WAPainter. An exception to the above would be if you need to embed other Presenters within your rendering. Also, if you haven't found it already, you might want to look at Builder (you create one by calling the class-side #builder method on a Canvas). This should make getting a string of the HTML easy.

WAPresenter is preferable since it's not a "general" component and many component features won't work: callbacks, #updateRoot:, backtracking, ... It does not matter a big deal though, it's more a stylistic thing.

Thanks Julian and Philippe for your replies.
I do need to embed other Presenters within my rendering. So I guess Presenters are the way to go. I would like to know more about the Builder you mentioned below. Can I use it instead of WARenderCanvas? If so, can you please give me an example. Many thanks inadvance, Lou >At first glance, it doesn't sound like you need a Component or a >Presenter at all.

You use it *with* a Canvas. A Builder simply drives a Canvas (well,
any renderer) for you. It handles setting up the Document, the render context, etc. and provides a way to get at the resulting content. Look for senders of #builder in the image for a few examples.
