Thanks, Adam. Can you speak to the part about assembling them in a component hierarchy? I realize the ease of using *Element calls on the ResponseWriter, but I'd like to see how it would be done if real Html* components were used.
All the best, Shawn -----Original Message----- From: Adam Winer [mailto:[EMAIL PROTECTED] Sent: Thursday, February 22, 2007 1:07 AM To: [email protected] Subject: Re: Layout components in custom renderers To use table layout, etc., you assemble all of them into one component hierarchy, and then call encodeAll() on the root. These are components where rendersChildren="true", so you can't just render them with encodeBegin()/encodeEnd(). But these components (all the ones we call "Html" instead of "Core") really don't abstract you very much from the underlying HTML. So, honestly, you might do just as well to write ResponseWriter rw = context.getResponseWriter(); rw.startElement("table", null); rw.startElement("tr", null); ... etc... -- Adam On 2/21/07, Bertrand, Shawn R <[EMAIL PROTECTED]> wrote: > Hi all, > > > > I'd like to use the Trinidad layout components (HtmlTableLayout, > HtmlRowLayout, and HtmlCellFormat) in a custom component I've developed, > but I'm not sure how to integrate each component of the table together. > I'm sure I'm missing something basic (like linking them in parent-child > relationships), so thanks for your help in clarifying this. > > > > I originally thought calling the encode methods would do the trick, but > output suggested that rows need to be linked to the table, and cells > need to be linked to the rows.
