[jboss-dev-forums] [Design of JBoss Portal] - Re: Layout System

[PMN]

Happy to see this is not about using a technology but defining the concept.

Layout is at page level for application developper who wants to control the page rendition.

JBP 2.6 already uses layout and an astute to change layout when maximizing a window.
Portlet writes to windows and windows have region and index in a region.

No one else than the application developper knows what rendition he wants, it could be a grid with column and row, or it could be a temporal presentation with animation, audio. So choosing a region and passing parameters is the minimum to offer and that's probably enough to keep it lighweighted.

So if this is about controlling page rendition, portlet should continue to write to windows and a layout service should allow to change layout at page level, assign region and parameters at window level and finally define a region renderer to render windows associated to a given region.
