Cool Portlets in Dojo
Posted by Shane O'Sullivan on March 11, 2009
You can see a demo of it at http://www.skynet.ie/~sos/misc/dojo/dojox/widget/tests/test_PortletInGridContainer.html?theme=soria
A Portlet is similar to a dijit.TitlePane, in that it has a title bar, a content area, and is collapsible. However, it should also have the option of being configurable, perhaps using a dialog box or an expandable area. A nice example is the BBC website at http://bbc.co.uk, or the Google Portal http://www.google.com/ig.
Portlets are generally presented in a draggable grid, and a very cool new addition to Dojo is the dojox.layout.GridContainer, which provides this framework.
A number of types of Portlets and Setting widgets will be provided, hopefully in v1.4 (1.3 is in final beta, so this is too late for that).
- dojox.widget.Portlet – this is the basic Portlet, which provides a close button, a collapse button, and a settings button. All of these are optional.
- dojox.widget.FeedPortlet – this Portlet loads an external Atom or RSS feed and displays it as a list. Hovering over an item shows a dijit.Tooltip with a summary of the news story.
- dojox.widget.ExpandableFeedPortlet – similar to FeedPortlet, but instead of using tooltips, a toggle icon is used to show more or less of a news story.
- dojox.widget.PortletSettings – a widget that can be placed inside a Portlet to provide customizable settings for that widget.
- dojox.widget.PortletDialogSettings – like PortletSettings, but the configuration options are displayed in a dijit.Dialog.
- dojox.widget.PortletFeedSettings – provides one or more URLs to Atom or RSS feeds for a FeedPortlet to load.
These widgets offer pretty large set of functionality, which should be sufficient for the majority of peoples needs. However, this is still in active development, and if you have any ideas for cool additions or changes I could make, please let me know.
