Widgets are the pluggable user interface components that you use to define the functionality of your business spaces.
By itself, a widget typically has limited or specific capabilities. However, you can combine widgets to interact with each other to perform related tasks. Combined widgets are called a mashup. For example, you can have a widget that displays news items from an RSS feed and another widget that you can use to create tasks that you assign to someone. If you combine the two widgets onto one page, you have created a mashup in which you can see a news event and react to it by assigning someone to investigate whether the event might affect your business.
Widgets communicate with other widgets so that events in one widget affect the contents of a different widget. Widgets communitcate by publishing and handling events.
Business Space provides a widget palette that contains categories of widgets you can use to configure the pages in your business spaces.
The following subtopics describe the events for the set of widgets available for Business Space powered by WebSphere:
