Using the widget builder : Mashup Center 2.0
The widget builder is a browser-based, easy-to-use tool that you can use to create custom widgets and share them with the community. This topic provides an overview of some of the tasks you can perform using the widget builder.
Configuring widgets : Mashup Center 2.0
When you configure widgets, you set public properties that define the widget's characteristics. For example, you can configure widgets to point to a particular file or feed URL so that it knows from where to pull data.
Managing widgets in the palette : Mashup Center 2.0
Mashup Center provides a palette with a default set of categories and widgets. You can make changes to the default palette to create a more personalized workspace. For example, you can add and remove widgets, add new categories, customize widgets, and more. You can drag widgets directly from the palette to your pages.
Wiring widgets : Mashup Center 2.0
When you wire two widgets on a mashup page, you essentially introduce the widgets to each other and tell them how to communicate. The widgets communicate by passing event data (often called a payload).
Working with payload types : Mashup Center 2.0
When you wire widgets together, you create the communication line that allows data to pass from one widget to another. This data is defined by the event name, the payload (the actual content), and the payload type.
Hiding widgets on the mashup page : Mashup Center 2.0
Sometimes you will want to add widgets to your mashup application but not display them on the page. For example, perhaps you simply need to convert Celsius to Fahrenheit in a data string, or you just need to transform some data using the Data Editor
, or Regular Expression
widgets. You will need to add those widgets to your page, but you probably do not want them to display in view mode. In this case, you can easily hide the widgets in the hidden widgets corral.
Marking widgets as nontrusted : Mashup Center 2.0
As a business user, you can use the Mashup Center widget builder to create widgets and then flag them as non-trusted. Marking widgets as non-trusted is useful when your widget has the potential to cause a security risk to the host system, for example by sending malicious scripts that grab cookies or modify DOM nodes. By default, widgets that you create using the widget builder are trusted.
