| <h3>Description</h3> |
| |
| <div class="section-text"> |
| Represents an extended item element. The extended report item |
| allows third-party developers to create report items that work within BIRT |
| virtually identically to BIRT-defined items. |
| |
| <p>Extended items can use the user-properties discussed above to define properties. |
| Extended items are defined in a Java plug-in that contributes behavior to the Eclipse |
| Report Developer, to the Factory and to the Presentation Engine. |
| |
| <p>The extended item can fully participate with the other BIRT extension facilities, |
| meaning that report developers can add properties and scripts to an extended item, |
| providing a very powerful way to create application-specific functionality. |
| An extended item is defined by a plug-in. The plug-in is specific to BIRT, |
| and is different from an Eclipse plug-in. Each item plug-in has four parts: |
| <ul> |
| <li>Design: handles the model that describes the report item. |
| <li>User Interface: the UI displayed for the item. This is in the form of an |
| Eclipse plug-in. |
| <li>Factory: how to gather the data for the extended item, and compute its |
| default size in the Factory. |
| <li>Presentation: how to render the extended item when rendering the report |
| to HTML, PDF or other formats. |
| </ul></div> |
