Class ReportDesignHandle

    java.lang.Object
      org.eclipse.birt.report.model.api.DesignElementHandle
          org.eclipse.birt.report.model.api.ModuleHandle
              org.eclipse.birt.report.model.api.ReportDesignHandle

All Implemented Interfaces:
  IModuleModel, org.eclipse.birt.report.model.elements.interfaces.IDesignElementModel, org.eclipse.birt.report.model.elements.interfaces.IReportDesignModel

    public class ReportDesignHandle

extends ModuleHandle
implements org.eclipse.birt.report.model.elements.interfaces.IReportDesignModel

Represents the overall report design. The report design defines a set of properties that describe the design as a whole like author, base and comments etc.

Besides properties, it also contains a variety of elements that make up the report. These include:

Content Item | Description
Code Modules | Global scripts that apply to the report as a whole.
Parameters | A list of Parameter elements that describe the data that the user can enter when running the report.
Data Sources | The connections used by the report.
Data Sets | Data sets defined in the design.
Color Palette | A set of custom color names as part of the design.
Styles | User-defined styles used to format elements in the report. Each style must have a unique name within the set of styles for this report.
Page Setup | The layout of the master pages within the report.
Components | Reusable report items defined in this design. Report items can extend these items. Defines a "private library" for this design.
Body | A list of the visual report content. Content is made up of one or more sections. A section is a report item that fills the width of the page. It can contain Text, Grid, List, Table, etc. elements
Scratch Pad | Temporary place to move report items while restructuring a report.
Translations | The list of externalized messages specifically for this report.
Images | A list of images embedded in this report.

Module allow to use the components defined in `Library`.

- User can call `ModuleHandle.includeLibrary(String, String)`to include one library.
- User can create one report item based on the one in library, and add it into design file.
- User can use style, data source, and data set, which are defined in library, in design file.

                          // Include one library

                          ReportDesignHandle designHandle = ...;
                          designHandle.includeLibrary( "libA.rptlibrary", "LibA" );
                          LibraryHandle libraryHandle = designHandle.getLibrary("LibA");

                          // Create one label based on the one in library

                          LabelHandle labelHandle = (LabelHandle) libraryHandle.findElement("companyNameLabel");
                          LabelHandle myLabelHandle = (LabelHandle) designHandle.getElementFactory().newElementFrom( labelHandle, "myLabel" );

                          // Add the new label into design file

                          designHandle.getBody().add(myLabelHandle);
