The header and footer classes

To manage page headers and footers, the printing framework also contains two additional subclasses of IlvPrintableObject: IlvHeader and IlvFooter. Although these two classes are subclasses of the IlvPrintableObject , you do not add them to the page like other printable objects. The header and footer are common to all pages of a document, and thus are set on the instance of the IlvDocument class.

Here are the methods of the class IlvPrintableDocument to set a header or a footer:

public void setFooter(IlvFooter footer)
public IlvFooter getFooter()

public void setHeader(IlvHeader header)
public IlvHeader getHeader()

The IlvHeader and IlvFooter classes are very similar. A header or footer is defined by three text sections. Each section can have a specified font.

Here is an example of a header:

Each of the three text sections of a header or footer can contain the text that you specify in the constructor of the object. For the header shown in Example of a header it would be:

new IlvHeader("7/12/02", "Printing demo", "Page 1"); 

Since the header and footer are defined on the document, you should not specify the page number as in the previous example. The IlvHeader and IlvFooter classes provide a certain number of keys that will be translated to values from the document, when the document is printed.

The list of keys that you can use is as follows:

To create the header in Example of a header, use the following new statement:

new IlvHeader(IlvHeader.DateKey, "Printing demo", "Page " + IlvHeader.PageKey)
