List (iText 5.5.13.1 API)

java.lang.Object
- com.itextpdf.text.List

All Implemented Interfaces:: Indentable, Element, IAccessibleElement, TextElementArray

Direct Known Subclasses:: GreekList, RomanList, ZapfDingbatsList, ZapfDingbatsNumberList

public class List
extends Object
implements TextElementArray, Indentable, IAccessibleElement

A List contains several ListItems.

Example 1:

 List list = new List(true, 20);
 list.add(new ListItem("First line"));
 list.add(new ListItem("The second line is longer to see what happens once the end of the line is reached. Will it start on a new line?"));
 list.add(new ListItem("Third line"));

The result of this code looks like this:

First line
The second line is longer to see what happens once the end of the line is reached. Will it start on a new line?
Third line

Example 2:

 List overview = new List(false, 10);
 overview.add(new ListItem("This is an item"));
 overview.add("This is another item");

The result of this code looks like this:

This is an item
This is another item
