Class ColumnDefinition

java.lang.Object
  javax.rad.model.ColumnDefinition

All Implemented Interfaces:

Serializable, Cloneable

public class ColumnDefinition
extends Object
implements Serializable, Cloneable

A ColumnDefinition is a description of the data type and other attributes of a table column.

Example:

 
 ColumnDefinition cdName = new ColumnDefinition("name");
 
 // set properties
 cdName.setWidth(10);
 cdName.setLabel("Name");
 cdName.setNull(true);
 cdName.setReadOnly(true);
 cdName.setWritable(false);
 
 // set RowDefinition;
 RowDefinition rdRowDefinition = new RowDefinition();
 cdName.setRowDefinition(rdRowDefinition);
