Class GridField

java.lang.Object
  org.compiere.model.GridField

All Implemented Interfaces:

Serializable, Evaluatee

public class GridField
extends Object
implements Serializable, Evaluatee

Grid Field Model.

Fields are a combination of AD_Field (the display attributes) and AD_Column (the storage attributes).

The Field maintains the current edited value. If the value is changed, it fire PropertyChange "FieldValue". If the background is changed the PropertyChange "FieldAttribute" is fired.
Usually editors listen to their fields.
