Class GridTab

java.lang.Object
  org.compiere.model.GridTab

All Implemented Interfaces:

Serializable, EventListener, DataStatusListener, Evaluatee

public class GridTab
extends Object
implements DataStatusListener, Evaluatee, Serializable

Tab Model. - a combination of AD_Tab (the display attributes) and AD_Table information.

The Tab owns also it's Table model and listens to data changes to update the Field values.

The Tab maintains the bound property: CurrentRow

  Event Hierarchies:
      - dataChanged (from MTable)
          - setCurrentRow
              - Update all Field Values

      - setValue
          - Update Field Value
          - Callout
