Class ToggleColumnAction

java.lang.Object
  javax.swing.AbstractAction
      de.mguennewig.pobjsearch.ToggleColumnAction

All Implemented Interfaces:

java.awt.event.ActionListener, java.io.Serializable, java.lang.Cloneable, java.util.EventListener, javax.swing.Action

public final class ToggleColumnAction
extends javax.swing.AbstractAction

Action to toggle the visibility of a table column.

The visibility is toggled by removing/adding it from/to the table column model.

This action is enabled by default unless it is associated to the last visible column to prevent the table header to become invisible.

Serializable

Instances of this action are only serializable if the column model and the column name instance are serializable. In most cases this should be the case as the column name object is normally a string and the default column model is serializable.
