protected void configurePropertiesFromAction(Action action)


protected java.beans.PropertyChangeListener createActionPropertyChangeListener(Action action)


protected javax.swing.text.Document createDefaultModel()
          Creates the default model for this text field.

protected void fireActionPerformed()
          Sends an action event to all registered ActionListener objects.

javax.accessibility.AccessibleContext getAccessibleContext()
          Returns the accessible context associated with the JTextField.

Action getAction()


java.awt.event.ActionListener[] getActionListeners()
          Returns all registered ActionListener objects.

Action[] getActions()
          Returns the set of Actions that are commands for the editor.

int getColumns()
          Returns the number of columns of this text field.

protected int getColumnWidth()
          Returns the column width, which is the width of the character m for the font in use.

int getHorizontalAlignment()
