## Class DefaultEditorKit.DefaultKeyTypedAction

- java.lang.Object
- - javax.swing.AbstractAction
  - - javax.swing.text.TextAction
    - - javax.swing.text.DefaultEditorKit.DefaultKeyTypedAction

- All Implemented Interfaces:
    ActionListener, Serializable, Cloneable, EventListener, Action
  Enclosing class:
    DefaultEditorKit

      public static class DefaultEditorKit.DefaultKeyTypedAction
      extends TextAction

  The action that is executed by default if a key typed event is received and there is no keymap entry. There is a variation across different VM's in what gets sent as a key typed event, and this action tries to filter out the undesired events. This filters the control characters and those with the ALT modifier. It allows Control-Alt sequences through as these form legitimate unicode characters on some PC keyboards.

  If the event doesn't get filtered, it will try to insert content into the text editor. The content is fetched from the command string of the ActionEvent. The text entry is done through the `replaceSelection` method on the target text component. This is the action that will be fired for most text entry tasks.

  Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the `java.beans` package. Please see `XMLEncoder`.
