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.

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. A future release of Swing will provide support for long term persistence.
