All Implemented Interfaces:

Direct Known Subclasses:

JXErrorDialogExceptionHandler

public class MessagesDialogExceptionHandler
extends AbstractDialogExceptionHandler

Displays a message to the user which is fetched from the I18N files based on the class and superclasses of the throwable.

For example if an IllegalArgumentException is thrown, it will search for java.lang.IllegalArgumentException.caption and java.lang.IllegalArgumentException.description first, and if it cant find that it will try in order: java.lang.RuntimeException.caption/description, java.lang.Exception.caption/description and java.lang.Throwable.caption/description.

The exception message is passed as a parameter, but is idented and wrapped first. Note for the repacing of {0} to work in a property file double quotes(") need to be escaped (\") and that single quotes (') should be avoided (escaping doesn't seem to work).
