Class SwingFile

java.lang.Object
  |
  +--multex.demo.SwingFile

All Implemented Interfaces:

java.awt.event.ActionListener, java.util.EventListener

public class SwingFile

extends java.lang.Object

implements java.awt.event.ActionListener

Copies or moves a file, see methods File.copy(String,String) and File.move(String,String). Serves as a demonstration for reporting an exception which comes from a lower tier in the Swing user interface. Look as first example the command line file handling File, and as second example the AWT interface for file handling AwtFile. Each exception occurring in an ActionListener of the user interface is reported by calling

    multex.Swing.report(ownerFrame, exception);

Further description of the contents of the appearing message dialog see class AwtFile. The complete exception reports looks like:

File input could not be copied to output
CAUSE: java.io.FileNotFoundException: input (Das System kann die angegebene Datei nicht finden)
