public class PEFileChooser
extends JFileChooser

A factory that produces and caches frequently accessed JFileChooser's.

JFileChooser's get instanciated on first call, and are then cached for better efficiency. As a side-effect, the last accessed directory is kept in memory, unless a call to configure(Properties) is made, which reinit the file chooser's.

Method Detail

getFileName

public static String getFileName(int chooserType,
                                 String contentTypeClassName)
Opens (and possibly inits on first call) a JFileChooser, the type of which is specified by one of the hereabove constants. If this is the first time a particular file chooser is accessed, it's created using, either the default settings, or the settings set by the last call to configure(Properties).

Parameters:
chooserType - allows to initialize the file chooser to be opened.
Returns:
the selected file ; null if a cancel action occured at any time.

configure

public static void configure(Properties preferences)
Configure the default directory for the static JFileChooser's from the given Properties object, using the following key/value pairs :
Then reinits the static JFileChooser so that they'll reflect the new preferences next time they're called.

Should be called on start-up, then each time preferences change.


store

public static void store(Properties preferences)
Store the current file and fragment directories to the given Properties object
