public class About

extends javax.swing.JPanel

An "About" dialog box. This dialog box contains the application's title and some system informations (Java and OS version, free memory, image readers and writers, running threads, etc.). The application version can be fetched from a Manifest object, usually build from the file. This manifest should contains entries for , and values, as suggested in the Java tutorial. In addition to the above-cited standard entries, the class understand also an optional entry. This entry can contains the product date in the "yyyy-MM-dd HH:mm:ss" patter. If presents, this date will be localized according user's locale and appended to the version number.

Constructor Detail

About

public About()

Construct a new dialog box with the Geotools's logo.

About

public About(java.lang.Object logo,
             java.lang.Class application,
             java.lang.ThreadGroup tasks)

Constructs a new dialog box for the specified application class. This constructor uses the class loader for loading the manifest file. It also use the class package to find the right entry into the manifest.

Parameters:

logo - The application's logo. It may be a JComponent, an Icon object or an resource path (i.e. a file to be fetch in the classpath) as a String.

application - The application's class. Application name will be fetch from the manifest file ().

tasks - Group of running threads, or if there is none.

About

public About(java.lang.Object logo,
             java.util.jar.Attributes attributes,
             java.lang.ThreadGroup tasks)

Constructs a new dialog box from the specified manifest attributes.

Parameters:

logo - The application's logo. It may be a JComponent, an Icon object or an resource path (i.e. a file to be fetch in the classpath) as a String.

attributes - The manifest attributes containing application name and version number.

tasks - Group of running threads, or if there is none.

Method Detail

showDialog

public void showDialog(java.awt.Component owner)

Popups the dialog box and wait for the user. This method always invoke start() before showing the dialog, and stop() after disposing it.

start

protected void start()

Start a daemon thread updating dialog box information. Updated information include available memory and the list of running tasks. You must invoke the stop() method after (typically in a construct) in order to free resources. is not automatically invoked by the garbage collector.

stop

protected void stop()

Free any resources used by this dialog box. This method must be invoked after start() in order to free resources. is not automatically invoked by the garbage collector.

touch

public static void touch(java.util.jar.Attributes attributes)

Convenience method for setting the attributes to the current date.

Parameters:

attributes - Attributes in which setting the compilation date.

main

public static void main(java.lang.String[] args)

Display the default "About" dialog box. This method is usefull for testing the widget appareance and for checking system informations.

Parameters:

args - the command line arguments
