public class Application
extends gnu.app.Application

X application.

A basic X application is expected to extend this class and call the constructor with its command-line arguments. See gnu/x11/test/Hello.java for an example.

To run an X application, the name of the X server to be connected to must be given. By default, the value is fetched from the environment variable $DISPLAY. Users can override this by specifying --display option. Simply java gnu.x11.test.Hello will display a window in the default X server.

Users can also specify --send-mode option. For instance, java gnu.x11.test.Hello --send-mode sync will display the same window but the protocol requests are sent synchronously. See Connection#send_mode and Connection#SEND_MODE_STRINGS for more info.

X server connection.

Note that this variable (X connection) should not be used before calling Application.about(java.lang.String, java.lang.String, java.lang.String, java.lang.String) since it is possible that users specify "--help" option and no connection is made at all.
