use of eu.ggnet.dwoss.assembly.client.support.monitor.MonitorManager in project dwoss by gg-net.

the class DwOssApplication method start.

/**
 * Starting the Deutsche Warenwirtschaft Open Source application.
 * The startup happens through the following steps:
 * <ol>
 * <li>Parameter validation via <a href="https://jcommander.org/">JCommander</a>. The required and optional parametes are defined here
 * {@link ConnectionParameter}.</li>
 * <li>Setting the LAF for Swing components via {@link LafMenuManager#loadAndSetUserLaf() }</li>
 * <li>Displaying a placeholder main pane and the blocking login screen.
 * <ul>
 * <li>The login screen has no authentification system on visibility but the user can already type in his username and password.</li>
 * <li>The guardian is set later and only then an authentification will happen, even if the user has pressed return before.</li>
 * <li>A red/green circle in the ui displays the status of the guardian (red meaning not yet set).</li>
 * </ul>
 * </li>
 * <li>Initialize the client backend, remote connections, saft core, and preparing the main view by wrapping the javafx pane in a swing frame.
 * <ul>
 * <li>{@link #initSeContainer() }</li>
 * <li>{@link #initGlobalExceptionHandling() }</li>

 * </ul>
 * </li>
 * <li>Activating the authentification in the login screen by calling {@link LoginScreenController#setAndActivateGuardian(eu.ggnet.saft.experimental.auth.Guardian)
 * with the remote guardian</li>
 * <li>Start the polling of server progress {@link MonitorManager#startPolling() }</li>
