This page has examples to help you get started with adding LADI and jackdbus support to your app.

= Level 1 app examples =
 * [source:/example-apps/level1.py Example level 1 app in Python]
 * [source:/example-apps/level1-qt.cpp Basic code to enable LADISH level 1 support to an event driven Qt (3/4) application]

= jackdbus examples =
== Qt/C++ ==
 
From qjackctl '''by Rui Nuno Capela'''. You need Qt >= 4.2 to use this example (DBus support was not there before).

This will check for jackdbus and if it is found will connect to the org.jackaudio service.

#!cpp

#include <QDBusConnection>

	//QDBusConnection dbusc = QDBusConnection::sessionBus(); -- default
	QDBusInterface dbusi(
		"org.jackaudio.service",	// Service
		"/org/jackaudio/Controller",	// Path
		"org.jackaudio.JackControl");	// Interface
		//dbusc);			// Connection

	if (dbusi.call("IsStarted").type() == QDBusMessage::ReplyMessage) {
		//
		// jackdbus is available and/or already started:
		// - use jackdbus control and configure interfaces...
		//
	} else {
		// QDBusMessage::ErrorMessage?
		//
		// jackdbus is not available, not started or not even installed:
		// - use classic jackd, business as usual...
