示例1: run

{
QDBusConnectionInterface* connection = QDBusConnection::sessionBus().interface();
if(connection->isServiceRegistered(KGET_DBUS_SERVICE)) {
// KGet is running. Make the call immediately.
showNewTransferDialog();
return;
}
// KGet is not running. Ask DBus to start it.
connection->startService(KGET_DBUS_SERVICE);
if(connection->lastError().type() != QDBusError::NoError) {
KNotification::event(KNotification::Error,
i18n("<p>KGet Runner could not communicate with KGet.</p><p style=\"font-size: small;\">Response from DBus:<br/>%1</p>", connection->lastError().message()),
KIcon("dialog-warning").pixmap(KIconLoader::SizeSmall)/*, 0, KNotification::Persistant*/);
return;
}
// Set a timer to make the call when KGet has been started.
// This might still fail if it takes too long to start KGet.
// For me, the 1000ms delay is mooooore than sufficient.
