For sending SMS we need to create message with XQMessage class. After creating message, send it using send() method of XQMessaging class. The following source code demostrate how to send SMS.
if (messaging.send(message) == XQMessaging::NoError)
msgBox.setText(tr("SMS was sent successfully"));
XQMessaging class emitt a signal messageReceived() when SMS is received, with reference of XQMessage class which has message body and sender information. so we need to catch that signal in your slots. The following source code demostrate how to receive SMS.
/* implement signal ans slots to listen all incoming message */
/* messaging is declared of type XQMessaging in header file.
* the slot receiveSMS() will get called on al incomming message */
connect(&messaging, SIGNAL(messageReceived(const XQMessage&)), this, SLOT(receiveSMS(const XQMessage&)));
/* receive incomming message */
void QtSMSOperation::receiveSMS(const XQMessage& message)
/* message.sender() contains the cell number of sender
* and message.body contain body part of message */
- The Code Example will show how to send and receive messages in Qt and is tested on Nokia 5800 XpressMusic.
