QCop messages allow applications to communicate with each other. These messages are sent using QCopEnvelope, and received by connecting to a QCopChannel. To send a message, use the following protocol: \code QCopEnvelope e(channelname, messagename); e << parameter1 << parameter2 << ...; \endcode For messages without parameters, simply use: \code QCopEnvelope e(channelname, messagename); \endcode (Do not try to simplify this further as it may confuse some compilers.) The \c{channelname} of channels within Qtopia all start with "QPE/". The \c{messagename} is a function identifier followed by a list of types in parentheses. There is no whitespace in the message name. To receive a message, you will generally just use your application's predefined QPE/Application/\e{appname} channel (see QPEApplication::appMessage()), but you can make another channel and connect it to a slot like this: \code myChannel = new QCopChannel( "QPE/FooBar", this ); - connect( myChannel, SIGNAL(received(const QCString &, const QByteArray &)), - this, SLOT(fooBarMessage( const QCString &, const QByteArray &)) ); + connect( myChannel, SIGNAL(received(const QCString&,const QByteArray&)), + this, SLOT(fooBarMessage(const QCString&,const QByteArray&)) ); \endcode See also, the \link qcop.html list of Qtopia messages\endlink. */ /*! Constructs a QCopEnvelope that will write \a message to \a channel. If \a message has parameters, you must then use operator<<() to add these parameters to the envelope. */ QCopEnvelope::QCopEnvelope( const QCString& channel, const QCString& message ) : QDataStream(new QBuffer), ch(channel), msg(message) { device()->open(IO_WriteOnly); } /*! Writes the message and then destroys the QCopEnvelope. */ QCopEnvelope::~QCopEnvelope() { QByteArray data = ((QBuffer*)device())->buffer(); const int pref=16; if ( qstrncmp(ch.data(),"QPE/Application/",pref)==0 ) { QString qcopfn("/tmp/qcop-msg-"); qcopfn += ch.mid(pref); QFile qcopfile(qcopfn); if ( qcopfile.open(IO_WriteOnly | IO_Append) ) { #ifndef Q_OS_WIN32 if(flock(qcopfile.handle(), LOCK_EX)) { /* some error occurred */ qWarning(QString("Failed to obtain file lock on %1 (%2)") .arg(qcopfn).arg( errno )); } #endif { QDataStream ds(&qcopfile); ds << ch << msg << data; qcopfile.flush(); #ifndef Q_OS_WIN32 flock(qcopfile.handle(), LOCK_UN); #endif qcopfile.close(); } QByteArray b; |
