\class QCopEnvelope qcopenvelope_qws.h
\brief The QCopEnvelope class encapsulates and sends QCop messages
over QCopChannels.
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.

If \a message has parameters, you must then use operator<<() to
