+ \class TQDns qdns.h
+ \brief The TQDns class provides asynchronous DNS lookups.
+\if defined(commercial)
+ It is part of the <a href="commercialeditions.html">TQt Enterprise Edition</a>.
+\endif
+
+ \module network
+ \ingroup io
+
+ Both Windows and Unix provide synchronous DNS lookups; Windows
+ provides some asynchronous support too. At the time of writing
+ neither operating system provides asynchronous support for
+ anything other than hostname-to-address mapping.
+
+ TQDns rectifies this shortcoming, by providing asynchronous caching
+ lookups for the record types that we expect modern GUI
+ applications to need in the near future.
+
+ The class is \e not straightforward to use (although it is much
+ simpler than the native APIs); TQSocket provides much easier to use
+ TCP connection facilities. The aim of TQDns is to provide a correct
+ and small API to the DNS and nothing more. (We use "correctness"
+ to mean that the DNS information is correctly cached, and
+ correctly timed out.)
+
+ The API comprises a constructor, functions to set the DNS node
+ (the domain in DNS terminology) and record type (setLabel() and
+ setRecordType()), the corresponding get functions, an isWorking()
+ function to determine whether TQDns is working or reading, a
+ resultsReady() signal and query functions for the result.
+
+ There is one query function for each RecordType, namely
+ addresses(), mailServers(), servers(), hostNames() and texts().
+ There are also two generic query functions: canonicalName()
+ returns the name you'll presumably end up using (the exact meaning
+ of this depends on the record type) and qualifiedNames() returns a
+ list of the fully qualified names label() maps to.

+/*!
+ \class TQFtp qftp.h
+ \brief The TQFtp class provides an implementation of the FTP protocol.
+\if defined(commercial)
+ It is part of the <a href="commercialeditions.html">TQt Enterprise Edition</a>.
+\endif
+
+ \ingroup io
+ \module network
+
+ This class provides two different interfaces: one is the
+ TQNetworkProtocol interface that allows you to use FTP through the
+ TQUrlOperator abstraction. The other is a direct interface to FTP
+ that gives you lower-level access to the FTP protocol for finer
+ control. Using the direct interface you can also execute arbitrary
+ FTP commands.
+
+ Don't mix the two interfaces, since the behavior is not
+ well-defined.
+
+ If you want to use TQFtp with the TQNetworkProtocol interface, you
+ do not use it directly, but rather through a TQUrlOperator, for
+ example:
+
+ \code
+ TQUrlOperator op( "ftp://ftp.trolltech.com" );
+ op.listChildren(); // Asks the server to provide a directory listing
+ \endcode
+
+ This code will only work if the TQFtp class is registered; to
+ register the class, you must call qInitNetworkProtocols() before
+ using a TQUrlOperator with TQFtp.
+
+ The rest of this descrption describes the direct interface to FTP.
+
+ The class works asynchronously, so there are no blocking
+ functions. If an operation cannot be executed immediately, the
+ function will still return straight away and the operation will be
+ scheduled for later execution. The results of scheduled operations
+ are reported via signals. This approach depends on the event loop
+ being in operation.
+
+ The operations that can be scheduled (they are called "commands"
+ in the rest of the documentation) are the following:
+ connectToHost(), login(), close(), list(), cd(), get(), put(),
+ remove(), mkdir(), rmdir(), rename() and rawCommand().
+
+ All of these commands return a unique identifier that allows you
+ to keep track of the command that is currently being executed.
+ When the execution of a command starts, the commandStarted()
+ signal with the command's identifier is emitted. When the command
+ is finished, the commandFinished() signal is emitted with the
+ command's identifier and a bool that indicates whether the command
+ finished with an error.
+
+ In some cases, you might want to execute a sequence of commands,
+ e.g. if you want to connect and login to a FTP server. This is
+ simply achieved:
+
+ \code
+ TQFtp *ftp = new TQFtp( this ); // this is an optional TQObject parent
+ ftp->connectToHost( "ftp.trolltech.com" );
+ ftp->login();
+ \endcode
+
+ In this case two FTP commands have been scheduled. When the last
+ scheduled command has finished, a done() signal is emitted with
+ a bool argument that tells you whether the sequence finished with
+ an error.
+
+ If an error occurs during the execution of one of the commands in
+ a sequence of commands, all the pending commands (i.e. scheduled,
+ but not yet executed commands) are cleared and no signals are
+ emitted for them.
+
+ Some commands, e.g. list(), emit additional signals to report
+ their results.
+
+ Example: If you want to download the INSTALL file from Trolltech's
+ FTP server, you would write this:
+
+ \code
+ ftp->connectToHost( "ftp.trolltech.com" ); // id == 1
+ ftp->login(); // id == 2
+ ftp->cd( "qt" ); // id == 3
+ ftp->get( "INSTALL" ); // id == 4
+ ftp->close(); // id == 5
+ \endcode
+
+ For this example the following sequence of signals is emitted
+ (with small variations, depending on network traffic, etc.):
+
+ \code
+ start( 1 )
+ stateChanged( HostLookup )
+ stateChanged( Connecting )
+ stateChanged( Connected )
+ finished( 1, FALSE )
+
+ start( 2 )
+ stateChanged( LoggedIn )
+ finished( 2, FALSE )
+
+ start( 3 )
+ finished( 3, FALSE )
+
+ start( 4 )
+ dataTransferProgress( 0, 3798 )
+ dataTransferProgress( 2896, 3798 )
+ readyRead()
+ dataTransferProgress( 3798, 3798 )
+ readyRead()
+ finished( 4, FALSE )
+
+ start( 5 )
+ stateChanged( Closing )
+ stateChanged( Unconnected )
+ finished( 5, FALSE )
+
+ done( FALSE )
+ \endcode
+
+ The dataTransferProgress() signal in the above example is useful
+ if you want to show a \link TQProgressBar progressbar \endlink to
+ inform the user about the progress of the download. The
+ readyRead() signal tells you that there is data ready to be read.
+ The amount of data can be queried then with the bytesAvailable()
+ function and it can be read with the readBlock() or readAll()
+ function.
+
+ If the login fails for the above example, the signals would look
+ like this:
+
+ \code
+ start( 1 )
+ stateChanged( HostLookup )
+ stateChanged( Connecting )
+ stateChanged( Connected )
+ finished( 1, FALSE )
+
+ start( 2 )
+ finished( 2, TRUE )
+
+ done( TRUE )
+ \endcode
+
+ You can then get details about the error with the error() and
+ errorString() functions.
+
+ The functions currentId() and currentCommand() provide more
+ information about the currently executing command.
+
+ The functions hasPendingCommands() and clearPendingCommands()
+ allow you to query and clear the list of pending commands.
+
+ The safest and easiest way to use the FTP protocol is to use
+ TQUrlOperator() or the FTP commands described above. If you are an
+ experienced network programmer and want to have complete control
+ you can use rawCommand() to execute arbitrary FTP commands.

+ \class TQHttpHeader qhttp.h
+ \brief The TQHttpHeader class contains header information for HTTP.
+\if defined(commercial)
+ It is part of the <a href="commercialeditions.html">TQt Enterprise Edition</a>.
+\endif
+
+ \ingroup io
+ \module network
+
+ In most cases you should use the more specialized derivatives of
+ this class, TQHttpResponseHeader and TQHttpRequestHeader, rather
+ than directly using TQHttpHeader.
+
+ TQHttpHeader provides the HTTP header fields. A HTTP header field
+ consists of a name followed by a colon, a single space, and the
+ field value. (See RFC 1945.) Field names are case-insensitive. A
+ typical header field looks like this:
+ \code
+ content-type: text/html
+ \endcode
+
+ In the API the header field name is called the "key" and the
+ content is called the "value". You can get and set a header
+ field's value by using its key with value() and setValue(), e.g.
+ \code
+ header.setValue( "content-type", "text/html" );
+ TQString contentType = header.value( "content-type" );
+ \endcode
+
+ Some fields are so common that getters and setters are provided
+ for them as a convenient alternative to using \l value() and
+ \l setValue(), e.g. contentLength() and contentType(),
+ setContentLength() and setContentType().
+
+ Each header key has a \e single value associated with it. If you
+ set the value for a key which already exists the previous value
+ will be discarded.

+ \class TQHttp qhttp.h
+ \brief The TQHttp class provides an implementation of the HTTP protocol.
+\if defined(commercial)
+ It is part of the <a href="commercialeditions.html">TQt Enterprise Edition</a>.
+\endif
+
+ \ingroup io
+ \module network
+
+ This class provides two different interfaces: one is the
+ TQNetworkProtocol interface that allows you to use HTTP through the
+ TQUrlOperator abstraction. The other is a direct interface to HTTP
+ that allows you to have more control over the requests and that
+ allows you to access the response header fields.
+
+ Don't mix the two interfaces, since the behavior is not
+ well-defined.
+
+ If you want to use TQHttp with the TQNetworkProtocol interface, you
+ do not use it directly, but rather through a TQUrlOperator, for
+ example:
+
+ \code
+ TQUrlOperator op( "http://www.trolltech.com" );
+ op.get( "index.html" );
+ \endcode
+
+ This code will only work if the TQHttp class is registered; to
+ register the class, you must call qInitNetworkProtocols() before
+ using a TQUrlOperator with HTTP.
+
+ The TQNetworkProtocol interface for HTTP only supports the
+ operations operationGet() and operationPut(), i.e.
+ TQUrlOperator::get() and TQUrlOperator::put(), if you use it with a
+ TQUrlOperator.
+
+ The rest of this descrption describes the direct interface to
+ HTTP.
+
+ The class works asynchronously, so there are no blocking
+ functions. If an operation cannot be executed immediately, the
+ function will still return straight away and the operation will be
+ scheduled for later execution. The results of scheduled operations
+ are reported via signals. This approach depends on the event loop
+ being in operation.
+
+ The operations that can be scheduled (they are called "requests"
+ in the rest of the documentation) are the following: setHost(),
+ get(), post(), head() and request().
+
+ All of these requests return a unique identifier that allows you
+ to keep track of the request that is currently executed. When the
+ execution of a request starts, the requestStarted() signal with
+ the identifier is emitted and when the request is finished, the
+ requestFinished() signal is emitted with the identifier and a bool
+ that indicates if the request finished with an error.
+
+ To make an HTTP request you must set up suitable HTTP headers. The
+ following example demonstrates, how to request the main HTML page
+ from the Trolltech home page (i.e. the URL
+ http://www.trolltech.com/index.html):
+
+ \code
+ TQHttpRequestHeader header( "GET", "/index.html" );
+ header.setValue( "Host", "www.trolltech.com" );
+ http->setHost( "www.trolltech.com" );
+ http->request( header );
+ \endcode
+
+ For the common HTTP requests \c GET, \c POST and \c HEAD, TQHttp
+ provides the convenience functions get(), post() and head(). They
+ already use a reasonable header and if you don't have to set
+ special header fields, they are easier to use. The above example
+ can also be written as:
+
+ \code
+ http->setHost( "www.trolltech.com" ); // id == 1
+ http->get( "/index.html" ); // id == 2
+ \endcode
+
+ For this example the following sequence of signals is emitted
+ (with small variations, depending on network traffic, etc.):
+
+ \code
+ requestStarted( 1 )
+ requestFinished( 1, FALSE )
+
+ requestStarted( 2 )
+ stateChanged( Connecting )
+ stateChanged( Sending )
+ dataSendProgress( 77, 77 )
+ stateChanged( Reading )
+ responseHeaderReceived( responseheader )
+ dataReadProgress( 5388, 0 )
+ readyRead( responseheader )
+ dataReadProgress( 18300, 0 )
+ readyRead( responseheader )
+ stateChanged( Connected )
+ requestFinished( 2, FALSE )
+
+ done( FALSE )
+
+ stateChanged( Closing )
+ stateChanged( Unconnected )
+ \endcode
+
+ The dataSendProgress() and dataReadProgress() signals in the above
+ example are useful if you want to show a \link TQProgressBar
+ progressbar\endlink to inform the user about the progress of the
+ download. The second argument is the total size of data. In
+ certain cases it is not possible to know the total amount in
+ advance, in which case the second argument is 0. (If you connect
+ to a TQProgressBar a total of 0 results in a busy indicator.)
+
+ When the response header is read, it is reported with the
+ responseHeaderReceived() signal.
+
+ The readyRead() signal tells you that there is data ready to be
+ read. The amount of data can then be queried with the
+ bytesAvailable() function and it can be read with the readBlock()
+ or readAll() functions.
+
+ If an error occurs during the execution of one of the commands in
+ a sequence of commands, all the pending commands (i.e. scheduled,
+ but not yet executed commands) are cleared and no signals are
+ emitted for them.
+
+ For example, if you have the following sequence of reqeusts
+
+ \code
+ http->setHost( "www.foo.bar" ); // id == 1
+ http->get( "/index.html" ); // id == 2
+ http->post( "register.html", data ); // id == 3
+ \endcode
+
+ and the get() request fails because the host lookup fails, then
+ the post() request is never executed and the signals would look
+ like this:
+
+ \code
+ requestStarted( 1 )
+ requestFinished( 1, FALSE )
+
+ requestStarted( 2 )
+ stateChanged( HostLookup )
+ requestFinished( 2, TRUE )
+
+ done( TRUE )
+
+ stateChanged( Unconnected )
+ \endcode
+
+ You can then get details about the error with the error() and
+ errorString() functions. Note that only unexpected behaviour, like
+ network failure is considered as an error. If the server response
+ contains an error status, like a 404 response, this is reported as
+ a normal response case. So you should always check the \link
+ TQHttpResponseHeader::statusCode() status code \endlink of the
+ response header.
+
+ The functions currentId() and currentRequest() provide more
+ information about the currently executing request.
+
+ The functions hasPendingRequests() and clearPendingRequests()
+ allow you to query and clear the list of pending requests.

+ Perhaps this private functionality needs to be refactored.
+
+ Comment from Robert D Gatlin (Intel):
+
+ It would be nice to have the functionality inherent in TQSocket available
+ as a separate class as a standard part of the TQt library, something along
+ the line of:
+
+ class TQByteBuffer : public TQIODevice { ... }
+
+ The same class could/would be used within TQSocket for the Read/Write
+ buffers.
+
+ The above class could be used in the following way(s):
+
+ buffer.open( IO_WriteOnly | IO_Append );
+ buffer.writeBlock( a ); // a = TQByteArray
+ buffer.close();
+
+ TQByteArray b;
+ b.resize( buffer.size() );
+ buffer.open( IO_ReadOnly );
+ buffer.readBlock( b.data(), b.size() );
+ buffer.close();
+
+ But would also be useable with TQDataStream (via TQIODevice) with:
+
+ buffer.open( IO_WriteOnly | IO_Append );
+ TQDataStream is( &buffer );
+ is << 100;
+ buffer.close();
+
+ buffer.open( IO_ReadOnly );
+ TQDataStream os( &buffer );
+ Q_UINT32 x;
+ os >> x;
+ buffer.close();
+
+ The real usefulness is with any situations where data (TQByteArray) arrives
+ incrementally (as in TQSocket and filter case above).
+
+ I tried using TQBuffer, but TQBuffer does not trim bytes from the front of
+ the buffer in cases like:
+
+ TQBuffer buf;
+ buf.open( IO_ReadOnly );
+ TQDataStream ds( &buf );
+ Q_INT32 x;
+ ds >> x;
+ buf.close();
+
+ In the above case, buf.size() will be identical before and after the
+ operation with TQDataStream. Based on the implementation of TQBuffer, it
+ does not appear well suited for this kind of operation.

+ \class TQSocket qsocket.h
+ \brief The TQSocket class provides a buffered TCP connection.
+\if defined(commercial)
+ It is part of the <a href="commercialeditions.html">TQt Enterprise Edition</a>.
+\endif
+
+ \ingroup io
+ \module network
+
+ It provides a totally non-blocking TQIODevice, and modifies and
+ extends the API of TQIODevice with socket-specific code.
+
+ Note that a TQApplication must have been constructed before this
+ class can be used.
+
+ The functions you're likely to call most are connectToHost(),
+ bytesAvailable(), canReadLine() and the ones it inherits from
+ TQIODevice.
+
+ connectToHost() is the most-used function. As its name implies,
+ it opens a connection to a named host.
+
+ Most network protocols are either packet-oriented or
+ line-oriented. canReadLine() indicates whether a connection
+ contains an entire unread line or not, and bytesAvailable()
+ returns the number of bytes available for reading.
+
+ The signals error(), connected(), readyRead() and
+ connectionClosed() inform you of the progress of the connection.
+ There are also some less commonly used signals. hostFound() is
+ emitted when connectToHost() has finished its DNS lookup and is
+ starting its TCP connection. delayedCloseFinished() is emitted
+ when close() succeeds. bytesWritten() is emitted when TQSocket
+ moves data from its "to be written" queue into the TCP
+ implementation.
+
+ There are several access functions for the socket: state() returns
+ whether the object is idle, is doing a DNS lookup, is connecting,
+ has an operational connection, etc. address() and port() return
+ the IP address and port used for the connection. The peerAddress()
+ and peerPort() functions return the IP address and port used by
+ the peer, and peerName() returns the name of the peer (normally
+ the name that was passed to connectToHost()). socketDevice()
+ returns a pointer to the TQSocketDevice used for this socket.
+
+ TQSocket inherits TQIODevice, and reimplements some functions. In
+ general, you can treat it as a TQIODevice for writing, and mostly
+ also for reading. The match isn't perfect, since the TQIODevice
+ API is designed for devices that are controlled by the same
+ machine, and an asynchronous peer-to-peer network connection isn't
+ tquite like that. For example, there is nothing that matches
+ TQIODevice::size() exactly. The documentation for open(), close(),
+ flush(), size(), at(), atEnd(), readBlock(), writeBlock(),
+ getch(), putch(), ungetch() and readLine() describes the
+ differences in detail.
+
+ \warning TQSocket is not suitable for use in threads. If you need
+ to uses sockets in threads use the lower-level TQSocketDevice class.
+
+ \warning Because TQt doesn't use the native socketstream
+ implementation on Mac OS X, TQSocket has an implicit transfer
+ latency of 100ms. You can achieve lower latency on Mac OS X by
+ using TQSocketDevice instead.

+\endif
+
+ \ingroup io
+ \module network
+
+ This class provides a low level API for working with sockets. Users of
+ this class are assumed to have networking experience. For most users the
+ TQSocket class provides a much easier and high level alternative, but
+ certain things (like UDP) can't be done with TQSocket and if you need a
+ platform-independent API for those, TQSocketDevice is the right choice.
+
+ The essential purpose of the class is to provide a TQIODevice that
+ works on sockets, wrapped in a platform-independent API.
+
+ When calling connect() or bind(), TQSocketDevice detects the
+ protocol family (IPv4, IPv6) automatically. Passing the protocol
+ family to TQSocketDevice's constructor or to setSocket() forces
+ creation of a socket device of a specific protocol. If not set, the
+ protocol will be detected at the first call to connect() or bind().

+ \enum TQSocketDevice::Protocol
+
+ This enum type describes the protocol family of the socket. Possible values
+ are:

+ \value IPv6 The socket is an IPv6 socket.
+ \value Unknown The protocol family of the socket is not known. This can
+ happen if you use TQSocketDevice with an already existing socket; it
+ tries to determine the protocol family, but this can fail if the

+ \value Inaccessible The operating system or firewall prohibited
+ the action.
+
+ \value NoResources The operating system ran out of a resource.
+
+ \value InternalError An internal error occurred in TQSocketDevice.
+
+ \value Impossible An attempt was made to do something which makes
+ no sense. For example:
+ \code
+ ::close( sd->socket() );
+ sd->writeBlock( someData, 42 );
+ \endcode
+ The libc ::close() closes the socket, but TQSocketDevice is not aware
+ of this. So when you call writeBlock(), the impossible happens.
+
+ \value NoFiles The operating system will not let TQSocketDevice open
+ another file.
