+
+    \brief The TQUrlOperator class provides common operations on URLs.
+\if defined(commercial)
+    It is part of the <a href="commercialeditions.html">TQt Enterprise Edition</a>.
+\endif
+
+    \ingroup io
+    \ingroup misc
+    \mainclass
+
+    \module network
+
+    This class operates on hierarchical structures (such as
+    filesystems) using URLs. Its API facilitates all the common
+    operations:
+    \table
+    \header \i Operation	\i Function
+    \row \i List files		\i \l listChildren()
+    \row \i Make a directory	\i \l mkdir()
+    \row \i Remove a file	\i \l remove()
+    \row \i Rename a file	\i \l rename()
+    \row \i Get a file		\i \l get()
+    \row \i Put a file		\i \l put()
+    \row \i Copy a file		\i \l copy()
+    \endtable
+
+    You can obtain additional information about the URL with isDir()
+    and info(). If a directory is to be traversed using
+    listChildren(), a name filter can be set with setNameFilter().
+
+    A TQUrlOperator can be used like this, for example to download a
+    file (and assuming that the FTP protocol is \link
+    qInitNetworkProtocols() registered\endlink):
+    \code
+    TQUrlOperator *op = new TQUrlOperator();
+    op->copy( TQString("ftp://ftp.trolltech.com/qt/source/qt-2.1.0.tar.gz"),
+	     "file:/tmp" );
+    \endcode
+
+    If you want to be notified about success/failure, progress, etc.,
+    you can connect to TQUrlOperator's signals, e.g. to start(),
+    newChildren(), createdDirectory(), removed(), data(),
+    dataTransferProgress(), startedNextCopy(),
+    connectionStateChanged(), finished(), etc. A network operation can
+    be stopped with stop().
+
+    The class uses the functionality of registered network protocols
+    to perform these operations. Depending of the protocol of the URL,
+    it uses an appropriate network protocol class for the operations.
+    Each of the operation functions of TQUrlOperator creates a
+    TQNetworkOperation object that describes the operation and puts it
+    into the operation queue for the network protocol used. If no
+    suitable protocol could be found (because no implementation of the
+    necessary network protocol is registered), the URL operator emits
+    errors. Not every protocol supports every operation, but error
+    handling deals with this problem.
+
+    To register the available network protocols, use the
+    qInitNetworkProtocols() function. The protocols currently
+    supported are:
+    \list
+    \i \link TQFtp FTP\endlink,
+    \i \link TQHttp HTTP\endlink,
+    \i \link TQLocalFs local file system\endlink.
+    \endlist
+
+    For more information about the TQt Network Architecture see the
+    \link network.html TQt Network Documentation\endlink.

+    Tells the network protocol to get data from \a location or, if
+    this is TQString::null, to get data from the location to which this
+    URL points (see TQUrl::fileName() and TQUrl::encodedPathAndQuery()).
+    What happens then depends on the network protocol. The data()
+    signal is emitted when data comes in. Because it's unlikely that
+    all data will come in at once, it is common for multiple data()
+    signals to be emitted. The dataTransferProgress() signal is
+    emitted while processing the operation. At the end, finished()
+    (with success or failure) is emitted, so check the state of the
+    network operation object to see whether or not the operation was
+    successful.
+
+    If \a location is TQString::null, the path of this TQUrlOperator
+    should point to a file when you use this operation. If \a location
+    is not empty, it can be a relative URL (a child of the path to
+    which the TQUrlOperator points) or an absolute URL.
+
+    For example, to get a web page you might do something like this:
+
+    \code
+    TQUrlOperator op( "http://www.whatever.org/cgi-bin/search.pl?cmd=Hello" );
+    op.get();
+    \endcode
+
+    For most other operations, the path of the TQUrlOperator must point
+    to a directory. If you want to download a file you could do the
+    following:
+
+    \code
+    TQUrlOperator op( "ftp://ftp.whatever.org/pub" );
+    // do some other stuff like op.listChildren() or op.mkdir( "new_dir" )
+    op.get( "a_file.txt" );
+    \endcode
+
+    This will get the data of ftp://ftp.whatever.org/pub/a_file.txt.
+
+    \e Never do anything like this:
+    \code
+    TQUrlOperator op( "http://www.whatever.org/cgi-bin" );
+    op.get( "search.pl?cmd=Hello" ); // WRONG!
+    \endcode
+
+    If \a location is not empty and relative it must not contain any
+    queries or references, just the name of a child. So if you need to
+    specify a query or reference, do it as shown in the first example
+    or specify the full URL (such as
+    http://www.whatever.org/cgi-bin/search.pl?cmd=Hello) as \a location.
