+    \class Q3UrlOperator
+
+    \brief The Q3UrlOperator class provides common operations on URLs.
+
+    \compat
+
+    \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 Q3UrlOperator can be used like this, for example to download a
+    file (and assuming that the FTP protocol is registered):
+    \snippet doc/src/snippets/code/src_qt3support_network_q3urloperator.cpp 0
+
+    If you want to be notified about success/failure, progress, etc.,
+    you can connect to Q3UrlOperator'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 Q3UrlOperator creates a
+    Q3NetworkOperation 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 Q3Ftp FTP\endlink,
+    \i \link Q3Http HTTP\endlink,
+    \i \link Q3LocalFs local file system\endlink.
+    \endlist

+    Tells the network protocol to get data from \a location or, if

+    URL points (see Q3Url::fileName() and Q3Url::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

+
+    If \a location is empty, the path of this Q3UrlOperator
+    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 Q3UrlOperator points) or an absolute URL.
+
+    For example, to get a web page you might do something like this:
+
+    \snippet doc/src/snippets/code/src_qt3support_network_q3urloperator.cpp 1
+
+    For most other operations, the path of the Q3UrlOperator must point
+    to a directory. If you want to download a file you could do the
+    following:
+
+    \snippet doc/src/snippets/code/src_qt3support_network_q3urloperator.cpp 2
+
+    This will get the data of ftp://ftp.whatever.org/pub/a_file.txt.
+
+    \e Never do anything like this:
+    \snippet doc/src/snippets/code/src_qt3support_network_q3urloperator.cpp 3
+
+    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
