-
-
-The TQNetworkProtocol class provides a common API for network protocols.
-
-<p>
-
-
-
-<p> This is a base class which should be used for network protocols
-implementations that can then be used in TQt (e.g. in the file
-dialog) together with the <a href="qurloperator.html">TQUrlOperator</a>.
-<p> The easiest way to implement a new network protocol is to
-reimplement the operation*() methods, e.g. <a href="#operationGet">operationGet</a>(), etc.
-Only the supported operations should be reimplemented. To specify
-which operations are supported, also reimplement
-<a href="#supportedOperations">supportedOperations</a>() and return an int that is OR'd together
-using the supported operations from the <a href="#Operation-enum">TQNetworkProtocol::Operation</a> enum.
-<p> When you implement a network protocol this way, it is important to
-emit the correct signals. Also, always emit the <a href="#finished">finished</a>() signal
-when an operation is done (on success <em>and</em> on failure). TQt
-relies on correctly emitted finished() signals.
-<p> For a detailed description of the TQt Network Architecture and how
-to implement and use network protocols in TQt, see the <a href="network.html">TQt Network Documentation</a>.
-<p>See also <a href="io.html">Input/Output and Networking</a>.
-
-<hr><h2>Member Type Documentation</h2>
-<h3 class=fn><a name="ConnectionState-enum"></a>TQNetworkProtocol::ConnectionState</h3>
-
-<p> When the connection state of a network protocol changes it emits
-the signal <a href="#connectionStateChanged">connectionStateChanged</a>(). The first argument is one of
-the following values:
-<ul>
-<li><tt>TQNetworkProtocol::ConHostFound</tt> - Host has been found.
-<li><tt>TQNetworkProtocol::ConConnected</tt> - Connection to the host has been established.
-<li><tt>TQNetworkProtocol::ConClosed</tt> - Connection has been closed.
-</ul>
-<h3 class=fn><a name="Error-enum"></a>TQNetworkProtocol::Error</h3>
-
-<p> When an operation fails (finishes unsuccessfully), the
-<a href="qnetworkoperation.html">TQNetworkOperation</a> of the operation returns an error code which has
-one of the following values:
-<ul>
-<li><tt>TQNetworkProtocol::NoError</tt> - No error occurred.
-<li><tt>TQNetworkProtocol::ErrValid</tt> - The URL you are operating on is not valid.
-<li><tt>TQNetworkProtocol::ErrUnknownProtocol</tt> - There is no protocol implementation
-available for the protocol of the URL you are operating on (e.g.
-if the protocol is http and no http implementation has been
-registered).
-<li><tt>TQNetworkProtocol::ErrUnsupported</tt> - The operation is not supported by the
-protocol.
-<li><tt>TQNetworkProtocol::ErrParse</tt> - The URL could not be parsed correctly.
-<li><tt>TQNetworkProtocol::ErrLoginIncorrect</tt> - You needed to login but the username
-or password is wrong.
-<li><tt>TQNetworkProtocol::ErrHostNotFound</tt> - The specified host (in the URL) couldn't
-be found.
-<li><tt>TQNetworkProtocol::ErrListChildren</tt> - An error occurred while listing the
-children (files).
-<li><tt>TQNetworkProtocol::ErrMkDir</tt> - An error occurred when creating a directory.
-<li><tt>TQNetworkProtocol::ErrRemove</tt> - An error occurred when removing a child (file).
-<li><tt>TQNetworkProtocol::ErrRename</tt> - An error occurred when renaming a child (file).
-<li><tt>TQNetworkProtocol::ErrGet</tt> - An error occurred while getting (retrieving) data.
-<li><tt>TQNetworkProtocol::ErrPut</tt> - An error occurred while putting (uploading) data.
-<li><tt>TQNetworkProtocol::ErrFileNotExisting</tt> - A file which is needed by the operation
-doesn't exist.
-<li><tt>TQNetworkProtocol::ErrPermissionDenied</tt> - Permission for doing the operation has
-been denied.
-</ul><p> You should also use these error codes when implementing custom
-network protocols. If this is not possible, you can define your own
-error codes by using integer values that don't conflict with any
-of these values.
-
-<h3 class=fn><a name="Operation-enum"></a>TQNetworkProtocol::Operation</h3>
-
-<p> This enum lists the possible operations that a network protocol
-can support. <a href="#supportedOperations">supportedOperations</a>() returns an int of these that is
-OR'd together. Also, the type() of a <a href="qnetworkoperation.html">TQNetworkOperation</a> is always
-one of these values.
-<ul>
-<li><tt>TQNetworkProtocol::OpListChildren</tt> - List the children of a URL, e.g. of a directory.
-<li><tt>TQNetworkProtocol::OpMkDir</tt> - Create a directory.
-<li><tt>TQNetworkProtocol::OpRemove</tt> - Remove a child (e.g. a file).
-<li><tt>TQNetworkProtocol::OpRename</tt> - Rename a child (e.g. a file).
-<li><tt>TQNetworkProtocol::OpGet</tt> - Get data from a location.
-<li><tt>TQNetworkProtocol::OpPut</tt> - Put data to a location.
-</ul>
-<h3 class=fn><a name="State-enum"></a>TQNetworkProtocol::State</h3>
-
-<p> This enum contains the state that a <a href="qnetworkoperation.html">TQNetworkOperation</a> can have.
-<ul>
-<li><tt>TQNetworkProtocol::StWaiting</tt> - The operation is in the TQNetworkProtocol's queue
-waiting to be prcessed.
-<li><tt>TQNetworkProtocol::StInProgress</tt> - The operation is being processed.
-<li><tt>TQNetworkProtocol::StDone</tt> - The operation has been processed succesfully.
-<li><tt>TQNetworkProtocol::StFailed</tt> - The operation has been processed but an error occurred.
-<li><tt>TQNetworkProtocol::StStopped</tt> - The operation has been processed but has been
-stopped before it finished, and is waiting to be processed.
-</ul><p>
-<hr><h2>Member Function Documentation</h2>
-<h3 class=fn><a name="TQNetworkProtocol"></a>TQNetworkProtocol::TQNetworkProtocol ()
-</h3>
-Constructor of the network protocol base class. Does some
-initialization and connecting of signals and slots.
-
-<h3 class=fn><a name="~TQNetworkProtocol"></a>TQNetworkProtocol::~TQNetworkProtocol ()<tt> [virtual]</tt>
-</h3>
-Destructor.
-
-<h3 class=fn>void <a name="addOperation"></a>TQNetworkProtocol::addOperation ( <a href="qnetworkoperation.html">TQNetworkOperation</a>&nbsp;*&nbsp;op )<tt> [virtual]</tt>
-</h3>
-Adds the operation <em>op</em> to the operation queue. The operation
-will be processed as soon as possible. This method returns
-immediately.
-
-<h3 class=fn>bool <a name="autoDelete"></a>TQNetworkProtocol::autoDelete () const
-</h3>
-Returns TRUE if auto-deleting is enabled; otherwise returns FALSE.
-<p> <p>See also <a href="#setAutoDelete">TQNetworkProtocol::setAutoDelete</a>().
-
-<h3 class=fn>bool <a name="checkConnection"></a>TQNetworkProtocol::checkConnection ( <a href="qnetworkoperation.html">TQNetworkOperation</a>&nbsp;*&nbsp;op )<tt> [virtual protected]</tt>
-</h3>
-For processing operations the network protocol base class calls
-this method quite often. This should be reimplemented by new
-network protocols. It should return TRUE if the connection is OK
-(open); otherwise it should return FALSE. If the connection is not
-open the protocol should open it.
-<p> If the connection can't be opened (e.g. because you already tried
-but the host couldn't be found), set the state of <em>op</em> to
-TQNetworkProtocol::StFailed and emit the <a href="#finished">finished</a>() signal with
-this <a href="qnetworkoperation.html">TQNetworkOperation</a> as argument.
-<p> <em>op</em> is the operation that needs an open connection.
-
-<p>Example: <a href="networkprotocol-example.html#x673">network/networkprotocol/nntp.cpp</a>.
-<h3 class=fn>void <a name="clearOperationQueue"></a>TQNetworkProtocol::clearOperationQueue ()<tt> [virtual]</tt>
-</h3>
-Clears the operation queue.
-
-<h3 class=fn>void <a name="connectionStateChanged"></a>TQNetworkProtocol::connectionStateChanged ( int&nbsp;state, const&nbsp;<a href="qstring.html">TQString</a>&nbsp;&amp;&nbsp;data )<tt> [signal]</tt>
-</h3>
-
-<p> This signal is emitted whenever the state of the connection of the
-network protocol is changed. <em>state</em> describes the new state,
-which is one of, <a href="#ConnectionState-enum">ConHostFound</a>, <a href="#ConnectionState-enum">ConConnected</a> or <a href="#ConnectionState-enum">ConClosed</a>.
-<em>data</em> is a message text.
-
-<h3 class=fn>void <a name="createdDirectory"></a>TQNetworkProtocol::createdDirectory ( const&nbsp;<a href="qurlinfo.html">TQUrlInfo</a>&nbsp;&amp;&nbsp;i, <a href="qnetworkoperation.html">TQNetworkOperation</a>&nbsp;*&nbsp;op )<tt> [signal]</tt>
-</h3>
-
-<p> This signal is emitted when mkdir() has been succesful and the
-directory has been created. <em>i</em> holds the information about the
-new directory. <em>op</em> is the pointer to the operation object which
-contains all the information about the operation, including the
-state, etc. Using op->arg( 0 ), you can get the file name of the
-new directory.
-<p> When a protocol emits this signal, TQNetworkProtocol is smart
-enough to let the <a href="qurloperator.html">TQUrlOperator</a>, which is used by the network
-protocol, emit its corresponding signal.
-
-<h3 class=fn>void <a name="data"></a>TQNetworkProtocol::data ( const&nbsp;<a href="qbytearray.html">TQByteArray</a>&nbsp;&amp;&nbsp;data, <a href="qnetworkoperation.html">TQNetworkOperation</a>&nbsp;*&nbsp;op )<tt> [signal]</tt>
-</h3>
-
-<p> This signal is emitted when new <em>data</em> has been received after
-calling get() or put(). <em>op</em> holds the name of the file from
-which data is retrieved or uploaded in its first argument, and the
-(raw) data in its second argument. You can get them with
-op->arg( 0 ) and op->rawArg( 1 ). <em>op</em> is the pointer to the
-operation object, which contains all the information about the
-operation, including the state, etc.
-<p> When a protocol emits this signal, TQNetworkProtocol is smart
-enough to let the <a href="qurloperator.html">TQUrlOperator</a> (which is used by the network
-protocol) emit its corresponding signal.
-
-<h3 class=fn>void <a name="dataTransferProgress"></a>TQNetworkProtocol::dataTransferProgress ( int&nbsp;bytesDone, int&nbsp;bytesTotal, <a href="qnetworkoperation.html">TQNetworkOperation</a>&nbsp;*&nbsp;op )<tt> [signal]</tt>
-</h3>
-
-<p> This signal is emitted during the transfer of data (using put() or
-get()). <em>bytesDone</em> is how many bytes of <em>bytesTotal</em> have been
-transferred. <em>bytesTotal</em> may be -1, which means that the total
-number of bytes is not known. <em>op</em> is the pointer to the
-operation object which contains all the information about the
-operation, including the state, etc.
-<p> When a protocol emits this signal, TQNetworkProtocol is smart
-enough to let the <a href="qurloperator.html">TQUrlOperator</a>, which is used by the network
-protocol, emit its corresponding signal.
-
-<h3 class=fn>void <a name="finished"></a>TQNetworkProtocol::finished ( <a href="qnetworkoperation.html">TQNetworkOperation</a>&nbsp;*&nbsp;op )<tt> [signal]</tt>
-</h3>
-
-<p> This signal is emitted when an operation finishes. This signal is
-always emitted, for both success and failure. <em>op</em> is the pointer
-to the operation object which contains all the information about
-the operation, including the state, etc. Check the state and error
-code of the operation object to determine whether or not the
-operation was successful.
-<p> When a protocol emits this signal, TQNetworkProtocol is smart
-enough to let the <a href="qurloperator.html">TQUrlOperator</a>, which is used by the network
-protocol, emit its corresponding signal.
-
-<h3 class=fn><a href="qnetworkprotocol.html">TQNetworkProtocol</a>&nbsp;* <a name="getNetworkProtocol"></a>TQNetworkProtocol::getNetworkProtocol ( const&nbsp;<a href="qstring.html">TQString</a>&nbsp;&amp;&nbsp;protocol )<tt> [static]</tt>
-</h3>
-Static method to get a new instance of the network protocol <em>protocol</em>. For example, if you need to do some FTP operations, do
-the following:
-<pre>
- <a href="qftp.html">TQFtp</a> *ftp = TQNetworkProtocol::<a href="#getNetworkProtocol">getNetworkProtocol</a>( "ftp" );
- </pre>
-
-This returns a pointer to a new instance of an ftp implementation
-or null if no protocol for ftp was registered. The ownership of
-the pointer is transferred to you, so you must delete it if you
-don't need it anymore.
-<p> Normally you should not work directly with network protocols, so
-you will not need to call this method yourself. Instead, use
-<a href="qurloperator.html">TQUrlOperator</a>, which makes working with network protocols much more
-convenient.
-<p> <p>See also <a href="qurloperator.html">TQUrlOperator</a>.
-
-<h3 class=fn>bool <a name="hasOnlyLocalFileSystem"></a>TQNetworkProtocol::hasOnlyLocalFileSystem ()<tt> [static]</tt>
-</h3>
-Returns TRUE if the only protocol registered is for working on the
-local filesystem; returns FALSE if other network protocols are
-also registered.
-
-<h3 class=fn>void <a name="itemChanged"></a>TQNetworkProtocol::itemChanged ( <a href="qnetworkoperation.html">TQNetworkOperation</a>&nbsp;*&nbsp;op )<tt> [signal]</tt>
-</h3>
-
-<p> This signal is emitted whenever a file which is a child of this
-URL has been changed, e.g. by successfully calling rename(). <em>op</em>
-holds the original and the new file names in the first and second
-arguments, accessible with op->arg( 0 ) and op->arg( 1 )
-respectively. <em>op</em> is the pointer to the operation object which
-contains all the information about the operation, including the
-state, etc.
-<p> When a protocol emits this signal, TQNetworkProtocol is smart
-enough to let the <a href="qurloperator.html">TQUrlOperator</a>, which is used by the network
-protocol, emit its corresponding signal.
-
-<h3 class=fn>void <a name="newChild"></a>TQNetworkProtocol::newChild ( const&nbsp;<a href="qurlinfo.html">TQUrlInfo</a>&nbsp;&amp;&nbsp;i, <a href="qnetworkoperation.html">TQNetworkOperation</a>&nbsp;*&nbsp;op )<tt> [signal]</tt>
-</h3>
-
-<p> This signal is emitted if a new child (file) has been read.
-TQNetworkProtocol automatically connects it to a slot which creates
-a list of <a href="qurlinfo.html">TQUrlInfo</a> objects (with just one TQUrlInfo <em>i</em>) and emits
-the <a href="#newChildren">newChildren</a>() signal with this list. <em>op</em> is the pointer to
-the operation object which contains all the information about the
-operation that has finished, including the state, etc.
-<p> This is just a convenience signal useful for implementing your own
-network protocol. In all other cases connect to the newChildren()
-signal with its list of TQUrlInfo objects.
-
-<h3 class=fn>void <a name="newChildren"></a>TQNetworkProtocol::newChildren ( const&nbsp;<a href="qvaluelist.html">TQValueList</a>&lt;TQUrlInfo&gt;&nbsp;&amp;&nbsp;i, <a href="qnetworkoperation.html">TQNetworkOperation</a>&nbsp;*&nbsp;op )<tt> [signal]</tt>
-</h3>
-
-<p> This signal is emitted after listChildren() was called and new
-children (files) have been read from the list of files. <em>i</em> holds
-the information about the new children. <em>op</em> is the pointer to
-the operation object which contains all the information about the
-operation, including the state, etc.
-<p> When a protocol emits this signal, TQNetworkProtocol is smart
-enough to let the <a href="qurloperator.html">TQUrlOperator</a>, which is used by the network
-protocol, emit its corresponding signal.
-<p> When implementing your own network protocol and reading children,
-you usually don't read one child at once, but rather a list of
-them. That's why this signal takes a list of <a href="qurlinfo.html">TQUrlInfo</a> objects. If
-you prefer to read just one child at a time you can use the
-convenience signal <a href="#newChild">newChild</a>(), which takes a single TQUrlInfo
-object.
-
-<h3 class=fn>void <a name="operationGet"></a>TQNetworkProtocol::operationGet ( <a href="qnetworkoperation.html">TQNetworkOperation</a>&nbsp;*&nbsp;op )<tt> [virtual protected]</tt>
-</h3>
-When implementing a new network protocol, this method should be
-reimplemented if the protocol supports getting data; this method
-should then process the <a href="qnetworkoperation.html">TQNetworkOperation</a>.
-<p> When you reimplement this method it's very important that you emit
-the correct signals at the correct time (especially the <a href="#finished">finished</a>()
-signal after processing an operation). Take a look at the <a href="network.html">TQt Network Documentation</a> which describes in
-detail how to reimplement this method. You may also want to look

-</h3>
-Static method to register a network protocol for TQt. For example,
-if you have an implementation of NNTP (called Nntp) which is
-derived from TQNetworkProtocol, call:
-<pre>
- TQNetworkProtocol::<a href="#registerNetworkProtocol">registerNetworkProtocol</a>( "nntp", new TQNetworkProtocolFactory&lt;Nntp&gt; );
- </pre>
-
-after which your implementation is registered for future nntp
-operations.
-<p> The name of the protocol is given in <em>protocol</em> and a pointer to
-the protocol factory is given in <em>protocolFactory</em>.
-
-<h3 class=fn>void <a name="removed"></a>TQNetworkProtocol::removed ( <a href="qnetworkoperation.html">TQNetworkOperation</a>&nbsp;*&nbsp;op )<tt> [signal]</tt>
-</h3>
-
-<p> This signal is emitted when remove() has been succesful and the
-file has been removed. <em>op</em> holds the file name of the removed
-file in the first argument, accessible with op->arg( 0 ). <em>op</em> is
-the pointer to the operation object which contains all the
-information about the operation, including the state, etc.
-<p> When a protocol emits this signal, TQNetworkProtocol is smart
-enough to let the <a href="qurloperator.html">TQUrlOperator</a>, which is used by the network
-protocol, emit its corresponding signal.
-
-<h3 class=fn>void <a name="setAutoDelete"></a>TQNetworkProtocol::setAutoDelete ( bool&nbsp;b, int&nbsp;i = 10000 )<tt> [virtual]</tt>
-</h3>
-Because it's sometimes hard to take care of removing network
-protocol instances, TQNetworkProtocol provides an auto-delete
-mechanism. If you set <em>b</em> to TRUE, the network protocol instance
-is removed after it has been inactive for <em>i</em> milliseconds (i.e.
-<em>i</em> milliseconds after the last operation has been processed).
-If you set <em>b</em> to FALSE the auto-delete mechanism is switched
-off.
-<p> If you switch on auto-delete, the TQNetworkProtocol also deletes
-its <a href="qurloperator.html">TQUrlOperator</a>.
-
-<h3 class=fn>void <a name="setUrl"></a>TQNetworkProtocol::setUrl ( <a href="qurloperator.html">TQUrlOperator</a>&nbsp;*&nbsp;u )<tt> [virtual]</tt>
-</h3>
-Sets the <a href="qurloperator.html">TQUrlOperator</a>, on which the protocol works, to <em>u</em>.
-<p> <p>See also <a href="qurloperator.html">TQUrlOperator</a>.
-
-<h3 class=fn>void <a name="start"></a>TQNetworkProtocol::start ( <a href="qnetworkoperation.html">TQNetworkOperation</a>&nbsp;*&nbsp;op )<tt> [signal]</tt>
-</h3>
-
-<p> Some operations (such as listChildren()) emit this signal when
-they start processing the operation. <em>op</em> is the pointer to the
-operation object which contains all the information about the
-operation, including the state, etc.
-<p> When a protocol emits this signal, TQNetworkProtocol is smart
-enough to let the <a href="qurloperator.html">TQUrlOperator</a>, which is used by the network
-protocol, emit its corresponding signal.
-
-<h3 class=fn>void <a name="stop"></a>TQNetworkProtocol::stop ()<tt> [virtual]</tt>
-</h3>
-Stops the current operation that is being processed and clears all
-waiting operations.
-
-<h3 class=fn>int <a name="supportedOperations"></a>TQNetworkProtocol::supportedOperations () const<tt> [virtual]</tt>
-</h3>
-Returns an int that is OR'd together using the enum values of
-<a href="#Operation-enum">TQNetworkProtocol::Operation</a>, which describes which operations
-are supported by the network protocol. Should be reimplemented by
-new network protocols.
-
-<p>Example: <a href="networkprotocol-example.html#x676">network/networkprotocol/nntp.cpp</a>.
-<h3 class=fn><a href="qurloperator.html">TQUrlOperator</a>&nbsp;* <a name="url"></a>TQNetworkProtocol::url () const
-</h3>
-Returns the <a href="qurloperator.html">TQUrlOperator</a> on which the protocol works.
