If a directory is to be traversed using -<a href="#listChildren">listChildren</a>(), a name filter can be set with <a href="#setNameFilter">setNameFilter</a>(). -<p> A TQUrlOperator can be used like this, for example to download a -file (and assuming that the FTP protocol is <a href="#qInitNetworkProtocols">registered</a>): -<pre> - TQUrlOperator *op = new TQUrlOperator(); - op-><a href="#copy">copy</a>( TQString("ftp://ftp.trolltech.com/qt/source/qt-2.1.0.tar.gz"), - "file:/tmp" ); - </pre> - -<p> If you want to be notified about success/failure, progress, etc., -you can connect to TQUrlOperator's signals, e.g. to <a href="#start">start</a>(), -<a href="#newChildren">newChildren</a>(), <a href="#createdDirectory">createdDirectory</a>(), <a href="#removed">removed</a>(), <a href="#data">data</a>(), -<a href="#dataTransferProgress">dataTransferProgress</a>(), <a href="#startedNextCopy">startedNextCopy</a>(), -<a href="#connectionStateChanged">connectionStateChanged</a>(), <a href="#finished">finished</a>(), etc. A network operation can -be stopped with <a href="#stop">stop</a>(). -<p> 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 -<a href="qnetworkoperation.html">TQNetworkOperation</a> 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. -<p> To register the available network protocols, use the -<a href="#qInitNetworkProtocols">qInitNetworkProtocols</a>() function. The protocols currently -supported are: -<ul> -<li> <a href="qftp.html">FTP</a>, -<li> <a href="qhttp.html">HTTP</a>, -<li> <a href="qlocalfs.html">local file system</a>. -</ul> -<p> For more information about the TQt Network Architecture see the -<a href="network.html">TQt Network Documentation</a>. -<p> <p>See also <a href="qnetworkprotocol.html">TQNetworkProtocol</a>, <a href="qnetworkoperation.html">TQNetworkOperation</a>, <a href="io.html">Input/Output and Networking</a>, and <a href="misc.html">Miscellaneous Classes</a>. - -<hr><h2>Member Function Documentation</h2> -<h3 class=fn><a name="TQUrlOperator"></a>TQUrlOperator::TQUrlOperator () -</h3> -Constructs a TQUrlOperator with an empty (i.e. invalid) URL. - -<h3 class=fn><a name="TQUrlOperator-2"></a>TQUrlOperator::TQUrlOperator ( const <a href="qstring.html">TQString</a> & url ) -</h3> -Constructs a TQUrlOperator using <em>url</em> and parses this string. -<p> If you pass strings like "/home/qt" the "file" protocol is -assumed. - -<h3 class=fn><a name="TQUrlOperator-3"></a>TQUrlOperator::TQUrlOperator ( const <a href="qurloperator.html">TQUrlOperator</a> & url ) -</h3> -Constructs a copy of <em>url</em>. - -<h3 class=fn><a name="TQUrlOperator-4"></a>TQUrlOperator::TQUrlOperator ( const <a href="qurloperator.html">TQUrlOperator</a> & url, const <a href="qstring.html">TQString</a> & relUrl, bool checkSlash = FALSE ) -</h3> -Constructs a TQUrlOperator.
