<h2>Detailed Description</h2>
<p>The QUrl class provides a convenient interface for working with URLs.</p>
<p>It can parse and construct URLs in both encoded and unencoded form. QUrl also has support for internationalized domain names (IDNs).</p>
<p>The most common way to use QUrl is to initialize it via the constructor by passing a <a href="qstring.html">QString</a>. Otherwise, <a href="qurl.html#setUrl">setUrl</a>() and <a href="qurl.html#setEncodedUrl">setEncodedUrl</a>() can also be used.</p>
<p>URLs can be represented in two forms: encoded or unencoded. The unencoded representation is suitable for showing to users, but the encoded representation is typically what you would send to a web server. For example, the unencoded URL "http://bü<tt></tt>hler.example.com" would be sent to the server as "http://xn--bhler-kva.example.com/List%20of%20applicants.xml".</p>
<p>A URL can also be constructed piece by piece by calling <a href="qurl.html#setScheme">setScheme</a>(), <a href="qurl.html#setUserName">setUserName</a>(), <a href="qurl.html#setPassword">setPassword</a>(), <a href="qurl.html#setHost">setHost</a>(), <a href="qurl.html#setPort">setPort</a>(), <a href="qurl.html#setPath">setPath</a>(), <a href="qurl.html#setEncodedQuery">setEncodedQuery</a>() and <a href="qurl.html#setFragment">setFragment</a>(). Some convenience functions are also available: <a href="qurl.html#setAuthority">setAuthority</a>() sets the user name, password, host and port. <a href="qurl.html#setUserInfo">setUserInfo</a>() sets the user name and password at once.</p>
<p>Call <a href="qurl.html#isValid">isValid</a>() to check if the URL is valid. This can be done at any point during the constructing of a URL.</p>
<p>Constructing a query is particularly convenient through the use of <a href="qurl.html#setQueryItems">setQueryItems</a>(), <a href="qurl.html#addQueryItem">addQueryItem</a>() and <a href="qurl.html#removeQueryItem">removeQueryItem</a>(). Use <a href="qurl.html#setQueryDelimiters">setQueryDelimiters</a>() to customize the delimiters used for generating the query string.</p>
<p>For the convenience of generating encoded URL strings or query strings, there are two static functions called <a href="qurl.html#fromPercentEncoding">fromPercentEncoding</a>() and <a href="qurl.html#toPercentEncoding">toPercentEncoding</a>() which deal with percent encoding and decoding of QStrings.</p>
<p>Calling <a href="qurl.html#isRelative">isRelative</a>() will tell whether or not the URL is relative. A relative URL can be resolved by passing it as argument to <a href="qurl.html#resolved">resolved</a>(), which returns an absolute URL. <a href="qurl.html#isParentOf">isParentOf</a>() is used for determining whether one URL is a parent of another.</p>
<p><a href="qurl.html#fromLocalFile">fromLocalFile</a>() constructs a QUrl by parsing a local file path. <a href="qurl.html#toLocalFile">toLocalFile</a>() converts a URL to a local file path.</p>
<p>The human readable representation of the URL is fetched with <a href="qurl.html#toString">toString</a>(). This representation is appropriate for displaying a URL to a user in unencoded form. The encoded form however, as returned by <a href="qurl.html#toEncoded">toEncoded</a>(), is for internal use, passing to web servers, mail clients and so on.</p>
<p>QUrl conforms to the URI specification from <a href="http://www.rfc-editor.org/rfc/rfc3986.txt">RFC 3986</a> (Uniform Resource Identifier: Generic Syntax), and includes scheme extensions from <a href="http://www.rfc-editor.org/rfc/rfc1738.txt">RFC 1738</a> (Uniform Resource Locators). Case folding rules in QUrl conform to <a href="http://www.rfc-editor.org/rfc/rfc3491.txt">RFC 3491</a> (Nameprep: A Stringprep Profile for Internationalized Domain Names (IDN)).</p>

<p>In TolerantMode, the parser corrects the following invalid input:</p>
<ul>
<li>Spaces and "%20": If an encoded URL contains a space, this will be replaced with "%20". If a decoded URL contains "%20", this will be replaced with a single space before the URL is parsed.</li>
<li>Single "%" characters: Any occurrences of a percent character "%" not followed by exactly two hexadecimal characters (e.g., "13% coverage.html") will be replaced by "%25".</li>
<li>Reserved and unreserved characters: An encoded URL should only contain a few characters as literals; all other characters should be percent-encoded. In TolerantMode, these characters will be automatically percent-encoded where they are not allowed: space / double-quote / "<" / ">" / "[" / "" / "]" / "^" / "`" / "{" / "|" / "}"</li>

<p>Returns a valid URL from a user supplied <i>userInput</i> string if one can be deducted. In the case that is not possible, an invalid <a href="qurl.html#QUrl">QUrl</a>() is returned.</p>
<p>Most applications that can browse the web, allow the user to input a URL in the form of a plain string. This string can be manually typed into a location bar, obtained from the clipboard, or passed in via command line arguments.</p>
<p>When the string is not already a valid URL, a best guess is performed, making various web related assumptions.</p>
<p>In the case the string corresponds to a valid file path on the system, a file:// URL is constructed, using <a href="qurl.html#fromLocalFile">QUrl::fromLocalFile</a>().</p>
<p>If that is not the case, an attempt is made to turn the string into a http:// or ftp:// URL. The latter in the case the string starts with 'ftp'. The result is then passed through <a href="qurl.html">QUrl</a>'s tolerant parser, and in the case or success, a valid <a href="qurl.html">QUrl</a> is returned, or else a <a href="qurl.html#QUrl">QUrl</a>().</p>

<li>When creating an URL <a href="qstring.html">QString</a> from a <a href="qbytearray.html">QByteArray</a> or a char*, always use <a href="qstring.html#fromUtf8">QString::fromUtf8</a>().</li>
<li>Favor the use of <a href="qurl.html#fromEncoded">QUrl::fromEncoded</a>() and <a href="qurl.html#toEncoded">QUrl::toEncoded</a>() instead of <a href="qurl.html">QUrl</a>(string) and <a href="qurl.html#toString">QUrl::toString</a>() when converting <a href="qurl.html">QUrl</a> to/from string.</li>

<h3 class="fn"><a name="resolved"></a>QUrl QUrl::resolved ( const QUrl & <i>relative</i> ) const</h3>
<p>Returns the result of the merge of this URL with <i>relative</i>. This URL is used as a base to convert <i>relative</i> to an absolute URL.</p>
<p>If <i>relative</i> is not a relative URL, this function will return <i>relative</i> directly. Otherwise, the paths of the two URLs are merged, and the new URL returned has the scheme and authority of the base URL, but with the merged path, as in the following example:</p>

qDebug(baseUrl.resolved(relativeUrl).toString());
<span class="comment"> // prints "http://qt.nokia.com/products/solutions"</span></pre>
<p>Calling resolved() with ".." returns a <a href="qurl.html">QUrl</a> whose directory is one level higher than the original. Similarly, calling resolved() with "../.." removes two levels from the path. If <i>relative</i> is "/", the path becomes "/".</p>

<p>Sets the authority of the URL to <i>authority</i>.</p>
<p>The authority of a URL is the combination of user info, a host name and a port. All of these elements are optional; an empty authority is therefore valid.</p>
<p>The user info and host are separated by a '<a href="examples-overview.html">@</a>', and the host and port are separated by a ':'. If the user info is empty, the '<a href="examples-overview.html">@</a>' must be omitted; although a stray ':' is permitted if the port is empty.</p>

<p>Sets the URL's fragment to the percent-encoded <i>fragment</i>. The fragment is the last part of the URL, represented by a '#' followed by a string of characters. It is typically used in HTTP for referring to a certain link or point on a page:</p>
<p align="center"><img src="images/qurl-fragment.png" /></p><p>The fragment is sometimes also referred to as the URL "reference".</p>
<p>Passing an argument of QByteArray() (a null <a href="qbytearray.html">QByteArray</a>) will unset the fragment. Passing an argument of <a href="qbytearray.html">QByteArray</a>("") (an empty but not null <a href="qbytearray.html">QByteArray</a>) will set the fragment to an empty string (as if the original URL had a lone "#").</p>

<p>Sets the query string of the URL to <i>query</i>. The string is inserted as-is, and no further encoding is performed when calling <a href="qurl.html#toEncoded">toEncoded</a>().</p>
<p>This function is useful if you need to pass a query string that does not fit into the key-value pattern, or that uses a different scheme for encoding special characters than what is suggested by <a href="qurl.html">QUrl</a>.</p>
<p>Passing a value of QByteArray() to <i>query</i> (a null <a href="qbytearray.html">QByteArray</a>) unsets the query completely. However, passing a value of <a href="qbytearray.html">QByteArray</a>("") will set the query to an empty value, as if the original URL had a lone "?".</p>

<h3 class="fn"><a name="QT_NO_URL_CAST_FROM_STRING"></a>QT_NO_URL_CAST_FROM_STRING</h3>
<p>Disables automatic conversions from <a href="qstring.html">QString</a> (or char *) to <a href="qurl.html">QUrl</a>.</p>
<p>Compiling your code with this define is useful when you have a lot of code that uses <a href="qstring.html">QString</a> for file names and you wish to convert it to use <a href="qurl.html">QUrl</a> for network transparency. In any code that uses <a href="qurl.html">QUrl</a>, it can help avoid missing <a href="qurl.html#resolved">QUrl::resolved</a>() calls, and other misuses of <a href="qstring.html">QString</a> to <a href="qurl.html">QUrl</a> conversions.</p>
<p>For example, if you have code like</p>
<pre><font color="#404040"> url = filename; // probably not what you want</font></pre>
<p>you can rewrite it as</p>
<pre> url = QUrl::fromLocalFile(filename);
url = baseurl.resolved(QUrl(filename));</pre>
