\class QUrl qurl.h
\brief The QUrl class provides a URL parser and simplifies working with URLs.
\if defined(commercial)
It is part of the <a href="commercialeditions.html">Qt Enterprise Edition</a>.
\endif
\ingroup io
\ingroup misc
\mainclass
\module network
The QUrl class is provided for simple work with URLs. It can
parse, decode, encode, etc.
QUrl works with the decoded path and encoded query in turn.
Example:
<tt>http://www.trolltech.com:80/cgi-bin/test%20me.pl?cmd=Hello%20you</tt>
\table
\header \i Function \i Returns
\row \i \l protocol() \i "http"
\row \i \l host() \i "www.trolltech.com"
\row \i \l port() \i 80
\row \i \l path() \i "/cgi-bin/test&nbsp;me.pl"
\row \i \l fileName() \i "test&nbsp;me.pl"
\row \i \l query() \i "cmd=Hello%20you"
\endtable
Example:
<tt>http://doc.trolltech.com/qdockarea.html#lines</tt>
\table
\header \i Function \i Returns
\row \i \l protocol() \i "http"
\row \i \l host() \i "doc.trolltech.com"
\row \i \l fileName() \i "qdockarea.html"
\row \i \l ref() \i "lines"
\endtable
The individual parts of a URL can be set with setProtocol(),
setHost(), setPort(), setPath(), setFileName(), setRef() and
setQuery(). A URL could contain, for example, an ftp address which
requires a user name and password; these can be set with setUser()
and setPassword().
Because path is always encoded internally you must not use "%00"
in the path, although this is okay (but not recommended) for the
query.
QUrl is normally used like this:
\code
QUrl url( "http://www.trolltech.com" );
// or
QUrl url( "file:/home/myself/Mail", "Inbox" );
\endcode
You can then access and manipulate the various parts of the URL.
To make it easy to work with QUrls and QStrings, QUrl implements
the necessary cast and assignment operators so you can do
following:
\code
QUrl url( "http://www.trolltech.com" );
QString s = url;
// or
QString s( "http://www.trolltech.com" );
QUrl url( s );
\endcode
Use the static functions, encode() and decode() to encode or
decode a URL in a string. (They operate on the string in-place.)
The isRelativeUrl() static function returns TRUE if the given
string is a relative URL.
If you want to use a URL to work on a hierarchical structure (e.g.
a local or remote filesystem), you might want to use the subclass
QUrlOperator.

}
/*!
Constructs an URL taking \a url as the base (context) and
\a relUrl as a relative URL to \a url. If \a relUrl is not relative,
\a relUrl is taken as the new URL.
For example, the path of
\code
QUrl url( "ftp://ftp.trolltech.com/qt/source", "qt-2.1.0.tar.gz" );
\endcode
will be "/qt/srource/qt-2.1.0.tar.gz".
On the other hand,
\code
QUrl url( "ftp://ftp.trolltech.com/qt/source", "/usr/local" );
\endcode
will result in a new URL, "ftp://ftp.trolltech.com/usr/local",
because "/usr/local" isn't relative.
Similarly,
\code
QUrl url( "ftp://ftp.trolltech.com/qt/source", "file:/usr/local" );
\endcode
will result in a new URL, with "/usr/local" as the path
and "file" as the protocol.
Normally it is expected that the path of \a url points to a
directory, even if the path has no slash at the end. But if you
want the constructor to handle the last part of the path as a file
name if there is no slash at the end, and to let it be replaced by
the file name of \a relUrl (if it contains one), set \a checkSlash
to TRUE.
