51The QMimeSource class is an abstraction of objects which provide formatted data of a certain MIME type.
52<p>
53

55<p> <a href="dnd.html">Drag-and-drop</a> and
56<a href="qclipboard.html">clipboard</a> use this abstraction.
57<p> <p>See also <a href="http://www.isi.edu/in-notes/iana/assignments/media-types/
58 ">IANA list of MIME media types</a>, <a href="draganddrop.html">Drag And Drop Classes</a>, <a href="io.html">Input/Output and Networking</a>, and <a href="misc.html">Miscellaneous Classes</a>.

60<hr><h2>Member Function Documentation</h2>
61<h3 class=fn><a name="QMimeSource"></a>QMimeSource::QMimeSource ()
62</h3>
63Constructs a mime source and assigns a globally unique serial
64number to it.
65<p> <p>See also <a href="#serialNumber">serialNumber</a>().
66
67<h3 class=fn><a name="~QMimeSource"></a>QMimeSource::~QMimeSource ()<tt> [virtual]</tt>
68</h3>
69Provided to ensure that subclasses destroy themselves correctly.
70
71<h3 class=fn><a href="qbytearray.html">QByteArray</a> <a name="encodedData"></a>QMimeSource::encodedData ( const char * ) const<tt> [pure virtual]</tt>
72</h3>
73
74<p> Returns the encoded data of this object in the specified MIME
75format.
76<p> Subclasses must reimplement this function.
77
78<p>Reimplemented in <a href="qstoreddrag.html#encodedData">QStoredDrag</a>, <a href="qdropevent.html#encodedData">QDropEvent</a>, and <a href="qicondrag.html#encodedData">QIconDrag</a>.
79<h3 class=fn>const char * <a name="format"></a>QMimeSource::format ( int&nbsp;i = 0 ) const<tt> [pure virtual]</tt>
80</h3>
81
82<p> Returns the <em>i</em>-th supported MIME format, or 0.
83
84<p>Reimplemented in <a href="qdropevent.html#format">QDropEvent</a>.
85<h3 class=fn>bool <a name="provides"></a>QMimeSource::provides ( const&nbsp;char&nbsp;*&nbsp;mimeType ) const<tt> [virtual]</tt>
86</h3>
87Returns TRUE if the object can provide the data in format <em>mimeType</em>; otherwise returns FALSE.
88<p> If you inherit from QMimeSource, for consistency reasons it is
89better to implement the more abstract canDecode() functions such
90as <a href="qtextdrag.html#canDecode">QTextDrag::canDecode</a>() and <a href="qimagedrag.html#canDecode">QImageDrag::canDecode</a>().
91
92<p>Example: <a href="simple_dd-example.html#x2825">iconview/simple_dd/main.cpp</a>.
93<p>Reimplemented in <a href="qdropevent.html#provides">QDropEvent</a>.
94<h3 class=fn>int <a name="serialNumber"></a>QMimeSource::serialNumber () const
95</h3>
96
97<p> Returns the mime source's globally unique serial number.
