<hr><a name="details"></a><h2>Detailed Description</h2>
The TQMimeSource class is an abstraction of objects which provide formatted data of a certain MIME type.
<p>
<p> <a href="dnd.html">Drag-and-drop</a> and
<a href="ntqclipboard.html">clipboard</a> use this abstraction.
<p> <p>See also <a href="http://www.isi.edu/in-notes/iana/assignments/media-types/
">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>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQMimeSource"></a>TQMimeSource::TQMimeSource ()
</h3>
Constructs a mime source and assigns a globally unique serial
number to it.
<p> <p>See also <a href="#serialNumber">serialNumber</a>().
<h3 class=fn><a name="~TQMimeSource"></a>TQMimeSource::~TQMimeSource ()<tt> [virtual]</tt>
</h3>
Provided to ensure that subclasses destroy themselves correctly.
<h3 class=fn><a href="qbytearray.html">TQByteArray</a> <a name="encodedData"></a>TQMimeSource::encodedData ( const char * ) const<tt> [pure virtual]</tt>
</h3>
<p> Returns the encoded data of this object in the specified MIME
format.
<p> Subclasses must reimplement this function.
<p>Reimplemented in <a href="qstoreddrag.html#encodedData">TQStoredDrag</a>, <a href="qdropevent.html#encodedData">TQDropEvent</a>, and <a href="qicondrag.html#encodedData">TQIconDrag</a>.
<h3 class=fn>const char * <a name="format"></a>TQMimeSource::format ( int&nbsp;i = 0 ) const<tt> [pure virtual]</tt>
</h3>
<p> Returns the <em>i</em>-th supported MIME format, or 0.
<p>Reimplemented in <a href="qdropevent.html#format">TQDropEvent</a>.
<h3 class=fn>bool <a name="provides"></a>TQMimeSource::provides ( const&nbsp;char&nbsp;*&nbsp;mimeType ) const<tt> [virtual]</tt>
</h3>
Returns TRUE if the object can provide the data in format <em>mimeType</em>; otherwise returns FALSE.
<p> If you inherit from TQMimeSource, for consistency reasons it is
better to implement the more abstract canDecode() functions such
as <a href="qtextdrag.html#canDecode">TQTextDrag::canDecode</a>() and <a href="tqimagedrag.html#canDecode">TQImageDrag::canDecode</a>().
<p>Example: <a href="simple_dd-example.html#x2825">iconview/simple_dd/main.cpp</a>.
<p>Reimplemented in <a href="qdropevent.html#provides">TQDropEvent</a>.
<h3 class=fn>int <a name="serialNumber"></a>TQMimeSource::serialNumber () const
</h3>
<p> Returns the mime source's globally unique serial number.
