|
|
<h3 class=fn><a name="QMimeSource"></a>QMimeSource::QMimeSource ()
|
||
|
|
</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="~QMimeSource"></a>QMimeSource::~QMimeSource ()<tt> [virtual]</tt>
|
||
|
|
</h3>
|
||
|
|
Provided to ensure that subclasses destroy themselves correctly.
|
||
|
|
|
||
|
|
<h3 class=fn><a href="qbytearray.html">QByteArray</a> <a name="encodedData"></a>QMimeSource::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">QStoredDrag</a>, <a href="qdropevent.html#encodedData">QDropEvent</a>, and <a href="qicondrag.html#encodedData">QIconDrag</a>.
|
||
|
|
<h3 class=fn>const char * <a name="format"></a>QMimeSource::format ( int 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">QDropEvent</a>.
|
||
|
|
<h3 class=fn>bool <a name="provides"></a>QMimeSource::provides ( const char * 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 QMimeSource, for consistency reasons it is
|
||
|
|
better to implement the more abstract canDecode() functions such
|
||
|
|
as <a href="qtextdrag.html#canDecode">QTextDrag::canDecode</a>() and <a href="qimagedrag.html#canDecode">QImageDrag::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">QDropEvent</a>.
|
||
|
|
<h3 class=fn>int <a name="serialNumber"></a>QMimeSource::serialNumber () const
|
||
|
|
</h3>
|
||
|
|
|
||
|
|
<p> Returns the mime source's globally unique serial number.
