<hr><h2><a name="details"></a>Detailed Description</h2>
The QImageDrag class provides a drag-and-drop object for transferring images.
<p>
Images are offered to the receiving application in multiple formats,
determined by the <a href="qimage.html#f99ee6">output formats</a>
in Qt.
<p>For detailed information about drag-and-drop, see the <a href="qdragobject.html">QDragObject</a> class.

<h3 class="fn"><a name="b9b20e"></a>QImageDrag::QImageDrag(<a href="qimage.html">QImage</a>image, <a href="qwidget.html">QWidget</a>*dragSource=0, constchar*name=0)</h3>
<p>Constructs an image drag object and sets it to <em>image. dragSource</em>
must be the drag source, <em>name</em> is the object name.
<h3 class="fn"><a name="75ad90"></a>QImageDrag::QImageDrag(<a href="qwidget.html">QWidget</a>*dragSource=0, constchar*name=0)</h3>
<p>Constructs a default text drag object. <em>dragSource</em> must be the drag
source, <em>name</em> is the object name.
<h3 class="fn"><a name="6c448b"></a>QImageDrag::~QImageDrag()</h3>
<p>Destructs the image drag object and frees up all allocated resources.
<h3 class="fn">bool<a name="c35128"></a>QImageDrag::canDecode(const<a href="qmimesource.html">QMimeSource</a>*e) <code>[static]</code></h3>
<p>Returns TRUE if the information in <em>e</em> can be decoded into an image.
<p>See also <a href="#037fd2">decode</a>().
<p>Examples:
<a href="desktop-desktop-cpp.html#QImageDrag::canDecode">desktop/desktop.cpp</a>
<h3 class="fn">bool<a name="b17609"></a>QImageDrag::decode(const<a href="qmimesource.html">QMimeSource</a>*e, <a href="qimage.html">QImage</a>&img) <code>[static]</code></h3>
<p>Attempts to decode the dropped information in <em>e</em>
into <em>img,</em> returning TRUE if successful.
<p>See also <a href="#c35128">canDecode</a>().
<h3 class="fn">bool<a name="037fd2"></a>QImageDrag::decode(const<a href="qmimesource.html">QMimeSource</a>*e, <a href="qpixmap.html">QPixmap</a>&pm) <code>[static]</code></h3>
<p>Attempts to decode the dropped information in <em>e</em>
into <em>pm,</em> returning TRUE if successful.
<p>This is a convenience function that converts
to <em>pm</em> via a <a href="qimage.html">QImage</a>.
<p>See also <a href="#c35128">canDecode</a>().
<p>Examples:
<a href="desktop-desktop-cpp.html#QImageDrag::decode">desktop/desktop.cpp</a>
<h3 class="fn"><a href="qbytearray.html">QByteArray</a><a name="3a6600"></a>QImageDrag::encodedData(constchar*fmt)const <code>[virtual]</code></h3>
<p>Reimplemented for internal reasons; the API is not affected.
<h3 class="fn">constchar*<a name="f361f9"></a>QImageDrag::format(inti)const <code>[virtual]</code></h3>
<p>Reimplemented for internal reasons; the API is not affected.
<p>Reimplemented from <a href="qmimesource.html#17ce96">QMimeSource.</a>
<h3 class="fn">void<a name="02524f"></a>QImageDrag::setImage(<a href="qimage.html">QImage</a>image) <code>[virtual]</code></h3>
<p>Sets the image to be dragged. You will need to call this if you did
not pass the image during construction.
