<hr><a name="details"></a><h2>Detailed Description</h2>
<p> The QImageDrag class provides a drag and drop object for
transferring images.
<p>
<p> Images are offered to the receiving application in multiple
formats, determined by Qt's <a href="qimage.html#outputFormats">output
formats</a>.
<p> For more information about drag and drop, see the <a href="qdragobject.html">QDragObject</a>
class and the <a href="dnd.html">drag and drop documentation</a>.
<p>See also <a href="draganddrop.html">Drag And Drop Classes</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="QImageDrag"></a>QImageDrag::QImageDrag ( <a href="qimage.html">QImage</a> image, <a href="qwidget.html">QWidget</a> * dragSource = 0, const char * name = 0 )
</h3>
Constructs an image drag object and sets its data to <em>image</em>. <em>dragSource</em> must be the drag source; <em>name</em> is the object name.
<h3 class=fn><a name="QImageDrag-2"></a>QImageDrag::QImageDrag ( <a href="qwidget.html">QWidget</a> * dragSource = 0, const char * name = 0 )
</h3>
Constructs a default image drag object. <em>dragSource</em> must be the
drag source; <em>name</em> is the object name.
<h3 class=fn><a name="~QImageDrag"></a>QImageDrag::~QImageDrag ()
</h3>
Destroys the image drag object and frees up all allocated
resources.
<h3 class=fn>bool <a name="canDecode"></a>QImageDrag::canDecode ( const <a href="qmimesource.html">QMimeSource</a> * e )<tt> [static]</tt>
</h3>
Returns TRUE if the information in mime source <em>e</em> can be decoded
into an image; otherwise returns FALSE.
<p> <p>See also <a href="#decode">decode</a>().
<p>Example: <a href="desktop-example.html#x1731">desktop/desktop.cpp</a>.
<h3 class=fn>bool <a name="decode"></a>QImageDrag::decode ( const <a href="qmimesource.html">QMimeSource</a> * e, <a href="qimage.html">QImage</a> & img )<tt> [static]</tt>
</h3>
Attempts to decode the dropped information in mime source <em>e</em>
into <em>img</em>. Returns TRUE if successful; otherwise returns FALSE.
<p> <p>See also <a href="#canDecode">canDecode</a>().
<p>Example: <a href="desktop-example.html#x1732">desktop/desktop.cpp</a>.
<h3 class=fn>bool <a name="decode-2"></a>QImageDrag::decode ( const <a href="qmimesource.html">QMimeSource</a> * e, <a href="qpixmap.html">QPixmap</a> & pm )<tt> [static]</tt>
</h3>
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> Attempts to decode the dropped information in mime source <em>e</em>
into pixmap <em>pm</em>. Returns TRUE if successful; otherwise returns
FALSE.
<p> This is a convenience function that converts to a <a href="qpixmap.html">QPixmap</a> via a
<a href="qimage.html">QImage</a>.
<p> <p>See also <a href="#canDecode">canDecode</a>().
<h3 class=fn>void <a name="setImage"></a>QImageDrag::setImage ( <a href="qimage.html">QImage</a> image )<tt> [virtual]</tt>
</h3>
Sets the image to be dragged to <em>image</em>. You will need to call
this if you did not pass the image during construction.
