+.SH DESCRIPTION
+The QImageDrag class provides a drag and drop object for transferring images.
+.PP
+Images are offered to the receiving application in multiple formats, determined by Qt's output formats.
+.PP
+For more information about drag and drop, see the QDragObject class and the drag and drop documentation.
+.PP
+See also Drag And Drop Classes.
+.SH MEMBER FUNCTION DOCUMENTATION
+.SH "QImageDrag::QImageDrag ( QImage image, QWidget * dragSource = 0, const char * name = 0 )"
+Constructs an image drag object and sets its data to \fIimage\fR. \fIdragSource\fR must be the drag source; \fIname\fR is the object name.
+.SH "QImageDrag::QImageDrag ( QWidget * dragSource = 0, const char * name = 0 )"
+Constructs a default image drag object. \fIdragSource\fR must be the drag source; \fIname\fR is the object name.
+.SH "QImageDrag::~QImageDrag ()"
+Destroys the image drag object and frees up all allocated resources.
+.SH "bool QImageDrag::canDecode ( const QMimeSource * e )\fC [static]\fR"
+Returns TRUE if the information in mime source \fIe\fR can be decoded into an image; otherwise returns FALSE.
+.PP
+See also decode().
+.PP
+Example: desktop/desktop.cpp.
+.SH "bool QImageDrag::decode ( const QMimeSource * e, QImage & img )\fC [static]\fR"
+Attempts to decode the dropped information in mime source \fIe\fR into \fIimg\fR. Returns TRUE if successful; otherwise returns FALSE.
+.PP
+See also canDecode().
+.PP
+Example: desktop/desktop.cpp.
+.SH "bool QImageDrag::decode ( const QMimeSource * e, QPixmap & pm )\fC [static]\fR"
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+.PP
+Attempts to decode the dropped information in mime source \fIe\fR into pixmap \fIpm\fR. Returns TRUE if successful; otherwise returns FALSE.
+.PP
+This is a convenience function that converts to a QPixmap via a QImage.
+.PP
+See also canDecode().
+.SH "void QImageDrag::setImage ( QImage image )\fC [virtual]\fR"
+Sets the image to be dragged to \fIimage\fR. You will need to call
+this if you did not pass the image during construction.
