.SH DESCRIPTION
The QImageDrag provides a drag-and-drop object for transferring images.
.PP
Images are offered to the receiving application in multiple formats, determined by the output formats in Qt.
.PP
For detailed information about drag-and-drop, see the QDragObject class.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QImageDrag::QImageDrag ( QImage image, QWidget * dragSource = 0, const char * name = 0 )"
Creates an image drag object and sets it to \fIimage. dragSource\fR must be the drag source, \fIname\fR is the object name.
.SH "QImageDrag::QImageDrag ( QWidget * dragSource = 0, const char * name = 0 )"
Creates a default text 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 all allocated resources.
.SH "bool QImageDrag::canDecode ( const QMimeSource * e ) \fC[static]\fR"
Returns TRUE if the information in \fIe\fR can be decoded into an image.
.PP
See also: decode().
.PP
Examples:
.(l
desktop/desktop.cpp
.)l
.SH "bool QImageDrag::decode ( const QMimeSource * e, QImage & img ) \fC[static]\fR"
Attempts to decode the dropped information in \fIe\fR into \fIimg,\fR returning TRUE if successful.
.PP
See also: canDecode().
.SH "bool QImageDrag::decode ( const QMimeSource * e, QPixmap & pm ) \fC[static]\fR"
Attempts to decode the dropped information in \fIe\fR into \fIpm,\fR returning TRUE if successful.
.PP
This is a convenience function that converts to \fIpm\fR via a QImage.
.PP
See also: canDecode().
.PP
Examples:
.(l
desktop/desktop.cpp
.)l
.SH "void QImageDrag::setImage ( QImage image ) \fC[virtual]\fR"
Sets the image to be dragged.  You will need to call this if you did
not pass the image during construction.
