.SH DESCRIPTION
The QStoredDrag class provides a simple stored-value drag object for arbitrary MIME data.
.PP
When a block of data has only one representation, you can use a QStoredDrag to hold it.
.PP
For more information about drag and drop, see the QDragObject class and the drag and drop documentation.

See also Drag And Drop Classes.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QStoredDrag::QStoredDrag ( const char * mimeType, QWidget * dragSource = 0, const char * name = 0 )"
Constructs a QStoredDrag. The \fIdragSource\fR and \fIname\fR are passed to the QDragObject constructor, and the format is set to \fImimeType\fR.
.PP
The data will be unset. Use setEncodedData() to set it.
.SH "QStoredDrag::~QStoredDrag ()"
Destroys the drag object and frees up all allocated resources.
.SH "QByteArray QStoredDrag::encodedData ( const char * m ) const\fC [virtual]\fR"
Returns the stored data. \fIm\fR contains the data's format.
.PP
See also setEncodedData().
.PP
Reimplemented from QMimeSource.
.SH "void QStoredDrag::setEncodedData ( const QByteArray & encodedData )\fC [virtual]\fR"
Sets the encoded data of this drag object to \fIencodedData\fR. The encoded data is what's delivered to the drop sites. It must be in a strictly defined and portable format.
.PP
The drag object can't be dropped (by the user) until this function
has been called.
