.SH DESCRIPTION
Simple stored-value drag object for arbitrary MIME data.
.PP
When a block of data only has one representation, you can use a QStoredDrag to hold it.
.PP
For detailed information about drag-and-drop, see the QDragObject class.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QStoredDrag::QStoredDrag ( const char * mimeType, QWidget * dragSource = 0, const char * name = 0 )"
Constructs a QStoredDrag. The parameters 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 ()"
Destructs the drag object and frees up all allocated resources.
.SH "QByteArray QStoredDrag::encodedData ( const char * m ) const \fC[virtual]\fR"
Returns the stored data.
.PP
See also setEncodedData().
.SH "const char * QStoredDrag::format ( int i ) const \fC[virtual]\fR"
Reimplemented for internal reasons; the API is not affected.
.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, and 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.
