An abstract piece of formatted data.
.PP
Drag-and-drop and clipboard use this abstraction.

.SH MEMBER FUNCTION DOCUMENTATION
.SH "QMimeSource::~QMimeSource () \fC[virtual]\fR"
Provided to ensure subclasses destruct correctly.
.SH "QByteArray QMimeSource::encodedData ( const char * ) const \fC[virtual]\fR"
Returns the encoded payload of this object, in the specified MIME format.
.PP
Subclasses must reimplement this function.
.PP
Reimplemented in QDropEvent.
.SH "const char * QMimeSource::format ( int i = 0 ) const \fC[virtual]\fR"
Returns the \fIith\fR format, or NULL.
.PP
Reimplemented in QImageDrag, QTextDrag, QStoredDrag and QDropEvent.
.SH "bool QMimeSource::provides ( const char * mimeType ) const \fC[virtual]\fR"
Returns TRUE if the object can provide the data in format \fImimeType.\fR The default implementation iterates over format().
.PP
Note that it is often better to use the more-abstract canDecode() functions such as QTextDrag::canDecode() and QImageDrag::canDecode().
.PP
Reimplemented in QDropEvent.
