.SH DESCRIPTION
The QMimeSource class is an abstraction of objects which provide formatted data of a certain MIME type.
.PP
Drag-and-drop and clipboard use this abstraction.
.PP
See also IANA list of MIME media types, Drag And Drop Classes, Input/Output and Networking, and Miscellaneous Classes.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QMimeSource::QMimeSource ()"
Constructs a mime source and assigns a globally unique serial number to it.
.PP
See also serialNumber().
.SH "QMimeSource::~QMimeSource ()\fC [virtual]\fR"
Provided to ensure that subclasses destroy themselves correctly.
.SH "QByteArray QMimeSource::encodedData ( const char * ) const\fC [pure virtual]\fR"
Returns the encoded data of this object in the specified MIME format.
.PP
Subclasses must reimplement this function.
.PP
Reimplemented in QStoredDrag, QDropEvent, and QIconDrag.
.SH "const char * QMimeSource::format ( int i = 0 ) const\fC [pure virtual]\fR"
Returns the \fIi\fR-th supported MIME format, or 0.
.PP
Reimplemented in 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; otherwise returns FALSE.
.PP
If you inherit from QMimeSource, for consistency reasons it is better to implement the more abstract canDecode() functions such as QTextDrag::canDecode() and QImageDrag::canDecode().
.PP
Example: iconview/simple_dd/main.cpp.
.PP
Reimplemented in QDropEvent.
.SH "int QMimeSource::serialNumber () const"
Returns the mime source's globally unique serial number.
