# qmimesource(3qt)

Abstraction of objects which provide formatted data of a certain MIME type

## NAME

QMimeSource - Abstraction of objects which provide formatted data of a certain MIME type

## SYNOPSIS

`#include <qmime.h>`

Inherited by QDragObject and QDropEvent.

### Public Members

**QMimeSource ()**\
 **virtual ~QMimeSource ()**\
 **virtual const char \* format ( int i = 0 ) const = 0**\
 **virtual bool provides ( const char \* mimeType ) const**\
 **virtual QByteArray encodedData ( const char \* ) const = 0**\
 **int serialNumber () const**\

## DESCRIPTION

The QMimeSource class is an abstraction of objects which provide formatted data of a certain MIME type.

Drag-and-drop and clipboard use this abstraction.

See also IANA list of MIME media types, Drag And Drop Classes, Input/Output and Networking, and Miscellaneous Classes.

## MEMBER FUNCTION DOCUMENTATION

## QMimeSource::QMimeSource ()

Constructs a mime source and assigns a globally unique serial number to it.

See also serialNumber().

## QMimeSource::~QMimeSource ()` [virtual]`

Provided to ensure that subclasses destroy themselves correctly.

## QByteArray QMimeSource::encodedData ( const char \* ) const` [pure virtual]`

Returns the encoded data of this object in the specified MIME format.

Subclasses must reimplement this function.

Reimplemented in QStoredDrag, QDropEvent, and QIconDrag.

## const char \* QMimeSource::format ( int i = 0 ) const` [pure virtual]`

Returns the *i*-th supported MIME format, or 0.

Reimplemented in QDropEvent.

## bool QMimeSource::provides ( const char \* mimeType ) const` [virtual]`

Returns TRUE if the object can provide the data in format *mimeType*; otherwise returns FALSE.

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().

Example: iconview/simple\_dd/main.cpp.

Reimplemented in QDropEvent.

## int QMimeSource::serialNumber () const

Returns the mime source's globally unique serial number.
