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