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.
