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.
