Member Function Documentation

TQMimeSource::TQMimeSource ()

See also serialNumber().

TQMimeSource::~TQMimeSource () [virtual]

TQByteArray TQMimeSource::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 TQStoredDrag, TQDropEvent, and TQIconDrag.

const char * TQMimeSource::format ( int i = 0 ) const [pure virtual]

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

Reimplemented in TQDropEvent.

bool TQMimeSource::provides ( const char * mimeType ) const [virtual]

If you inherit from TQMimeSource, for consistency reasons it is better to implement the more abstract canDecode() functions such as TQTextDrag::canDecode() and TQImageDrag::canDecode().

Example: iconview/simple_dd/main.cpp.

Reimplemented in TQDropEvent.

int TQMimeSource::serialNumber () const

Returns the mime source's globally unique serial number.
