Detailed Description

The QMimeSource class is an abstraction of objects that provided formatted data of a certain MIME type.

The preferred approach to drag and drop is to use QDrag in conjunction with QMimeData. See Drag and Drop for details.

See also QMimeData and QDrag.

Member Function Documentation

QMimeSource::~QMimeSource ()   [virtual]

Destroys the MIME source.

QByteArray QMimeSource::encodedData ( const char * format ) const   [pure virtual]

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

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

Returns the (i - 1)-th supported MIME format, or 0.

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().
