Member Function Documentation

QMimeSource::~QMimeSource () [virtual]

Provided to ensure subclasses destruct correctly.

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

Returns the encoded payload of this object, in the specified MIME format.

Subclasses must override this function.

Reimplemented in QDropEvent.

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

Returns the ith format, or NULL.

Examples: qiconview/main.cpp

Reimplemented in QDropEvent.

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

Returns TRUE if the object can provide the data in format mimeType. The default implementation iterates over format().

Note that it is often better to use the more-abstract canDecode() functions such as QTextDrag::canDecode() and QImageDrag::canDecode().

Reimplemented in QDropEvent.
