## 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 reimplement this function.

Reimplemented in QDropEvent.

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

Returns the ith format, or NULL.

Reimplemented in QTextDrag, QStoredDrag, QDropEvent and QImageDrag.

### 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.
