方法文档编制

QMimeSource.init ( self )

QMimeSource.init ( self , QMimeSource )

QByteArray QMimeSource.encodedData ( self , str)

This method is abstract and should be reimplemented in any sub-class.

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

str QMimeSource.format ( self , int i = 0)

This method is abstract and should be reimplemented in any sub-class.

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

bool QMimeSource.provides ( self , str)

Returns true if the object can provide the data in format mimeType ；否则返回 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().
