Member Function Documentation

void BscDNDCustomDEHandler::Clear ( )

virtual

clears the scrap.

Reimplemented from CDataExchangeHandlerFor.

Binds the C implementation class onto its ImplementationID making the C code callable by the application *void BscDNDCustomDEHandler::CreateScrapStorage ( )

virtual

creates storage for the scrap.

Reimplemented from CDataExchangeHandlerFor.

virtual PMFlavor BscDNDCustomDEHandler::GetFlavor ( ) const

inlinevirtual

indicates the type of object this data exchange handler can deal with.

Returns

the flavor supported by the handler

Implements CDataExchangeHandlerFor.

bool16 BscDNDCustomDEHandler::IsEmpty ( ) const

virtual

reports whether the scrap is empty or not.

Returns

kTrue if the scrap is empty, kFalse otherwise.

Reimplemented from CDataExchangeHandlerFor.
