Deriving from wxFilterOutput/InputStream
Posted: Fri Jul 28, 2006 7:29 am
When implementing a full-fledged stream derived from wxFilterOutput/InputStream, what functions should it override? Obviously OnSysRead and OnSysWrite, but what about seeking, telling, and errors? GetLength and GetSize? Do the functions it doesn't override just get called on the parent-stream (m_parent_i/o_stream) or do they give an error, or just nothing?
