lost. After the data is loaded, the insertion cursor is positioned at
the first character.
The widget argument specifies the DtEditor widget ID.
The fileName argument is the pathname of the file relative to the local
system.
For a complete definition of the DtEditor widget and its associated
resources, see DtEditor(3).

DtEDITOR_NO_ERRORS
The file is readable and writable.
DtEDITOR_READ_ONLY_FILE
