Subject: 0032125: Application Framework, OCAF - need to have adequate message if document... 
X-Git-Url: http://git.dev.opencascade.org/gitweb/?a=commitdiff_plain;h=c723a13eee36471898b6e22478cead511e9a3ecf;p=occt-copy.git

0032125: Application Framework, OCAF - need to have adequate message if document cannot be saved due to unrecognized format

A list of storage statuses (PCDM_StoreStatus) is extended for PCDM_SS_UnrecognizedFormat. It is set if
- extension of a document file name is not defined (the extension doesn't correspond to any declared file formats) or
- a storage driver is not found for the document storage format.

Modifications:
CDF_StoreList.cxx: a unique exception is raised in case of the driver is not found by the document format.
PCDM_StoreStatus.hxx: a new enumeration value is added - PCDM_SS_UnrecognizedFormat.
DDocStd_ApplicationCommands.cxx: processing of a new enumeration value by the draw-command.
