Author: werner
Date: 2009-08-11 03:20:15 +0200 (Tue, 11 Aug 2009)
New Revision: 5417
Added:
trunk/eda/fped/postscript.c
trunk/eda/fped/postscript.h
Modified:
trunk/eda/fped/Makefile
trunk/eda/fped/gui.c
Log:
- change file save logic to write to a temporary file first, so that we don't
leave an empty/corrupt main file if we crash during saving
- started adding Postscript output
- renamed "Save as KiCad" to "Write KiCad"
- switched from "manual" menu bar creation to GtkItemFactory
Modified: trunk/eda/fped/Makefile
