- /* Session-managment stuff Copyright (C) 1998 Sven Neumann <sven@gimp.org>
-
- I include a short description here on what is done and what problems
- are left:
-
- Since everything saved in sessionrc changes often (with each session?)
- the whole file is rewritten each time the gimp exits. I don't see any
- use in implementing a more flexible scheme like it is used for gimprc.
-
- Right now session-managment is limited to window geometry. Restoring
- openend images is planned, but I'm still not sure how to deal with dirty
- images.
-
- Dialogs are now reopened if the gimp is called with the command-line-option
- --restore-session or if the related entry is set in gimprc.
- Probably there should alternatively be a list of dialogs in the preferences
- that should always be opened on start-up.
-
- Please point me into the right direction to make this work with Gnome-SM.
