/* 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.
|
