From b06cdfab92313ca7b1ce9a88ccb0ffba33cb17ab Mon Sep 17 00:00:00 2001 From: Matthew Barnes Date: Wed, 19 Nov 2008 01:39:19 +0000 Subject: Progress update: - Tighter integration of GalViewInstance and EShellView. - EBinding. Stolen from ExoBinding. Lets you bind GObject properties together to automatically keep their values in sync. This is a godsend. Added to e-util, but might even deserve a place in libedataserver. - EShellSettings. This is the concept I blogged about. Already started ripping apart em-mailer-prefs.c. Others to follow. Any place where we're monitoring GConf keys is a target. - Incremental progress on the calender and mailer. Got EMFolderView somewhat working, but I think I'll be killing off EMFolderBrowser. svn path=/branches/kill-bonobo/; revision=36795 --- e-util/e-binding.h | 107 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 107 insertions(+) create mode 100644 e-util/e-binding.h (limited to 'e-util/e-binding.h') diff --git a/e-util/e-binding.h b/e-util/e-binding.h new file mode 100644 index 0000000000..2cced75920 --- /dev/null +++ b/e-util/e-binding.h @@ -0,0 +1,107 @@ +/* + * e-binding.h + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2 of the License, or (at your option) version 3. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
