From 675a2a355ef15825b5998adc89a69d0958a0e2c0 Mon Sep 17 00:00:00 2001 From: Ray Strode Date: Thu, 13 Dec 2007 10:06:26 -0500 Subject: [PATCH] Add new chooser widget Since it takes a lot of code to deal with the whole model/view split of a tree view, it's probably better to abstract that work out into one unified "chooser" widget. --- gui/simple-greeter/gdm-chooser-widget.c | 1607 +++++++++++++++++++++++++++++++ gui/simple-greeter/gdm-chooser-widget.h | 102 ++ 2 files changed, 1709 insertions(+), 0 deletions(-) create mode 100644 gui/simple-greeter/gdm-chooser-widget.c create mode 100644 gui/simple-greeter/gdm-chooser-widget.h diff --git a/gui/simple-greeter/gdm-chooser-widget.c b/gui/simple-greeter/gdm-chooser-widget.c new file mode 100644 index 0000000..64186a2 --- /dev/null +++ b/gui/simple-greeter/gdm-chooser-widget.c @@ -0,0 +1,1607 @@ +/* -*- Mode: C; tab-width: 8; indent-tabs-mode: nil; c-basic-offset: 8 -*- + * + * Copyright (C) 2007 Ray Strode + * Copyright (C) 2007 William Jon McCann + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * 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.
