From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- .../gnu/java/awt/peer/swing/SwingCheckboxPeer.java | 256 +++++++++++++++++++++ 1 file changed, 256 insertions(+) create mode 100755 libjava/classpath/gnu/java/awt/peer/swing/SwingCheckboxPeer.java (limited to 'libjava/classpath/gnu/java/awt/peer/swing/SwingCheckboxPeer.java') diff --git a/libjava/classpath/gnu/java/awt/peer/swing/SwingCheckboxPeer.java b/libjava/classpath/gnu/java/awt/peer/swing/SwingCheckboxPeer.java new file mode 100755 index 000000000..7080831a2 --- /dev/null +++ b/libjava/classpath/gnu/java/awt/peer/swing/SwingCheckboxPeer.java @@ -0,0 +1,256 @@ +/* SwingCheckboxPeer.java -- A Swing based peer for AWT checkboxes + Copyright (C) 2007 Free Software Foundation, Inc. + +This file is part of GNU Classpath. + +GNU Classpath 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, or (at your option) +any later version. + +GNU Classpath 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.
