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/SwingButtonPeer.java | 261 +++++ .../gnu/java/awt/peer/swing/SwingCanvasPeer.java | 64 ++ .../gnu/java/awt/peer/swing/SwingCheckboxPeer.java | 256 +++++ .../gnu/java/awt/peer/swing/SwingComponent.java | 99 ++ .../java/awt/peer/swing/SwingComponentPeer.java | 1136 ++++++++++++++++++++ .../java/awt/peer/swing/SwingContainerPeer.java | 378 +++++++ .../gnu/java/awt/peer/swing/SwingFramePeer.java | 197 ++++ .../gnu/java/awt/peer/swing/SwingLabelPeer.java | 242 +++++ .../gnu/java/awt/peer/swing/SwingListPeer.java | 364 +++++++ .../gnu/java/awt/peer/swing/SwingMenuBarPeer.java | 295 +++++ .../gnu/java/awt/peer/swing/SwingMenuItemPeer.java | 157 +++ .../gnu/java/awt/peer/swing/SwingMenuPeer.java | 284 +++++ .../gnu/java/awt/peer/swing/SwingPanelPeer.java | 67 ++ .../gnu/java/awt/peer/swing/SwingTextAreaPeer.java | 487 +++++++++ .../java/awt/peer/swing/SwingTextFieldPeer.java | 411 +++++++ .../gnu/java/awt/peer/swing/SwingToolkit.java | 181 ++++ .../gnu/java/awt/peer/swing/SwingWindowPeer.java | 99 ++ .../classpath/gnu/java/awt/peer/swing/package.html | 71 ++ 18 files changed, 5049 insertions(+) create mode 100644 libjava/classpath/gnu/java/awt/peer/swing/SwingButtonPeer.java create mode 100644 libjava/classpath/gnu/java/awt/peer/swing/SwingCanvasPeer.java create mode 100755 libjava/classpath/gnu/java/awt/peer/swing/SwingCheckboxPeer.java create mode 100644 libjava/classpath/gnu/java/awt/peer/swing/SwingComponent.java create mode 100644 libjava/classpath/gnu/java/awt/peer/swing/SwingComponentPeer.java create mode 100644 libjava/classpath/gnu/java/awt/peer/swing/SwingContainerPeer.java create mode 100644 libjava/classpath/gnu/java/awt/peer/swing/SwingFramePeer.java create mode 100644 libjava/classpath/gnu/java/awt/peer/swing/SwingLabelPeer.java create mode 100644 libjava/classpath/gnu/java/awt/peer/swing/SwingListPeer.java create mode 100644 libjava/classpath/gnu/java/awt/peer/swing/SwingMenuBarPeer.java create mode 100644 libjava/classpath/gnu/java/awt/peer/swing/SwingMenuItemPeer.java create mode 100644 libjava/classpath/gnu/java/awt/peer/swing/SwingMenuPeer.java create mode 100644 libjava/classpath/gnu/java/awt/peer/swing/SwingPanelPeer.java create mode 100644 libjava/classpath/gnu/java/awt/peer/swing/SwingTextAreaPeer.java create mode 100644 libjava/classpath/gnu/java/awt/peer/swing/SwingTextFieldPeer.java create mode 100644 libjava/classpath/gnu/java/awt/peer/swing/SwingToolkit.java create mode 100644 libjava/classpath/gnu/java/awt/peer/swing/SwingWindowPeer.java create mode 100644 libjava/classpath/gnu/java/awt/peer/swing/package.html (limited to 'libjava/classpath/gnu/java/awt/peer/swing') diff --git a/libjava/classpath/gnu/java/awt/peer/swing/SwingButtonPeer.java b/libjava/classpath/gnu/java/awt/peer/swing/SwingButtonPeer.java new file mode 100644 index 000000000..1a42fc953 --- /dev/null +++ b/libjava/classpath/gnu/java/awt/peer/swing/SwingButtonPeer.java @@ -0,0 +1,261 @@ +/* SwingButtonPeer.java -- A Swing based peer for AWT buttons + Copyright (C) 2006, 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.

Swing based AWT peers.

+

This package defines an abstract set of AWT peers that is based on Swing + widgets. This can be used as an implementation base for peer implementors + who don't have access to native widgets or who want to build a quick + prototype of a peer set without implementing all of the AWT widgets. +

+

An actual implementation would have to provide the following: +
