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/ClasspathDesktopPeer.java | 301 +++ .../gnu/java/awt/peer/ClasspathFontPeer.java | 865

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: +

    +
  • A concrete implementation of {@link java.awt.Toolkit}, possibly based + on {@link SwingToolkit}. This implementation must provide all the missing + methods of the SwingToolkit.
    • +
  • Concrete implementations of {@link java.awt.peer.DialogPeer}, + {@link java.awt.peer.FramePeer} and {@link java.awt.peer.WindowPeer}, + ideally based on their SwingXXXPeer counterparts. + Some methods must be specially + overridden in those peers to provide useful functionality, like + getLocationOnScreen(). See the API documentation for more + details
    • +
  • An implementation of {@link java.awt.Image}. These must be provided by + the toplevel component peers.
    • +
  • An implementation of {@link java.awt.Graphics}. This must also be + provided by the toplevel peers.
    • +
  • An implementation of {@link java.awt.Font}. This must be + provided by the toolkit.
