From d1b458f248e476ff70b3378e4b4e7ea620ca0c75 Mon Sep 17 00:00:00 2001 From: Kenneth Russel Date: Thu, 4 Jan 2007 05:38:43 +0000 Subject: Moved J2DTextureRenderer and J2DOverlay into their own sub-package and dropped the prefixes on the suggestion of Chris Campbell. No other changes to these classes. Added com.sun.opengl.util.j2d to the javadoc generation. Updated demos. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/../svn-server-sync/jogl-demos/trunk@195 3298f667-5e0e-4b4a-8ed4-a3559d26a5f4 --- src/demos/j2d/TestJ2DOverlay.java | 204 --------------------------------- src/demos/j2d/TestJ2DRenderer.java | 203 -------------------------------- src/demos/j2d/TestOverlay.java | 204 +++++++++++++++++++++++++++++++++ src/demos/j2d/TestTextureRenderer.java | 203 ++++++++++++++++++++++++++++++++ 4 files changed, 407 insertions(+), 407 deletions(-) delete mode 100755 src/demos/j2d/TestJ2DOverlay.java delete mode 100755 src/demos/j2d/TestJ2DRenderer.java create mode 100755 src/demos/j2d/TestOverlay.java create mode 100755 src/demos/j2d/TestTextureRenderer.java (limited to 'src') diff --git a/src/demos/j2d/TestJ2DOverlay.java b/src/demos/j2d/TestJ2DOverlay.java deleted file mode 100755 index a3104ac..0000000 --- a/src/demos/j2d/TestJ2DOverlay.java +++ /dev/null @@ -1,204 +0,0 @@ -/* - * Copyright (c) 2006 Sun Microsystems, Inc.
