From 4cda4b70dbcd21cf57e1e253ddba32b88bcaec18 Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Tue, 8 Feb 2011 06:20:35 +0100 Subject: Move implementation private files from com.jogamp..impl. to jogamp. (1/2) - rename task - com.jogamp.opengl.impl -> jogamp.opengl - com.jogamp.opengl.util.glsl.fixedfunc.impl -> jogamp.opengl.util.glsl.fixedfunc - com.jogamp.nativewindow.impl -> jogamp.nativewindow - com.jogamp.newt.impl -> jogamp.newt This sorts implementation details from the top level, ie skipping the public 'com', allowing a better seperation of public classes and implementation details and also reduces strings. This approach of public/private seperation is also used in the OpenJDK. --- .../windows/wgl/WindowsExternalWGLContext.java | 142 +++++++++++++++++++++ 1 file changed, 142 insertions(+) create mode 100644 src/jogl/classes/jogamp/opengl/windows/wgl/WindowsExternalWGLContext.java (limited to 'src/jogl/classes/jogamp/opengl/windows/wgl/WindowsExternalWGLContext.java') diff --git a/src/jogl/classes/jogamp/opengl/windows/wgl/WindowsExternalWGLContext.java b/src/jogl/classes/jogamp/opengl/windows/wgl/WindowsExternalWGLContext.java new file mode 100644 index 000000000..cfe0a7899 --- /dev/null +++ b/src/jogl/classes/jogamp/opengl/windows/wgl/WindowsExternalWGLContext.java @@ -0,0 +1,142 @@ +/* + * Copyright (c) 2003 Sun Microsystems, Inc.
