From 76bf2e5a7f23def0a3bf2b688791b593ecb283ab Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Mon, 5 Oct 2009 02:54:59 -0700 Subject: GLDrawableFactory Cleanup (-> On- Offscreen and PBuffer) - Base all PBuffer/Offscreen GLDrawable creators on a prev. created 'NativeWindow + SurfaceChangeable' instance. Simplifies implementation path. This also removes the almost cyclic referencing of GLWindow -> OffscreenWindow GLWindow -> Drawable -> NullWindow -> OffscreenWindow Now it is just GLWindow -> OffscreenWindow GLWindow -> Drawable -> OffscreenWindow - createGLDrawable() shall be used for all types now, especially if you want to pass the offscreen NativeWindow and benefit from the surfaceChangedListener etc .. - Add public createOffscreenDrawable(..) - EGLDrawable: - Query surface only if not 0 - [re]create surface only if needed, using 'ownEGL*' flag for destruction only. --- .../javax/media/opengl/GLDrawableFactory.java | 53 ++++++++++------------ .../classes/javax/media/opengl/awt/GLJPanel.java | 9 ++-- 2 files changed, 28 insertions(+), 34 deletions(-) (limited to 'src/jogl/classes/javax') diff --git a/src/jogl/classes/javax/media/opengl/GLDrawableFactory.java b/src/jogl/classes/javax/media/opengl/GLDrawableFactory.java index aade017eb..b7c81cbed 100644 --- a/src/jogl/classes/javax/media/opengl/GLDrawableFactory.java +++ b/src/jogl/classes/javax/media/opengl/GLDrawableFactory.java @@ -177,28 +177,23 @@ public abstract class GLDrawableFactory { public void shutdown() { } + //---------------------------------------------------------------------- + // Methods to create high-level objects + /** - * Returns a GLDrawable according to it's chosen Capabilities. + * Returns a GLDrawable according to it's chosen Capabilities,
