From 8a16d590fe2c739badbabe4906cbe9d60b20e2b9 Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Sat, 12 Nov 2011 16:15:54 +0100 Subject: OS X Layered View Part8: Generalize OffscreenLayerSurface ; Use local JAWT instance ; Applet's on OS X are working Generalize OffscreenLayerSurface - Using new OffscreenLayerSurface allows using this functionality in a clean manner, ie. no 'dirty' usage of MacOSXJAWTWindow in a JOGL GL class. - 'Promoting' OffscreenLayerSurface functionality to JAWTWindow and it's handling to GLDrawableFactoryImpl::createGLDrawable(). - Move MacOSXCGLDrawableFactory's "MacOSXJAWTWindow getLayeredSurfaceHost(NativeSurface surface)" to NativeWindowFactory "OffscreenLayerSurface getOffscreenLayerSurface(NativeSurface surface, boolean ifEnabled)" Use local JAWT instance - Only w/ a local JAWT instance per JAWTWindow it is possible to switch between offscreen-layer and onscreen. We also have to determing offscreen-layer lazy at surface lock, since only at that time we have knowledge whether it's an Applet or not. +++ ContextUpdater: Use local pthread mutex, add DEBUG output JAWTWindow/NewtCanvasAWT: Adding methods to request offscreen-layer-surface (if supported), besides 'if applet' this may trigger the new functionality. +++ Applet's on OS X are working: - OS X 10.6.4 - Safari: - Hangs for a while at start .. whole screen freezes .. approx. 10s - Sometimes crashes when Applet stops - after all our resources are released! - Keyboard input isn't assigned sometimes. - Otherwise .. works well, incl. offscreen/onscreen parenting - Firefox 8.0: - Hangs for a while at start .. whole screen freezes .. approx. 10s - Sometimes crashes when Applet stops - after all our resources are released! - Keyboard input is never assigned. - Otherwise .. works well, incl. offscreen/onscreen parenting - OS X 10.7 - Safari: - Sometimes crashes when Applet stops - after all our resources are released! - Keyboard input isn't assigned sometimes. - Otherwise .. works well, incl. offscreen/onscreen parenting - Firefox 8.0: - Sometimes crashes when Applet stops - after all our resources are released! - Keyboard input is never assigned. - Otherwise .. works well, incl. offscreen/onscreen parenting --- .../media/nativewindow/NativeWindowFactory.java | 29 ++++++++++++ .../media/nativewindow/OffscreenLayerSurface.java | 51 ++++++++++++++++++++++ 2 files changed, 80 insertions(+) create mode 100644 src/nativewindow/classes/javax/media/nativewindow/OffscreenLayerSurface.java (limited to 'src/nativewindow/classes/javax') diff --git a/src/nativewindow/classes/javax/media/nativewindow/NativeWindowFactory.java b/src/nativewindow/classes/javax/media/nativewindow/NativeWindowFactory.java index 60ce07f09..b6c850098 100644 --- a/src/nativewindow/classes/javax/media/nativewindow/NativeWindowFactory.java +++ b/src/nativewindow/classes/javax/media/nativewindow/NativeWindowFactory.java @@ -475,4 +475,33 @@ public abstract class NativeWindowFactory { NativeWindow.
