* Bug 1161 - Fix Canvas resize stops the rendering in Mac OS X (mostly from ↵Sven Gothel2015-07-281-2/+3
| | | | | | | | | | | | | | | | | | | | | | WebStart) Root cause: JAWTWindow's JAWTComponentListener 'isShowing' state is initialized while attaching it on-thread and updated via hierarchy-changed event. JAWTComponentListener attachment to the component is issued at JAWTWindow's creation but on the AWT-EDT, hence it may happen at a later time. In this bug scenario, it happens very late, so that the hierarchy-changed event is missed and 'isShowing' is never set to 'true'. Solution is to update 'isShowing' state on the actual AWT-EDT when attaching to the component. Also make 'isShowing' volatile.
* Bug 1181 - JOGL WebStart Applications using GLCanvas/AWT may Deadlock by two ↵Sven Gothel2015-07-274-23/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | AWT-EDT on Java >= 1.8.0_45 Root cause: - AWT Toolkit global Lock Our locking scheme (AWT-EDT-1): - Surface Lock - sun.awt.SunToolkit.awtLock() - Component.getGraphicsConfiguration() -> synchronized(Component.getTreeLock()) Other AWT-EDT-2 by Webstart: - synchronized(Component.getTreeLock()) - sun.awt.SunToolkit.awtLock() Results in a deadlock. Solution: - Issue Component.getGraphicsConfiguration() before awtLock(), where Component.getGraphicsConfiguration() is being used to detect possible reconfiguration. - Also use updated AWTGraphicsConfiguration's GraphicsConfiguration if no 'new' detection is required.
* Bug 1184 - JOGL AWT Canvas Components don't update AWTGraphicsConfiguration ↵Sven Gothel2015-07-272-14/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | when reconfigured. JOGL AWT Components, e.g. GLCanvas or NewtCanvasAWT, may be reconfigured by moving them to another display/monitor or by other means. Since AWT has no means to notify the user code via an event, JOGL components usually determine the reconfiguration via the override 'GraphicsConfiguration getGraphicsConfiguration()'. GLCanvas is sensible to this reconfiguration, however its AWTGraphicsConfiguration (owned via JAWTWindow) is not changed. Implement reconfiguration detection for all JOGL AWT Components and update the AWTGraphicsConfiguration if required. For now, constraint reconfiguration on GraphicsDevice change as currently implemented in GLCanvas. The updated AWTGraphicsConfiguration allows using the updated GraphicsDevice as it might be required for further information, e.g. pixel-scale on OSX.
* Expand bitmasks in SWTAccessor GTK_VERSION methodrhatcher2015-07-101-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | SWTAccessor's GTK_VERSION method accepts a single int argument. The argument is interpreted as a bit-packed version number with the apparent intent that the three least significant bytes of the int version number are the major, minor, and micro version number components. The code that extracts these three components from the int argument was using four-bit mask 0x0f instead of eight-bit mask 0xff, and therefore was discarding the four most significant bits of each component. This caused any component greater than 15 to lose information. For example, a component whose value should have been 20 would end up as 4. The version number is used in comparisons in a static initializer to determine how to retrieve references to Method objects via reflection. One such comparison decides whether to retrieve a reference to method GTK_WIDGET_WINDOW or method gtk_widget_get_window. The problem initially presented itself after an attempt to use JOGL with SWT 4.527 and GTK 2.20.1 because this version of SWT removed the GTK_WIDGET_WINDOW method. Due to the bug SWTAccessor believed the GTK version was 2.4.1 instead of 2.20.1, so the code attempted to find GTK_WIDGET_WINDOW instead of gtk_widget_get_window. Because this method was no longer there a runtime exception was raised.
* Bug 1148 - OSX MonitorDevice: Use unique and native deviceID instead of indexSven Gothel2015-03-213-78/+23
| | | | | | | | | | | | | Adopt to bug 1147, commit 2c88b6dfd4eb7e2cd9a50fa48e08ecafc980931a. Using the native unique deviceID makes monitor identification more robust. This also allows us simplify displayID -> NSScreen-idx -> MonitorDevice into displayID -> MonitorDevice and to survive a primary monitor change.

* Bug 1120 - Refine HiDPI Support ( Part-2 ) (API CHANGE)Sven Gothel2015-01-2710-312/+392
| | | | | | | | | | | | | | | | | | | | | | - Use float[2] for pixel-scale. Utilize simple integer rounding: int-pixel-units = (int) ( int-window-units * pixel-scale + 0.5f ) - Provide minimum and maximum allowed pixel-scale values to be set by platform, supporting generic pixel-scale validation. - Remove 'OSXUtil.GetPixelScale(final RectangleImmutable r, final int[] screenIndexOut)', implementation for all platforms would cause huge redundancy of Screen and MonitorDevice code (duplication of NEWT). - instead, add 'float[2] pixelScale' to NEWT's MonitorDevice - Detect change of pixel-scale and propagate accordingly. This allows GLCanvas, GLJPanel and NewtCanvasAWT instances to be dragged between monitor devices w/ different pixel-scale. - OSX: Handle native triggered reshape events off-thread to avoid EDT congestion due to locked window when consuming deferred events on EDT.

* Bug 1107 - Refine PixelFormat, GLPixelBuffer and ↵Sven Gothel2014-12-065-237/+1040
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DirectDataBufferInt/BufferedImageInt - PixelFormat Refine definition allowing complete format conversion by its attributes instead of static 'knowledge'. - PixelFormat has_a *new* PixelFormat.Composition - PixelFormat.Composition contains all pixel component layout information as required for inspection and conversion. Component names are enumerated via PixelFormat.CType. - PixelFormatUtil.convert(..) utilizes generic conversion based on PixelFormat.Composition rather static type mapping. However, a int32 RGBA static conversion is still supported for performance. Utilizes Bitstream for varying pixel component bit-width. - Complete w/ hashCode() and equals(..) - GLPixelBuffer - Take 'pack' mode into account when determine GLPixelAttributes, i.e. on GLES pack=true (e.g. glReadPixel) only RGBA is guaranteed to work. Hence querying GLPixelAttributes requires the GLProfile, PixelFormat and pack mode. - Complete GLPixelAttributes conversions from PixelFormat or GL format/data-type, while taking GL data-type into account, as well as pack-mode. - Complete w/ hashCode() and equals(..) - SingletonGLPixelBufferProvider queries singleton GLPixelBuffer via - PixelFormat.Composition hostPixelComp, - GLPixelAttributes pixelAttributes, - boolean pack which comprise a unique key, allowing the implementation to utilize a hash map. This is implemented in AWTSingletonGLPixelBufferProvider. This allows distinct singleton GLPixelBuffer for different host PixelFormat (conversion) and GLPixelAttributes (depending on GLProfile). - Removes field 'componentCount' which was 'hacked in' to pass information about an optional host memory layout. Implementations utilizing conversion, e.g. AWTGLPixelBuffer, can implement GLPixelBufferProvider's 'PixelFormat.Composition getHostPixelComp(final GLProfile glp, final int componentCount)' and manage such implementation details, see use-case GLJPanel. - DirectDataBufferInt/BufferedImageInt: Expose underlying NIO ByteBuffer - AWTMisc.createCursor(..) uses DirectDataBufferInt.BufferedImageInt exposed NIO ByteBuffer, allowing to use generic PixelFormatUtil.convert(..).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | crashes the app The 'magic' MyNSOpenGLContext::dealloc (MacOSXWindowSystemInterface-calayer.m) of force destroying the underlying CGLContextObj of it's associated NSOpenGLContext as introduced as a remedy of Bug 691 is plain wrong. It was added in commit f6e6fab2a7ddfb5c9b614cb072c27ff697629161 to mitigate the experience behavior of delayed GL context destruction when creating/destroying them multiple times as exposed in unit test TestGLCanvasAddRemove01SwingAWT. While this 'hack' worked for some reason on some OSX versions, it caused a 'access/modify after free' issue exposed under some circumstances and crashes the application. The actual culprit of the delayed GL context destruction is different. The offthread CALayer detachment and hence final destruction issued on the main-thread is _not_ issued immediately due to some referencing holding by NSApp. Issuing an empty event on the NSApp (thread) will wake up the thread and release claimed resources. This has been found while realizing that the GL context are released if the mouse is being moved (duh!). This issue is also known when triggering stop on the NSApp (NEWT MainThread), same remedy has been implemented here for a long time.
