* [Jogl|Nativewindow|Newt]Common: Align all ↵Sven Gothel2014-01-115-138/+195
| | | | | | | | | | | *Common_GetJNIEnv()/_ReleaseJNIEnv() Methods and Usage / Check arguments .. Since we still don't use inter-module native code sharing, align the JNIEnv get/release methods and usage. Most beneficary here is OSX and the GLDebugMessageHandle, both managed the JVM handle on their own - removed now. Also ensuring that *Common_init(..) is called for all modules on all platforms.

* Bug 935: NEWT PointerIcon: Utilize Toolkit Agnostic PixelFormat and ↵Sven Gothel2014-01-083-29/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Conversion Utilities (Allowing 'arbitrary' PointerIcon data input) Commit fe28bc125429b38cdcd016746081f4a6d521c6fd added the notion of toolkit agnostic PixelFormat and conversion utilities, utilized and further tested by this patch. +++ - PointerIcon is a PixelRectangle and hence holds the decoded data. This allows on-the-fly conversion if required as well as recreation w/o PNG re-decoding. - Using array-backed PointerIcon data where possible, allowing better performance when converting PixelFormat etc. - NEWT Display adds 'createPointerIcon(final IOUtil.ClassResources pngResource...' method to support agnostic PointerIcon creation. - NEWT Display adds methods to allow users to avoid PixelFormat and Buffer NIO type forced conversion: - PixelFormat getNativePointerIconPixelFormat() - boolean getNativePointerIconForceDirectNIO() +++ PNGImage -> PNGPixelRect Deleted: com.jogamp.opengl.util.texture.spi.PNGImage Added: com.jogamp.opengl.util.PNGPixelRect (We hope nobody was using PNGImage directly since it was a service-plugin for TextureIO) PNGPixelRect is a PixelRectangle PNGPixelRect actually is implemented OpenGL agnostic, however - since our PNGJ support lives under package 'jogamp.opengl.util.pngj' it cannot be moved up (yet). PNGPixelRect now handles all PixelFormat for the target format and also added support for grayscale+alpha (2 channels). The latter is force-converted to RGB* - similar to paletted. Further more, PNGPixelRect allows simply passing an OutputStream to write the PNG data. Used by: TextureIO and NEWT +++ - OffscreenSurfaceLayer's setCursor(..) uses the agnostic PixelRectangle instead of a PNG resource. - AWTMisc uses the PixelRectangle to produce the AWT Cursor and converts it to the required format. Hence same pixels are used for NEWT and AWT pointer/cursor icon. - TestGearsES2Newt and NewtAWTReparentingKeyAdapter 'tests' iterate over 3 custom PointerIcon when pressed 'c'. - JOGLNewtAppletBase uses the new custom PointerIcon 'newt/data/crosshair-lumina-trans-32x32.png', which is included in NEWT (213 bytes only). -
* Bug 935: NEWT PointerIcon: Add Toolkit Agnostic PixelFormat and Conversion ↵Sven Gothel2014-01-083-0/+763
| | | | | | | | | | Utilities (Allowing 'arbitrary' PointerIcon data input) To allowing 'arbitrary' PointerIcon data input, i.e. via raw pixels we need to define an agnostic PixelFormat and required conversion utilities. The latter is not hw accelereated (toolkit agnostic), but this shall be expected and satisfying for small amount of 'pixels'.

| | | | | | | | | | OffscreenLayerSurface (OSX CALayer) w/ JAWTWindow Path Add setCursor(..) and hideCursor() to OffscreenLayerSurface interface, impl. in JAWTWindow w/ AWT. This allows an OSX NEWT Window using CALayer (i.e. NewtCanvasAWT) to have setPointerIcon(..) and setPointerVisible(..) functionality!

| | | | | | | | | | | | | | | | | | | | | | | | | | | Pointer Icons - Utilizing JOGL's PNG decoder for all icons, if available. - Application/window icons: - Providing default application/window icons in 16x16 and 32x32 size - NewtFactory.setWindowIcons(..) or property 'newt.window.icons' maybe used to override default icons. - Using icons at application/window instantiation - Display.PointerIcons: - NativeWindow Win32 WindowClass no more references a default cursor in favor of fine grained cursor control [in NEWT] - Display provides create/destroy methods, where display destruction also releases open PointerIcon references. - Window.setPointerIcon(..) sets custom PointerIcon - Implemented Platforms - X11 - Windows - OSX - Manual Test: TestGearsES2NEWT (Press 'c')
* Bug 928 - JAWTWindow's JAWTComponentListener _not_ attached and original ↵Sven Gothel2013-12-181-8/+14
| | | | | | | | | | | | | | | | | | visibility state not restored @ detach Commit ebed9f0322e2a2279a525e04ee3875c9034a7f45 (fix for Bug 906) causes a regression to fix for Bug 816, Bug 849 and Bug 889 (OSX CALayer Positioning and JAWTWindow visibility). The commit adds the JAWTComponentListener instance 'jawtComponentListener' to the component before it's assignment (duh!). +++ Further more, detaching the JAWTComponentListener shall restore the component's original 'local visibility state', which might got overridden by it's 'hierarchyChanged' implementation. +++
* Bug 907 - Refine DummyDispatchThread (DDT) Handling: Proper OO integration ↵Sven Gothel2013-11-296-174/+350
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | in RegisteredClass; Safe DDT Post/WaitForReady handling and error cases ; ... Proper OO integration of DDT in RegisteredClass - DDT is optional to RegisteredClass[Factory], i.e. NEWT without DDT and DummyWindow with DDT. - Using native type DummyThreadContext per DDT passed as DDT handle to java referenced in RegisteredClass - Passing DDT handle to related native methods, if not null use DDT - otherwise work on current thread. The latter impacts CreateDummyWindow0 and DestroyWindow0. Safe DDT Post/WaitForReady handling and error cases ; ... - Wait until command it complete using a 3s timeout - Terminate thread if errors occur and throw an exception +++ Discussion: DDT Native Implementation Due to original code, the DDT is implemented in native code. Usually we should favor running the DDT from a java thread. However, since it's main purpose is _not_ to interact w/ java and the native implementation has less footprint (performance and memory) we shall be OK w/ it for now - as long the implementation IS SAFE.

| | | | | | | | | | | | | | | | | | | | | NW.getLocationOnScreen(..) for X11 and Windows ; Allow unit test to run on all platforms. - Reuse SWTAccessor.isOS_TYPE (public now) - Impl NW.getLocationOnScreen(..) for X11 and Windows reusing existing native code - Allow unit test to run on all platforms. Note: NewtCanvasSWT unit tests require a 'wait for realized' while SWT dispatching. Otherwise the 'sash unit test' will fail since realiziation happens later, at least on X11. Hence extended AWTRobotUtil.waitForRealized(..) to use a 'waitAction' which is used here w/ special SWT dispatch Runnable. AWTRobotUtil.waitForRealized(..) operates on time-delta instead of iteration-counter, allowing above 'waitAction' Runnable. AWTRobotUtil.waitForRealized(..) removed 2nd 'glad.isRealized()' loop ..

| | | | | | | | | | | | | | | | | | | | X11GLXGraphicsConfiguration.GLXFBConfig2GLCapabilities(..) X11GLXGraphicsConfiguration.GLXFBConfig2GLCapabilities(..) ran over all FB configs and for each it grabbed native config values separately. Fetching them in bulk mode saves around 7% of this function's cost. Also reuse XRenderPictFormat instance for 'XRenderDirectFormat XRenderFindVisualFormat(..)' call, saving a few NIO creation cycles w/ StructAccessor. Biggest savior is X11GLXGraphicsConfigurationFactory.chooseGraphicsConfigurationFBConfig()'s fast path w/o chooser and usable 1st FBConfig. Here we only issue 'GLXFBConfig2GLCapabilities(..)' on the first valid entry. Test w/ 50 X11GLXGraphicsConfigurationFactory.chooseGraphicsConfigurationFBConfig() invocations: - pre change: 1.708 ms - post change: 650 ms Time is no spent almost solely on native glXChooseFBConfig (546ms).

| | | | | | | | | | | | JAWTWindow snoops HierarchyEvents for SHOWING_CHANGED to track local component's visibility state as well as it's global visibility state. The later is determined by it's parent's visibility change. If 'removeNotify()' is called, component's visibility is reset to it's local visibility state. Fixes OSX CALayer component's visibility if parent's visibility changes (Bug 729). Fixes continuous GL rendering if parent is invisible (Bug 849).

See unit test for Bug 532: 'TestAWTCardLayoutAnimatorStartStopBug532' Out native 'fixCALayerLayout(..)' takes the visible state as tracked by JAWTWindow's ComponentListener and sets our CALayer (root and sub) hidden state accordingly.
