+/*  == SENDING EVENTS TO OBJECTS WITH NO WINDOW HANDLE ==
+
+    If the user requested to send the event to a widget with no window,
+    we need to send an event to an object with no hwnd.
+    The way we do that is to send it to the *first* ancestor widget
+    with a window.
+    Then we'll need a way of identifying the child:
+    We'll just keep a list of the most recent events that we have sent,
+    where each entry in the list is identified by a negative value
+    between [-50,-1]. This negative value we will pass on to
+    NotifyWinEvent() as the child id. When the negative value have
+    reached -50, it will wrap around to -1. This seems to be enough
+
+    Now, when the client receives that event, he will first call
+    AccessibleObjectFromEvent() where dwChildID is the special
+    negative value. AccessibleObjectFromEvent does two steps:
+    1. It will first sent a WM_GETOBJECT to the server, asking
+       for the IAccessible interface for the HWND.
+    2. With the IAccessible interface it got hold of it will call
+       acc_getChild where the child id argument is the special
+       negative identifier. In our reimplementation of get_accChild
+       we check for this if the child id is negative. If it is, then
+       we'll look up in our table for the entry that is associated
+       with that value.
+       The entry will then contain a pointer to the QObject /QWidget
+       that we can use to call queryAccessibleInterface() on.
+
+
+    The following figure shows how the interaction between server and
+    client is in the case when the server is sending an event.

+    INTEGRITY framebuffer drivers.
+
+    Note that this class is only available in \l{Qt for INTEGRITY}.
+    Custom screen drivers can be added by subclassing the
+    QScreenDriverPlugin class, using the QScreenDriverFactory class to
+    dynamically load the driver into the application, but there should
+    only be one screen object per application.

+    \class QIdentityProxyModel
+    \brief The QIdentityProxyModel class proxies its source model unmodified
+
+    \ingroup model-view
+
+    QIdentityProxyModel can be used to forward the structure of a source model exactly, with no sorting, filtering or other transformation.
+    This is similar in concept to an identity matrix where A.I = A.
+
+    Because it does no sorting or filtering, this class is most suitable to proxy models which transform the data() of the source model.
+    For example, a proxy model could be created to define the font used, or the background colour, or the tooltip etc. This removes the
+    need to implement all data handling in the same class that creates the structure of the model, and can also be used to create
+    re-usable components.
+
+    This also provides a way to change the data in the case where a source model is supplied by a third party which can not be modified.

     for from Mac OS X with this function being called with the \a caller and
     the \a event.
 
+    For the Cocoa port, If you create an application that inherits QApplication and reimplement
+    this function, you get direct access to all Cocoa Events that Qt receives
+    from Mac OS X with this function being called with the \a caller being 0 and
+    the \a event being an NSEvent pointer:
+
+    NSEvent *e = reinterpret_cast<NSEvent *>(event);
+
     Return true if you want to stop the event from being processed.
     Return false for normal event dispatching. The default
     implementation returns false.
-
-    Cocoa uses a different event system which means this function is NOT CALLED
-    when building Qt against Cocoa. If you want similar functionality subclass
-    NSApplication and reimplement the sendEvent: message to handle all the
-    NSEvents. You also will need to to instantiate your custom NSApplication
-    before creating a QApplication. See \l
-    {http://developer.apple.com/documentation/Cocoa/Reference/ApplicationKit/Classes/NSApplication_Class/Reference/Reference.html}{Apple's
-    NSApplication Reference} for more information.

+    QGenericPluginFactory class will automatically detect the plugin and
+    load the driver into the server application at run-time. See \l
+    {How to Create Qt Plugins} for details.

+
+    In QPA the way to support OpenGL or OpenVG or other technologies that requires a native GL
+    context is through the QPlatformGLContext wrapper.
+
+    There is no factory function for QPlatformGLContexts, but rather only one accessor function.
+    The only place to retrieve a QPlatformGLContext from is through a QPlatformWindow.
+
+    The context which is current for a specific thread can be collected by the currentContext()
+    function. This is how QPlatformGLContext also makes it possible to use the QtOpenGL module
+    withhout using QGLWidget. When using QGLContext::currentContext(), it will ask
+    QPlatformGLContext for the currentContext. Then a corresponding QGLContext will be returned,
+    which maps to the QPlatformGLContext.

+    \brief The QPlatformIntegration class is the entry for WindowSystem specific functionality.
+
+    QPlatformIntegration is the single entry point for windowsystem specific functionality when
+    using the QPA platform. It has factory functions for creating platform specific pixmaps and
+    windows. The class also controls the font subsystem.
+
+    QPlatformIntegration is a singelton class which gets instansiated in the QApplication
+    constructor. The QPlatformIntegration instance do not have ownership of objects it creates in
+    functions where the name starts with create. However, functions which don't have a name
+    starting with create acts as assessors to member variables.
+
+    It is not trivial to create or build a platform plugin outside of the Qt source tree. Therefor
+    the recommended approach for making new platform plugin is to copy an existing plugin inside
+    the QTSRCTREE/src/plugins/platform and develop the plugin inside the source tree.
+
+    The minimal platform integration is the smallest platform integration it is possible to make,
+    which makes it an ideal starting point for new plugins. For a slightly more advanced plugin,
+    consider reviewing the directfb plugin, or the testlite plugin.

+
+    The QPlatformWindow abstraction is used by QWidget for all its top level widgets. It is being
+    created by calling the createPlatformWindow function in the loaded QPlatformIntegration
+    instance.
+
+    QPlatformWindow is used to signal to the windowing system, how Qt persieves its frame.

+
+    Top level QWidgets(tlw) will always have a QPlatformWindow. However, it is not necessary for
+    all tlw to have a QWindowSurface. This is the case for QGLWidget. And could be the case for
+    widgets where some  3.party renders into it.
+
+    The platform specific window handle can be retrieved by the winId function.
+
+    QPlatformWindow is also the way QPA defines how native child windows should be supported
+    through the setParent function.
+
+    The only way to retrieve a QPlatformGLContext in QPA is by calling the glContext() function
+    on QPlatformWindow.

+    \class QPlatformWindowFormat
+    \ingroup painting
+    \since 4.8
+    \brief The QPlatformWindowFormat class specifies the display format of an OpenGL
+    rendering context and if possible attributes of the corresponding QPlatformWindow.
+
+    QWidget has a setter and getter function for QPlatformWindowFormat. These functions can be used
+    by the application programmer to signal what kind of format he wants to the window and glcontext
+    should have. However, it is not always possible to fulfill these requirements. The application
+    programmer should therefore check the resulting QPlatformWindowFormat from QPlatformGLContext
+    to see the format that was actually created.
+
+    A display format has several characteristics:
+    \list
+    \i \link setDoubleBuffer() Double or single buffering.\endlink
+    \i \link setDepth() Depth buffer.\endlink
+    \i \link setRgba() RGBA or color index mode.\endlink
+    \i \link setAlpha() Alpha channel.\endlink
+    \i \link setAccum() Accumulation buffer.\endlink
+    \i \link setStencil() Stencil buffer.\endlink
+    \i \link setStereo() Stereo buffers.\endlink
+    \i \link setDirectRendering() Direct rendering.\endlink
+    \i \link setSampleBuffers() Multisample buffers.\endlink
+    \endlist
+
+    You can also specify preferred bit depths for the color buffer,
+    depth buffer, alpha buffer, accumulation buffer and the stencil
+    buffer with the functions: setRedBufferSize(), setGreenBufferSize(),
+    setBlueBufferSize(), setDepthBufferSize(), setAlphaBufferSize(),
+    setAccumBufferSize() and setStencilBufferSize().
+
+    Note that even if you specify that you prefer a 32 bit depth
+    buffer (e.g. with setDepthBufferSize(32)), the format that is
+    chosen may not have a 32 bit depth buffer, even if there is a
+    format available with a 32 bit depth buffer. The main reason for
+    this is how the system dependant picking algorithms work on the
+    different platforms, and some format options may have higher
+    precedence than others.
+
+    You create and tell a QPlatformWindowFormat object what rendering options you
+    want from an OpenGL rendering context.
+
+    OpenGL drivers or accelerated hardware may or may not support
+    advanced features such as alpha channel or stereographic viewing.
+    If you request some features that the driver/hardware does not
+    provide when you create a QGLWidget, you will get a rendering
+    context with the nearest subset of features.
+
+    There are different ways to define the display characteristics of
+    a rendering context. One is to create a QPlatformWindowFormat and make it the
+    default for the entire application:
+    \snippet doc/src/snippets/code/src_opengl_qgl.cpp 0
+
+    Or you can specify the desired format when creating an object of
+    your QGLWidget subclass:
+    \snippet doc/src/snippets/code/src_opengl_qgl.cpp 1
+
+    After the widget has been created, you can find out which of the
+    requested features the system was able to provide:
+    \snippet doc/src/snippets/code/src_opengl_qgl.cpp 2

+// This is the implementation of the unified toolbar on Mac OS X
+// with the graphics system raster.
+//
+// General idea:
+// -------------
+// We redirect the painting of widgets inside the unified toolbar
+// to a special window surface, the QUnifiedToolbarSurface.
+// We need a separate window surface because the unified toolbar
+// is out of the content view.
+// The input system is the same as for the unified toolbar with the
+// native (CoreGraphics) engine.
+//
+// Execution flow:
+// ---------------
+// The unified toolbar is triggered by QMainWindow::setUnifiedTitleAndToolBarOnMac().
+// It calls QMainWindowLayout::insertIntoMacToolbar() which will
+// set all the appropriate variables (offsets, redirection, ...).
+// When Qt tells a widget to repaint, QWidgetPrivate::drawWidget()
+// checks if the widget is inside the unified toolbar and exits without
+// painting is that is the case.
+// We trigger the rendering of the unified toolbar in QWidget::repaint()
+// and QWidget::update().
+// We keep track of flush requests via "flushRequested" variable. That
+// allow flush() to be a no-op if no repaint occurred for a widget.
+// We rely on the needsDisplay: and drawRect: mecanism for drawing our
+// content into the graphics context.
+//
+// Notes:
+// ------
+// The painting of items inside the unified toolbar is expensive.
+// Too many repaints will drastically slow down the whole application.

+    This enum describes the different levels of hinting that can be applied

+    by the density of pixels.
+
+    \value PreferDefaultHinting Use the default hinting level for the target platform.
+    \value PreferNoHinting If possible, render text without hinting the outlines
+           of the glyphs. The text layout will be typographically accurate and
+           scalable, using the same metrics as are used e.g. when printing.
+    \value PreferVerticalHinting If possible, render text with no horizontal hinting,
+           but align glyphs to the pixel grid in the vertical direction. The text will appear
+           crisper on displays where the density is too low to give an accurate rendering
+           of the glyphs. But since the horizontal metrics of the glyphs are unhinted, the text's
+           layout will be scalable to higher density devices (such as printers) without impacting
+           details such as line breaks.
+    \value PreferFullHinting If possible, render text with hinting in both horizontal and
+           vertical directions. The text will be altered to optimize legibility on the target
+           device, but since the metrics will depend on the target size of the text, the positions
+           of glyphs, line breaks, and other typographical detail will not scale, meaning that a
+           text layout may look different on devices with different pixel densities.
+
+    Please note that this enum only describes a preference, as the full range of hinting levels
+    are not supported on all of Qt's supported platforms. The following table details the effect
+    of a given hinting preference on a selected set of target platforms.

+    \class QGlyphRun
+    \brief The QGlyphRun class provides direct access to the internal glyphs in a font.
+    \since 4.8
+
+    \ingroup text
+    \mainclass
+
+    When Qt displays a string of text encoded in Unicode, it will first convert the Unicode points
+    into a list of glyph indexes and a list of positions based on one or more fonts. The Unicode
+    representation of the text and the QFont object will in this case serve as a convenient
+    abstraction that hides the details of what actually takes place when displaying the text
+    on-screen. For instance, by the time the text actually reaches the screen, it may be represented
+    by a set of fonts in addition to the one specified by the user, e.g. in case the originally
+    selected font did not support all the writing systems contained in the text.
+
+    Under certain circumstances, it can be useful as an application developer to have more low-level
+    control over which glyphs in a specific font are drawn to the screen. This could for instance
+    be the case in applications that use an external font engine and text shaper together with Qt.
+    QGlyphRun provides an interface to the raw data needed to get text on the screen. It
+    contains a list of glyph indexes, a position for each glyph and a font.
+
+    It is the user's responsibility to ensure that the selected font actually contains the
+    provided glyph indexes.
+
+    QTextLayout::glyphRuns() or QTextFragment::glyphRuns() can be used to convert unicode encoded
+    text into a list of QGlyphRun objects, and QPainter::drawGlyphRun() can be used to draw the
+    glyphs.
+
+    \note Please note that QRawFont is considered local to the thread in which it is constructed.
+    This in turn means that a new QRawFont will have to be created and set on the QGlyphRun if it is
+    moved to a different thread. If the QGlyphRun contains a reference to a QRawFont from a different
+    thread than the current, it will not be possible to draw the glyphs using a QPainter, as the
+    QRawFont is considered invalid and inaccessible in this case.

+/*!
+   \class QRawFont
+   \brief The QRawFont class provides access to a single physical instance of a font.
+   \since 4.8
+
+   \ingroup text
+   \mainclass
+
+   \note QRawFont is a low level class. For most purposes QFont is a more appropriate class.
+
+   Most commonly, when presenting text in a user interface, the exact fonts used
+   to render the characters is to some extent unknown. This can be the case for several
+   reasons: For instance, the actual, physical fonts present on the target system could be
+   unexpected to the developers, or the text could contain user selected styles, sizes or
+   writing systems that are not supported by font chosen in the code.
+
+   Therefore, Qt's QFont class really represents a query for fonts. When text is interpreted,
+   Qt will do its best to match the text to the query, but depending on the support, different
+   fonts can be used behind the scenes.
+
+   For most use cases, this is both expected and necessary, as it minimizes the possibility of
+   text in the user interface being undisplayable. In some cases, however, more direct control
+   over the process might be useful. It is for these use cases the QRawFont class exists.
+
+   A QRawFont object represents a single, physical instance of a given font in a given pixel size.
+   I.e. in the typical case it represents a set of TrueType or OpenType font tables and uses a
+   user specified pixel size to convert metrics into logical pixel units. It can be used in
+   combination with the QGlyphRun class to draw specific glyph indexes at specific positions, and
+   also have accessors to some relevant data in the physical font.
+
+   QRawFont only provides support for the main font technologies: GDI and DirectWrite on Windows
+   platforms, FreeType on Symbian and Linux platforms and CoreText on Mac OS X. For other
+   font back-ends, the APIs will be disabled.
+
+   QRawFont can be constructed in a number of ways:
+   \list
+   \o It can be constructed by calling QTextLayout::glyphs() or QTextFragment::glyphs(). The
+      returned QGlyphs objects will contain QRawFont objects which represent the actual fonts
+      used to render each portion of the text.
+   \o It can be constructed by passing a QFont object to QRawFont::fromFont(). The function
+      will return a QRawFont object representing the font that will be selected as response to
+      the QFont query and the selected writing system.
+   \o It can be constructed by passing a file name or QByteArray directly to the QRawFont
+      constructor, or by calling loadFromFile() or loadFromData(). In this case, the
+      font will not be registered in QFontDatabase, and it will not be available as part of
+      regular font selection.
+   \endlist
+
+   QRawFont is considered local to the thread in which it is constructed (either using a
+   constructor, or by calling loadFromData() or loadFromFile()). The QRawFont cannot be moved to a
+   different thread, but will have to be recreated in the thread in question.
+
+   \note For the requirement of caching glyph indexes and font selections for static text to avoid
+   reshaping and relayouting in the inner loop of an application, a better choice is the QStaticText
+   class, since it optimizes the memory cost of the cache and also provides the possibility of paint
+   engine specific caches for an additional speed-up.

+    make sure to sanitize your input, as QLabel tries to guess whether it
+    displays the text as plain text or as rich text. You may want to call
+    setTextFormat() explicitly, e.g. in case you expect the text to be in

     When the content is changed using any of these functions, any
