+These examples show how to take advantage of features specifically designed
+for use on systems with limited resources, specialized hardware, and small
+screens.
+
+
+The example launcher provided with Qt can be used to explore each of the
+examples in this directory.
+
+Documentation for these examples can be found via the Tutorial and Examples
+link in the main Qt documentation.
+
+
+Finding the Qt Examples and Demos launcher
+==========================================
+
+On Windows:
+
+The launcher can be accessed via the Windows Start menu. Select the menu
+entry entitled "Qt Examples and Demos" entry in the submenu containing
+the Qt tools.
+
+On Mac OS X:
+
+For the binary distribution, the qtdemo executable is installed in the
+/Developer/Applications/Qt directory. For the source distribution, it is
+installed alongside the other Qt tools on the path specified when Qt is
+configured.
+
+On Unix/Linux:
+
+The qtdemo executable is installed alongside the other Qt tools on the path
+specified when Qt is configured.
+
+On all platforms:
+
+The source code for the launcher can be found in the demos/qtdemo directory
+in the Qt package. This example is built at the same time as the Qt libraries,
+tools, examples, and demonstrations.

+  \class QAhiGLScreen
+
+  \brief The QAhiGLScreen class is the screen driver for the ATI handheld device interface.
+
+  QAhiGLScreen is implemented with the d-pointer pattern. That is,
+  the only data member the class contains is a pointer called d_ptr,
+  which means data pointer. It points to an instance of a private
+  class called QAhiGLScreenPrivate, where all the screen driver's
+  context data members are defined. The d-pointer pattern is used
+  so that changes can be made to the screen driver's context data
+  members without destroying the binary compatibility of the public
+  screen driver class.
+
+  The pure virtual functions found in the base class QScreen are
+  listed below. All must have implementations in any screen driver
+  class derived from QScreen. All are impemented in this example,
+  except for setMode(), which has only been given a stub
+  implementation to satisfy the compiler.
+
+  bool connect(const QString & displaySpec);
+  void disconnect();
+  bool initDevice();
+  void setMode(int width, int height, int depth);
+
+  The stub implementation of setMode() is not meant to indicate
+  setMode() can be ignored in your own screen driver class. It was
+  simply decided not to provide a fully implemented screen driver
+  class for the example, which would normally be tailored to your
+  device's specific requirements.
+
+  The base class QGLScreen has only one pure virtual function,
+  hasOpenGL(), which must return true if your screen driver class
+  supports OpenGL.

+    \class QAhiGLWindowSurface
+    \preliminary
+    \internal
+
+    \brief The QAhiGLWindowSurface class provides the drawing area
+    for top-level windows using OpenGL for drawing on an ATI handheld
+    device.
+
+    In \l{Qt for Embedded Linux}, the default behavior for each client is to
+    render widgets into an area of memory. The server then displays
+    the contents of that memory on the screen. For ATI handheld
+    devices using OpenGL, QAhiGLWindowSurface is the window surface
+    class that allocates and manages the memory areas in the clients
+    and the server.
+
+    When a screen update is required, the server runs through all the
+    top-level windows that intersect with the region being updated,
+    ensuring that the clients have updated their window surfaces. Then
+    the server uses the screen driver to copy the contents of the
+    affected window surfaces into its composition and then display the
+    composition on the screen.
+
+    \tableofcontents
+
+    \section1 Pure Virtual Functions
+
+    There are two window surface instances for each top-level window.
+    One is used by the application when drawing a window, and the
+    other is used by the server application to make its copy for
+    building a window composition to send to the screen.
+
+    The key() function is implemented to uniquely identify this window
+    surface class as "ahigl", and the isValid() function is
+    implemented to determine whether the associated window is still
+    acceptable for representation by this window surface class.  It
+    must either be a window using an \l {QGLWidget} {OpenGL widget},
+    or it must be a window whose frame is no bigger than 256 x 256.
+
+    The setGeometry() function is implemented to change the geometry
+    of the frame buffer whenever the geometry of the associated
+    top-level window changes. The image() function is called by the
+    window system when building window compositions to return an image
+    of the top-level window.
+
+    The paintDevice() function is implemented to return the appropriate
+    paint device.
+
+    \section1 Virtual Functions
+
+    When painting onto the surface, the window system will always call
+    the beginPaint() function before any painting operations are
+    performed. It ensures that the correct frame buffer will be used
+    by the OpenGL library for painting operations. Likewise, the
+    endPaint() function is automatically called when the painting is
+    done, but it isn't implemented for this example.
