-/*! \example widgets/orientation
-    \title Orientation Example
-
-    \brief The example shows a simple way to use different UIs depending on the screen
-    orientation of a mobile device.
-
-    \image orientation-landscape.png The UI in landscape mode
-    \image orientation-portrait.png The UI in portrait mode
-
-    The screen on many mobile devices can be viewed in both portrait and
-    landscape orientation. The orientation can be swiched with the help of a
-    hardware or software trigger. Due to the often small physical screen size,
-    user interfaces has to be very simple and compact to stay usable, and
-    applications usually occupy the whole screen. Designing a user interface
-    that works equally well in both landscape and portrait mode is not always
-    possible, however, so making a different layout for each case usually pays
-    off.
-
-    The example application makes use of two different UI widgets created with
-    the Qt Designer, one for portrait and one for landscape orientation. The
-    application has a widget that contains an image and the user is able to
-    select one of three images for it to show. In addition to the two UIs, the
-    application consists of a \c MainWindow class.
-
-    \section1 Landscape UI
-
-    If the screen is in landscape mode, the user probably holds the device with
-    both hands and is ready to give full attention to the application. The
-    landscape UI looks like this:
-
-    \image orientation-landscape-ui.png The landscape UI
-
-    To the left is a QWidget called \c choiceWidget, which will show the
-    current image, and to the right are three QRadioButton instances. The
-    active radio button specifies the image to show.
-
-    \section1 Portrait UI
-
-    When the device is in portrait mode, it usually means that the user holds
-    it with one hand, and can comfortably use the thumb for small amounts of
-    input. The layout is simpler, and is focused on consuming content. The
-    portrait UI looks like this:
-
-    \image orientation-portrait-ui.png The portrait UI
-
-    Similarly, it contains a QWidget, also called \c choiceWidget, that will
-    show the current image. In contrast to the landscape UI, this one doesn't
-    provide any controls to change the image.
-
-    \section1 MainWindow Class Definition
-
-    \c MainWindow inherits from QWidget and acts as the top level widget of the
-    application.
-
-    \snippet widgets/orientation/mainwindow.h 0
-
-    The \c resizeEvent() method is re-implemented, and used to check which
-    UI to show. The \c onRadioButtonClicked() slot is connected to the
-    landscape UI's radio button group and selects the current image.
-
-    \c landscapeWidget and \c portraitWidget will contain the UI layouts. Only
-    one of them is visible at a time.
-
-    \section1 MainWindow Class Implementation
-
-    In the constructor, the widgets that will hold the UIs are created and set
-    up.
-
-    \snippet widgets/orientation/mainwindow.cpp 0
-
-    Since the exit buttons on the layouts are different from each other, both
-    of them have to have their \c clicked() signal connected to the \c close()
-    slot of the main widget. The first image is also made current with the call
-    to \c onRadioButtonClicked().
-
-    \snippet widgets/orientation/mainwindow.cpp 1
-
-    On the Maemo platform, windows are stuck in landscape mode by default. The
-    application has to explicitly say that rotation is supported.
-
-    \snippet widgets/orientation/mainwindow.cpp 2
-
-    The \c resizeEvent() is called when the main window is first created, and
-    also whenever the window has been resized. If the window is shown in
-    full screen, this is an indication that the orientation of the screen has
-    changed.
-
-    The dimensions of \c landscapeWidget is the transpose of the dimensions of
-    \c portraitWidget. When the orientation is known, both are set to the
-    (possibly transposed) size of the window. Depending on the orientation, one
-    widget is made visible and the other invisible.
-
-    \snippet widgets/orientation/mainwindow.cpp 3
-
-    When the user selects one of the radio buttons in the landscape UI, the
-    current image is changed. The image is displayed by specifying the
-    background style of the choice widget. Since both \c portrait and
-    \c landscape have a \c choiceWidget of their own, the change has to be
-    reflected in both instances.
-
-    \snippet widgets/orientation/mainwindow.cpp 4
-
-    Synchronizing both UIs like this might become unfeasible when there are
-    many things that can change. In that case it is better to make use of the
-    \l{Introduction to Model/View Programming}{Model-View-Controller pattern}
-    more extensively and share the content between both portrait and landscape
-    widgets. Then an interface for displaying and manipulating it can be tailor
-    made for both orientations.
-
-    \section1 The \c main() Function
-
-    The main function creates a \c MainWindow instance and shows it full
-    screen.

-    \title Application Icon Example
-
-    \brief The example shows how to add an application icon to a mobile application.
-
-    \image appicon_screenshot.png The icon on a Nokia XPressMusic 5800
-
-    \section1 Adding the icons to the project
-
-    For Maemo, we need to add that the \c .desktop and icon file should be
-    installed.
-
-    \quotefile widgets/applicationicon/applicationicon.pro
-
-    Currently, Qt Creator doesn't include the icon and desktop files in the
-    application package for Maemo, merely the executable file is included. As a
-    workaround for this, the files can be added manually in the Projects tab.
-    In the "Create Package" build step for the Maemo target, the \c .desktop
-    file and icon can be added to be a part of the package contents.
-    Unfortunately, these additions are only stored as a part of the
-    \c .pro.user file. This issue will be resolved in a future release of
-    Qt Creator.
