    \title QtScript Tetrix Example

    The Tetrix example is a QtScript version of the classic Tetrix game.

    \image tetrix-example.png

    The program logic in this example is a fairly straight port of the
    logic in the C++ \l{Tetrix Example}.
    The graphical user interface is defined in a UI file.

    \snippet examples/script/tetrix/main.cpp 0

    We define a custom UI loader that handles our TetrixBoard widget; the
    TetrixBoard is the main component of the UI (where the pieces are
    drawn).

    \snippet examples/script/tetrix/main.cpp 1

    We initialize the script engine to have the Qt namespace, so that e.g.
    Qt.Key_Left will be available to script code. We also make the
    application object available (for the quit() slot).

    \snippet examples/script/tetrix/main.cpp 2

    Several scripts are evaluated as part of the engine setup process.
    tetrixpiece.js contains the definition of the TetrixPiece class, which
    is used to populate the play field. tetrixboard.js contains the
    definition of the TetrixBoard class, which contains the main game logic.
    Finally, tetrixwindow.js contains the definition of the TetrixWindow
    class, which wires up the top-level widget.

    \snippet examples/script/tetrix/main.cpp 3

    A form is created from the UI file. A new TetrixWindow script object
    is then constructed, passing the form as argument.

    \snippet examples/script/tetrix/main.cpp 4

    The form is shown, and the event loop is entered.
