    \class TQStyleOption tqstyle.h
    \brief The TQStyleOption class specifies optional parameters for TQStyle functions.
    \ingroup appearance

    Some TQStyle functions take an optional argument specifying extra
    information that is required for a paritical primitive or control.
    So that the TQStyle class can be extended, TQStyleOption is used to
    provide a variable-argument for these options.

    The TQStyleOption class has constructors for each type of optional
    argument, and this set of constructors may be extended in future
    TQt releases. There are also corresponding access functions that
    return the optional arguments: these too may be extended.

    For each constructor, you should refer to the documentation of the
    TQStyle functions to see the meaning of the arguments.

    When calling TQStyle functions from your own widgets, you must only
    pass the default TQStyleOption or the argument that TQStyle is
    documented to accept. For example, if the function expects
    TQStyleOption(TQMenuItem *, int), passing TQStyleOption(TQMenuItem *)
    leaves the optional integer argument uninitialized.

    When subclassing TQStyle, you must similarly only expect the
    default or documented arguments. The other arguments will have
    uninitialized values.

    If you make your own TQStyle subclasses and your own widgets, you
    can make a subclass of TQStyleOption to pass additional arguments
    to your TQStyle subclass. You will need to cast the "const
    TQStyleOption&" argument to your subclass, so be sure your style
    has been called from your widget.

    \class TQStyle tqstyle.h
    \brief The TQStyle class specifies the look and feel of a GUI.
    \ingroup appearance

    A large number of GUI elements are common to many widgets. The
    TQStyle class allows the look of these elements to be modified
    across all widgets that use the TQStyle functions. It also
    provides two feel options: Motif and Windows.

    Although it is not possible to fully enumerate the look of
    graphical elements and the feel of widgets in a GUI, TQStyle
    provides a considerable amount of control and customisability.

    In TQt 1.x the look and feel option for widgets was specified by a
    single value: the GUIStyle. Starting with TQt 2.0, this notion was
    expanded to allow the look to be specified by virtual drawing
    functions.

    Derived classes may reimplement some or all of the drawing
    functions to modify the look of all widgets that use those
    functions.

    Languages written from right to left (such as Arabic and Hebrew)
    usually also mirror the whole tqlayout of widgets. If you design a
    style, you should take special care when drawing asymmetric
    elements to make sure that they also look correct in a mirrored
    tqlayout. You can start your application with \c -reverse to check
    the mirrored tqlayout. Also notice, that for a reversed tqlayout, the
    light usually comes from top right instead of top left.

    The actual reverse tqlayout is performed automatically when
    possible. However, for the sake of flexibility, the translation
    cannot be performed everywhere. The documentation for each
    function in the TQStyle API states whether the function
    expects/returns logical or screen coordinates. Using logical
    coordinates (in ComplexControls, for example) provides great
    flexibility in controlling the look of a widget. Use tqvisualRect()
    when necessary to translate logical coordinates into screen
    coordinates for drawing.

    In TQt versions prior to 3.0, if you wanted a low level route into
    changing the appearance of a widget, you would reimplement
    polish(). With the new 3.0 style engine the recommended approach
    is to reimplement the draw functions, for example drawItem(),
    drawPrimitive(), tqdrawControl(), tqdrawControlMask(),
    tqdrawComplexControl() and tqdrawComplexControlMask(). Each of these
    functions is called with a range of parameters that provide
    information that you can use to determine how to draw them, e.g.
    style flags, rectangle, color group, etc.

    For information on changing elements of an existing style or
    creating your own style see the \link customstyles.html Style
    overview\endlink.

    Styles can also be created as \link plugins-howto.html
    plugins\endlink.

    \value SP_TitleBarMaxButton  maximize button on titlebars.
    \value SP_TitleBarCloseButton  close button on titlebars.
    \value SP_TitleBarNormalButton  normal (restore) button on titlebars.

    \value SP_MessageBoxWarning the 'warning' icon.
    \value SP_MessageBoxCritical the 'critical' icon.
    \value SP_MessageBoxQuestion the 'question' icon.


    \value SP_DockWindowCloseButton  close button on dock windows;

    \fn TQPixmap TQStyle::stylePixmap( StylePixmap stylepixmap, const TQWidget *widget = 0, const TQStyleOption& opt = TQStyleOption::Default ) const;

    Returns a pixmap for \a stylepixmap.

    The \a opt argument can be used to pass extra information required
    when drawing the ControlElement. Note that \a opt may be the
    default value even for StylePixmaps that can make use of the extra
    options. Currently, the \a opt argument is unused.

    The \a widget argument is a pointer to a TQWidget or one of its
    subclasses. The widget can be cast to the appropriate type based
    on the value of \a stylepixmap. See the table below for the
    appropriate \a widget casts:
