    \class QSizePolicy

    \brief The QSizePolicy class is a layout attribute describing horizontal

    and vertical resizing policy.

    \ingroup geomanagement

    The size policy of a widget is an expression of its willingness to

    be resized in various ways, and affects how the widget is treated

    by the \l{Layout Management}{layout engine}. Each widget returns a

    QSizePolicy that describes the horizontal and vertical resizing

    policy it prefers when being laid out. You can change this for

    a specific widget by changing its QWidget::sizePolicy property.

    QSizePolicy contains two independent QSizePolicy::Policy values

    and two stretch factors; one describes the widgets's horizontal

    size policy, and the other describes its vertical size policy. It

    also contains a flag to indicate whether the height and width of

    its preferred size are related.

    The horizontal and vertical policies can be set in the

    constructor, and altered using the setHorizontalPolicy() and

    setVerticalPolicy() functions. The stretch factors can be set

    using the setHorizontalStretch() and setVerticalStretch()

    functions. The flag indicating whether the widget's

    \l{QWidget::sizeHint()}{sizeHint()} is width-dependent (such as a

    menu bar or a word-wrapping label) can be set using the

    setHeightForWidth() function.

    The current size policies and stretch factors be retrieved using

    the horizontalPolicy(), verticalPolicy(), horizontalStretch() and

    verticalStretch() functions. Alternatively, use the transpose()

    function to swap the horizontal and vertical policies and

    stretches. The hasHeightForWidth() function returns the current

    status of the flag indicating the size hint dependencies.

    Use the expandingDirections() function to determine whether the

    associated widget can make use of more space than its

    \l{QWidget::sizeHint()}{sizeHint()} function indicates, as well as

    find out in which directions it can expand.

    Finally, the QSizePolicy class provides operators comparing this

    size policy to a given policy, as well as a QVariant operator

    storing this QSizePolicy as a QVariant object.

/*!

    \enum QSizePolicy::PolicyFlag

    These flags are combined together to form the various \l{Policy}

    values:

    \value GrowFlag  The widget can grow beyond its size hint if necessary.

    \value ExpandFlag  The widget should get as much space as possible.

    \value ShrinkFlag  The widget can shrink below its size hint if necessary.

    \value IgnoreFlag  The widget's size hint is ignored. The widget will get

        as much space as possible.

    \sa Policy

*/

/*!

    \enum QSizePolicy::Policy

    This enum describes the various per-dimension sizing types used

    when constructing a QSizePolicy.

    \value Fixed  The QWidget::sizeHint() is the only acceptable

        alternative, so the widget can never grow or shrink (e.g. the

        vertical direction of a push button).

    \value Minimum  The sizeHint() is minimal, and sufficient. The

        widget can be expanded, but there is no advantage to it being

        larger (e.g. the horizontal direction of a push button).

        It cannot be smaller than the size provided by sizeHint().

    \value Maximum  The sizeHint() is a maximum. The widget can be

        shrunk any amount without detriment if other widgets need the

        space (e.g. a separator line).

        It cannot be larger than the size provided by sizeHint().

    \value Preferred  The sizeHint() is best, but the widget can be

        shrunk and still be useful. The widget can be expanded, but there

        is no advantage to it being larger than sizeHint() (the default

        QWidget policy).

    \value Expanding  The sizeHint() is a sensible size, but the

        widget can be shrunk and still be useful. The widget can make use

        of extra space, so it should get as much space as possible (e.g.

        the horizontal direction of a horizontal slider).

    \value MinimumExpanding  The sizeHint() is minimal, and sufficient.

        The widget can make use of extra space, so it should get as much

        space as possible (e.g. the horizontal direction of a horizontal

        slider).

    \value Ignored  The sizeHint() is ignored. The widget will get as

        much space as possible.

    \fn QSizePolicy::QSizePolicy()

    Constructs a QSizePolicy object with \l Fixed as its horizontal

    and vertical policies.

    The policies can be altered using the setHorizontalPolicy() and

    function if the preferred height of the widget is dependent on the

    width of the widget (for example, a QLabel with line wrapping).

    Returns whether a widget can make use of more space than the

    A value of Qt::Horizontal or Qt::Vertical means that the widget

    can grow horizontally or vertically (i.e., the horizontal or

    vertical policy is \l Expanding or \l MinimumExpanding), whereas

    Qt::Horizontal | Qt::Vertical means that it can grow in both

    Sets the control type associated with the widget for which this

    The control type specifies the type of the widget for which this

    size policy applies. It is used by some styles, notably

    QMacStyle, to insert proper spacing between widgets. For example,
