DESCRIPTION
       The QStyle class specifies the look and feel of a GUI.

       A large number of GUI elements are common to many widgets. The QStyle class allows the
       look of these elements to be modified across all widgets that use the QStyle 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, QStyle provides a considerable amount of control and customisability.

       In Qt 1.x the look and feel option for widgets was specified by a single value: the
       GUIStyle. Starting with Qt 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 layout 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 layout. You can
       start your application with -reverse to check the mirrored layout. Also notice, that for a
       reversed layout, the light usually comes from top right instead of top left.

       The actual reverse layout is performed automatically when possible. However, for the sake
       of flexibility, the translation cannot be performed everywhere. The documentation for each
       function in the QStyle 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 visualRect() when necessary to
       translate logical coordinates into screen coordinates for drawing.

       In Qt 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(),
       drawControl(), drawControlMask(), drawComplexControl() and drawComplexControlMask(). 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 Style overview.

       Styles can also be created as plugins.

       See also Widget Appearance and Style.

MEMBER FUNCTION DOCUMENTATION
QStyle::QStyle ()
       Constructs a QStyle.

QStyle::~QStyle () [virtual]
       Destroys the style and frees all allocated resources.

int QStyle::defaultFrameWidth () const
       This function is obsolete. It is provided to keep old source working. We strongly advise
       against using it in new code.

void QStyle::drawComplexControl ( ComplexControl control, QPainter * p, const QWidget * widget,
       const QRect & r, const QColorGroup & cg, SFlags how = Style_Default, SCFlags sub = SC_All,
       SCFlags subActive = SC_None, const QStyleOption & opt = QStyleOption::Default ) const
       [pure virtual]
       Draws the ComplexControl control using the painter p in the area r. Colors are used from
       the color group cg. The sub argument specifies which SubControls to draw. Multiple
       SubControls can be OR'ed together. The subActive argument specifies which SubControl is
       active.

       The rect r should be in logical coordinates. Reimplementations of this function should use
       visualRect() to change the logical coordinates into screen coordinates when using
       drawPrimitive() and drawControl().

       The how argument is used to control how the ComplexControl is drawn. Multiple flags can
       OR'ed together. See the table below for an explanation of which flags are used with the
       various ComplexControls.

       The widget argument is a pointer to a QWidget or one of its subclasses. The widget can be
       cast to the appropriate type based on the value of control. The opt argument can be used
       to pass extra information required when drawing the ComplexControl. Note that opt may be
       the default value even for ComplexControls that can make use of the extra options. See the
       table below for the appropriate widget and opt usage:

       <center>.nf

       </center>

       See also ComplexControl and SubControl.

void QStyle::drawComplexControlMask ( ComplexControl control, QPainter * p, const QWidget *
       widget, const QRect & r, const QStyleOption & opt = QStyleOption::Default ) const [pure
       virtual]
       Draw a bitmask for the ComplexControl control using the painter p in the area r. See
       drawComplexControl() for an explanation of the use of the widget and opt arguments.

       The rect r should be in logical coordinates. Reimplementations of this function should use
       visualRect() to change the logical corrdinates into screen coordinates when using
       drawPrimitive() and drawControl().

       See also drawComplexControl() and ComplexControl.

void QStyle::drawControl ( ControlElement element, QPainter * p, const QWidget * widget, const
       QRect & r, const QColorGroup & cg, SFlags how = Style_Default, const QStyleOption & opt =
       QStyleOption::Default ) const [pure virtual]
       Draws the ControlElement element using the painter p in the area r. Colors are used from
       the color group cg.

       The rect r should be in screen coordinates.

       The how argument is used to control how the ControlElement is drawn. Multiple flags can be
       OR'ed together. See the table below for an explanation of which flags are used with the
       various ControlElements.

       The widget argument is a pointer to a QWidget or one of its subclasses. The widget can be
       cast to the appropriate type based on the value of element. The opt argument can be used
       to pass extra information required when drawing the ControlElement. Note that opt may be
       the default value even for ControlElements that can make use of the extra options. See the
       table below for the appropriate widget and opt usage:

       <center>.nf

       </center>

       See also ControlElement and StyleFlags.

void QStyle::drawControlMask ( ControlElement element, QPainter * p, const QWidget * widget,
       const QRect & r, const QStyleOption & opt = QStyleOption::Default ) const [pure virtual]
       Draw a bitmask for the ControlElement element using the painter p in the area r. See
       drawControl() for an explanation of the use of the widget and opt arguments.

       The rect r should be in screen coordinates.

       See also drawControl() and ControlElement.

void QStyle::drawItem ( QPainter * p, const QRect & r, int flags, const QColorGroup & g, bool
       enabled, const QPixmap * pixmap, const QString & text, int len = -1, const QColor *
       penColor = 0 ) const [virtual]
       Draws the text or pixmap in rectangle r using painter p and color group g. The pen color
       is specified with penColor. The enabled bool indicates whether or not the item is enabled;
       when reimplementing this bool should influence how the item is drawn. If len is -1 (the
       default) all the text is drawn; otherwise only the first len characters of text are drawn.
       The text is aligned and wrapped according to the alignment flags (see Qt::AlignmentFlags).

       By default, if both the text and the pixmap are not null, the pixmap is drawn and the text
       is ignored.

void QStyle::drawPrimitive ( PrimitiveElement pe, QPainter * p, const QRect & r, const
       QColorGroup & cg, SFlags flags = Style_Default, const QStyleOption & opt =
       QStyleOption::Default ) const [pure virtual]
       Draws the style PrimitiveElement pe using the painter p in the area r. Colors are used
       from the color group cg.

       The rect r should be in screen coordinates.

       The flags argument is used to control how the PrimitiveElement is drawn. Multiple flags
       can be OR'ed together.

       For example, a pressed button would be drawn with the flags Style_Enabled and Style_Down.

       The opt argument can be used to control how various PrimitiveElements are drawn. Note that
       opt may be the default value even for PrimitiveElements that make use of extra options.
       When opt is non-default, it is used as follows:

       <center>.nf

       </center>

       For all other PrimitiveElements, opt is unused.

       See also StyleFlags.

       Example: themes/wood.cpp.

QRect QStyle::itemRect ( QPainter * p, const QRect & r, int flags, bool enabled, const QPixmap *
       pixmap, const QString & text, int len = -1 ) const [virtual]
       Returns the appropriate area (see below) within rectangle r in which to draw the text or
       pixmap using painter p. If len is -1 (the default) all the text is drawn; otherwise only
       the first len characters of text are drawn. The text is aligned in accordance with the
       alignment flags (see Qt::AlignmentFlags). The enabled bool indicates whether or not the
       item is enabled.

       If r is larger than the area needed to render the text the rectangle that is returned will
       be offset within r in accordance with the alignment flags. For example if flags is
       AlignCenter the returned rectangle will be centered within r. If r is smaller than the
       area needed the rectangle that is returned will be larger than r (the smallest rectangle
       large enough to render the text or pixmap).

       By default, if both the text and the pixmap are not null, the pixmap is drawn and the text
       is ignored.

int QStyle::pixelMetric ( PixelMetric metric, const QWidget * widget = 0 ) const [pure virtual]
       Returns the pixel metric for metric. The widget argument is a pointer to a QWidget or one
       of its subclasses. The widget can be cast to the appropriate type based on the value of
       metric. Note that widget may be zero even for PixelMetrics that can make use of widget.
       See the table below for the appropriate widget casts:

       <center>.nf

       </center>

void QStyle::polish ( QWidget * ) [virtual]
       Initializes the appearance of a widget.

       This function is called for every widget at some point after it has been fully created but
       just before it is shown the very first time.

       Reasonable actions in this function might be to call QWidget::setBackgroundMode() for the
       widget. An example of highly unreasonable use would be setting the geometry!
       Reimplementing this function gives you a back-door through which you can change the
       appearance of a widget. With Qt 3.0's style engine you will rarely need to write your own
       polish(); instead reimplement drawItem(), drawPrimitive(), etc.

       The QWidget::inherits() function may provide enough information to allow class-specific
       customizations. But be careful not to hard-code things too much because new QStyle
       subclasses are expected to work reasonably with all current and future widgets.

       See also unPolish().

void QStyle::polish ( QApplication * ) [virtual]
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       Late initialization of the QApplication object.

       See also unPolish().

void QStyle::polish ( QPalette & ) [virtual]
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       The style may have certain requirements for color palettes. In this function it has the
       chance to change the palette according to these requirements.

       See also QPalette and QApplication::setPalette().

void QStyle::polishPopupMenu ( QPopupMenu * ) [pure virtual]
       Polishes the popup menu according to the GUI style. This usually means setting the mouse
       tracking (QPopupMenu::setMouseTracking()) and whether the menu is checkable by default
       (QPopupMenu::setCheckable()).

SubControl QStyle::querySubControl ( ComplexControl control, const QWidget * widget, const QPoint
       & pos, const QStyleOption & opt = QStyleOption::Default ) const [pure virtual]
       Returns the SubControl for widget at the point pos. The widget argument is a pointer to a
       QWidget or one of its subclasses. The widget can be cast to the appropriate type based on
       the value of control. The opt argument can be used to pass extra information required when
       drawing the ComplexControl. Note that opt may be the default value even for
       ComplexControls that can make use of the extra options. See drawComplexControl() for an
       explanation of the widget and opt arguments.

       Note that pos is passed in screen coordinates. When using querySubControlMetrics() to
       check for hits and misses, use visualRect() to change the logical coordinates into screen
       coordinates.

       See also drawComplexControl(), ComplexControl, SubControl, and querySubControlMetrics().

QRect QStyle::querySubControlMetrics ( ComplexControl control, const QWidget * widget, SubControl
       subcontrol, const QStyleOption & opt = QStyleOption::Default ) const [pure virtual]
       Returns the rect for the SubControl subcontrol for widget in logical coordinates.

       The widget argument is a pointer to a QWidget or one of its subclasses. The widget can be
       cast to the appropriate type based on the value of control. The opt argument can be used
       to pass extra information required when drawing the ComplexControl. Note that opt may be
       the default value even for ComplexControls that can make use of the extra options. See
       drawComplexControl() for an explanation of the widget and opt arguments.

       See also drawComplexControl(), ComplexControl, and SubControl.

QSize QStyle::scrollBarExtent () const
       This function is obsolete. It is provided to keep old source working. We strongly advise
       against using it in new code.

QSize QStyle::sizeFromContents ( ContentsType contents, const QWidget * widget, const QSize &
       contentsSize, const QStyleOption & opt = QStyleOption::Default ) const [pure virtual]
       Returns the size of widget based on the contents size contentsSize.

       The widget argument is a pointer to a QWidget or one of its subclasses. The widget can be
       cast to the appropriate type based on the value of contents. The opt argument can be used
       to pass extra information required when calculating the size. Note that opt may be the
       default value even for ContentsTypes that can make use of the extra options. See the table
       below for the appropriate widget and opt usage:

       <center>.nf

       </center>

int QStyle::styleHint ( StyleHint stylehint, const QWidget * widget = 0, const QStyleOption & opt
       = QStyleOption::Default, QStyleHintReturn * returnData = 0 ) const [pure virtual]
       Returns the style hint stylehint for widget. Currently, widget, opt, and returnData are
       unused; they're included to allow for future enhancements.

       For an explanation of the return value see StyleHint.

QPixmap QStyle::stylePixmap ( StylePixmap stylepixmap, const QWidget * widget = 0, const
       QStyleOption & opt = QStyleOption::Default ) const [pure virtual]
       Returns a pixmap for stylepixmap.

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

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

       <center>.nf

       </center>

       See also StylePixmap.

QRect QStyle::subRect ( SubRect subrect, const QWidget * widget ) const [pure virtual]
       Returns the sub-area subrect for the widget in logical coordinates.

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

       <center>.nf

       </center>

       The tear-off handle (SR_DockWindowHandleRect) for QDockWindow is a private class. Use
       QWidget::parentWidget() to access the QDockWindow:

	       if ( !widget->parentWidget() )
		   return;
	       const QDockWindow *dw = (const QDockWindow *) widget->parentWidget();

       See also SubRect.

void QStyle::tabbarMetrics ( const QWidget * t, int & hf, int & vf, int & ov ) const
       This function is obsolete. It is provided to keep old source working. We strongly advise
       against using it in new code.

void QStyle::unPolish ( QWidget * ) [virtual]
       Undoes the initialization of a widget's appearance.

       This function is the counterpart to polish. It is called for every polished widget when
       the style is dynamically changed. The former style has to unpolish its settings before the
       new style can polish them again.

       See also polish().

void QStyle::unPolish ( QApplication * ) [virtual]
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       Undoes the application polish.

       See also polish().

QRect QStyle::visualRect ( const QRect & logical, const QWidget * w ) [static]
       Returns the rect logical in screen coordinates. The bounding rect for widget w is used to
       perform the translation. This function is provided to aid style implementors in supporting
       right-to-left mode.

       See also QApplication::reverseLayout().

QRect QStyle::visualRect ( const QRect & logical, const QRect & bounding ) [static]
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       Returns the rect logical in screen coordinates. The rect bounding is used to perform the
       translation. This function is provided to aid style implementors in supporting right-to-
       left mode.

       See also QApplication::reverseLayout().
