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().
