+ \class QStyle
+ \brief The QStyle class is an abstract base class that encapsulates the look and feel of a GUI.
+
+ \ingroup appearance
+
+ Qt contains a set of QStyle subclasses that emulate the styles of
+ the different platforms supported by Qt (QWindowsStyle,
+ QMacStyle, QMotifStyle, etc.). By default, these styles are built
+ into the QtGui library. Styles can also be made available as
+ plugins.
+
+ Qt's built-in widgets use QStyle to perform nearly all of their
+ drawing, ensuring that they look exactly like the equivalent
+ native widgets. The diagram below shows a QComboBox in eight
+ different styles.
+
+ \img qstyle-comboboxes.png Eight combo boxes
+
+ Topics:
+
+ \tableofcontents
+
+ \section1 Setting a Style
+
+ The style of the entire application can be set using the
+ QApplication::setStyle() function. It can also be specified by the
+ user of the application, using the \c -style command-line option:
+
+ \snippet doc/src/snippets/code/src_gui_styles_qstyle.cpp 0
+
+ If no style is specified, Qt will choose the most appropriate
+ style for the user's platform or desktop environment.
+
+ A style can also be set on an individual widget using the
+ QWidget::setStyle() function.
+
+ \section1 Developing Style-Aware Custom Widgets
+
+ If you are developing custom widgets and want them to look good on
+ all platforms, you can use QStyle functions to perform parts of
+ the widget drawing, such as drawItemText(), drawItemPixmap(),
+ drawPrimitive(), drawControl(), and drawComplexControl().
+
+ Most QStyle draw functions take four arguments:
+ \list
+ \o an enum value specifying which graphical element to draw
+ \o a QStyleOption specifying how and where to render that element
+ \o a QPainter that should be used to draw the element
+ \o a QWidget on which the drawing is performed (optional)
+ \endlist
+
+ For example, if you want to draw a focus rectangle on your
+ widget, you can write:
+
+ \snippet doc/src/snippets/styles/styles.cpp 1
+
+ QStyle gets all the information it needs to render the graphical
+ element from QStyleOption. The widget is passed as the last
+ argument in case the style needs it to perform special effects
+ (such as animated default buttons on Mac OS X), but it isn't
+ mandatory. In fact, you can use QStyle to draw on any paint
+ device, not just widgets, by setting the QPainter properly.
+
+ QStyleOption has various subclasses for the various types of
+ graphical elements that can be drawn. For example,
+ PE_FrameFocusRect expects a QStyleOptionFocusRect argument.
+
+ To ensure that drawing operations are as fast as possible,
+ QStyleOption and its subclasses have public data members. See the
+ QStyleOption class documentation for details on how to use it.
+
+ For convenience, Qt provides the QStylePainter class, which
+ combines a QStyle, a QPainter, and a QWidget. This makes it
+ possible to write
+
+ \snippet doc/src/snippets/styles/styles.cpp 5
+ \dots
+ \snippet doc/src/snippets/styles/styles.cpp 7
+
+ instead of
+
+ \snippet doc/src/snippets/styles/styles.cpp 2
+ \dots
+ \snippet doc/src/snippets/styles/styles.cpp 3
+
+ \section1 Creating a Custom Style
+
+ You can create a custom look and feel for your application by
+ creating a custom style. There are two approaches to creating a
+ custom style. In the static approach, you either choose an
+ existing QStyle class, subclass it, and reimplement virtual
+ functions to provide the custom behavior, or you create an entire
+ QStyle class from scratch. In the dynamic approach, you modify the
+ behavior of your system style at runtime. The static approach is
+ described below. The dynamic approach is described in QProxyStyle.
+
+ The first step in the static approach is to pick one of the styles
+ provided by Qt from which you will build your custom style. Your
+ choice of QStyle class will depend on which style resembles your
+ desired style the most. The most general class that you can use as
+ a base is QCommonStyle (not QStyle). This is because Qt requires
+ its styles to be \l{QCommonStyle}s.
+
+ Depending on which parts of the base style you want to change,
+ you must reimplement the functions that are used to draw those
+ parts of the interface. To illustrate this, we will modify the
+ look of the spin box arrows drawn by QWindowsStyle. The arrows
+ are \e{primitive elements} that are drawn by the drawPrimitive()
+ function, so we need to reimplement that function. We need the
+ following class declaration:
+
+ \snippet doc/src/snippets/customstyle/customstyle.h 0
+
+ To draw its up and down arrows, QSpinBox uses the
+ PE_IndicatorSpinUp and PE_IndicatorSpinDown primitive elements.
+ Here's how to reimplement the drawPrimitive() function to draw
+ them differently:
+
+ \snippet doc/src/snippets/customstyle/customstyle.cpp 2
+ \snippet doc/src/snippets/customstyle/customstyle.cpp 3
+ \snippet doc/src/snippets/customstyle/customstyle.cpp 4
+
+ Notice that we don't use the \c widget argument, except to pass it
+ on to the QWindowStyle::drawPrimitive() function. As mentioned
+ earlier, the information about what is to be drawn and how it
+ should be drawn is specified by a QStyleOption object, so there is
+ no need to ask the widget.
+
+ If you need to use the \c widget argument to obtain additional
+ information, be careful to ensure that it isn't 0 and that it is
+ of the correct type before using it. For example:
+
+ \snippet doc/src/snippets/customstyle/customstyle.cpp 0
+ \dots
+ \snippet doc/src/snippets/customstyle/customstyle.cpp 1
+
+ When implementing a custom style, you cannot assume that the
+ widget is a QSpinBox just because the enum value is called
+ PE_IndicatorSpinUp or PE_IndicatorSpinDown.
+
+ The documentation for the \l{widgets/styles}{Styles} example
+ covers this topic in more detail.
+
+ \warning Qt style sheets are currently not supported for custom QStyle
+ subclasses. We plan to address this in some future release.
+
+
+ \section1 Using a Custom Style
+
+ There are several ways of using a custom style in a Qt
+ application. The simplest way is to pass the custom style to the
+ QApplication::setStyle() static function before creating the
+ QApplication object:
+
+ \snippet snippets/customstyle/main.cpp using a custom style
+
+ You can call QApplication::setStyle() at any time, but by calling
+ it before the constructor, you ensure that the user's preference,
+ set using the \c -style command-line option, is respected.
+
+ You may want to make your custom style available for use in other
+ applications, which may not be yours and hence not available for
+ you to recompile. The Qt Plugin system makes it possible to create
+ styles as plugins. Styles created as plugins are loaded as shared
+ objects at runtime by Qt itself. Please refer to the \link
+ plugins-howto.html Qt Plugin\endlink documentation for more
+ information on how to go about creating a style plugin.
+
+ Compile your plugin and put it into Qt's \c plugins/styles
+ directory. We now have a pluggable style that Qt can load
+ automatically. To use your new style with existing applications,
+ simply start the application with the following argument:
+
+ \snippet doc/src/snippets/code/src_gui_styles_qstyle.cpp 1
+
+ The application will use the look and feel from the custom style you
+ implemented.
+
+ \section1 Right-to-Left Desktops
+
+ Languages written from right to left (such as Arabic and Hebrew)
+ usually also mirror the whole layout of widgets, and require the
+ light to come from the screen's top-right corner instead of
+ top-left.
+
+ If you create a custom style, you should take special care when
+ drawing asymmetric elements to make sure that they also look
+ correct in a mirrored layout. An easy way to test your styles is
+ to run applications with the \c -reverse command-line option or
+ to call QApplication::setLayoutDirection() in your \c main()
+ function.
+
+ Here are some things to keep in mind when making a style work well in a
+ right-to-left environment:
+
+ \list
+ \o subControlRect() and subElementRect() return rectangles in screen coordinates
+ \o QStyleOption::direction indicates in which direction the item should be drawn in
+ \o If a style is not right-to-left aware it will display items as if it were left-to-right
+ \o visualRect(), visualPos(), and visualAlignment() are helpful functions that will
+ translate from logical to screen representations.
+ \o alignedRect() will return a logical rect aligned for the current direction
+ \endlist
+
+ \section1 Styles in Item Views
+
+ The painting of items in views is performed by a delegate. Qt's
+ default delegate, QStyledItemDelegate, is also used for for calculating bounding
+ rectangles of items, and their sub-elements for the various kind
+ of item \l{Qt::ItemDataRole}{data roles}
+ QStyledItemDelegate supports. See the QStyledItemDelegate class
+ description to find out which datatypes and roles are supported. You
+ can read more about item data roles in \l{Model/View Programming}.
+
+ When QStyledItemDelegate paints its items, it draws
+ CE_ItemViewItem, and calculates their size with CT_ItemViewItem.
+ Note also that it uses SE_ItemViewItemText to set the size of
+ editors. When implementing a style to customize drawing of item
+ views, you need to check the implementation of QCommonStyle (and
+ any other subclasses from which your style
+ inherits). This way, you find out which and how
+ other style elements are painted, and you can then reimplement the
+ painting of elements that should be drawn differently.
+
+ We include a small example where we customize the drawing of item
+ backgrounds.
+
+ \snippet doc/src/snippets/customviewstyle.cpp 0
+
+ The primitive element PE_PanelItemViewItem is responsible for
+ painting the background of items, and is called from
+ \l{QCommonStyle}'s implementation of CE_ItemViewItem.
+
+ To add support for drawing of new datatypes and item data roles,
+ it is necessary to create a custom delegate. But if you only
+ need to support the datatypes implemented by the default
+ delegate, a custom style does not need an accompanying
+ delegate. The QStyledItemDelegate class description gives more
+ information on custom delegates.
+
+ The drawing of item view headers is also done by the style, giving
+ control over size of header items and row and column sizes.
