47
48	Qt's built-in widgets use the QStyle class to perform nearly all
49	of their drawing. QStyle is an abstract base class that
50	encapsulates the look and feel of a GUI, and can be used to make
51	the widgets look exactly like the equivalent native widgets or to
52	give the widgets a custom look.
53
54	Qt provides a set of QStyle subclasses that emulate the native
55	look of the different platforms supported by Qt (QWindowsStyle,
56	QMacStyle, etc.). These styles are built into the
57	Qt GUI module, other styles can be made available using Qt's
58	plugin mechanism.
59
60	Most functions for drawing style elements take four arguments:
61
62	\list
63	\li an enum value specifying which graphical element to draw
64	\li a QStyleOption object specifying how and where to render that element
65	\li a QPainter object that should be used to draw the element
66	\li a QWidget object on which the drawing is performed (optional)
67	\endlist
68
69	The style gets all the information it needs to render the
70	graphical element from the QStyleOption class. The widget is
71	passed as the last argument in case the style needs it to perform
72	special effects (such as animated default buttons on \macos),
73	but it isn't mandatory. In fact, QStyle can be used to draw on any
74	paint device (not just widgets), in which case the widget argument
75	is a zero pointer.
76
77	\image paintsystem-stylepainter.png
78
79	The paint system also provides the QStylePainter class inheriting
80	from QPainter. QStylePainter is a convenience class for drawing
81	QStyle elements inside a widget, and extends QPainter with a set
82	of high-level drawing functions implemented on top of QStyle's
83	API. The advantage of using QStylePainter is that the parameter
84	lists get considerably shorter.
85
86	\table 100%
87	\row
88	\li \inlineimage paintsystem-icon.png
89	\li \b QIcon
90
91	The QIcon class provides scalable icons in different modes and states.
92
93	QIcon can generate pixmaps reflecting an icon's state, mode and
94	size. These pixmaps are generated from the set of pixmaps
95	made available to the icon, and are used by Qt widgets to show an
96	icon representing a particular action.
97
98	The rendering of a QIcon object is handled by the QIconEngine
99	class. Each icon has a corresponding icon engine that is
100	responsible for drawing the icon with a requested size, mode and
101	state.

112	\brief The QStyle class is an abstract base class that encapsulates the look and feel of a GUI.
113
114	\ingroup appearance
115	\inmodule QtWidgets
116
117	Qt contains a set of QStyle subclasses that emulate the styles of
118	the different platforms supported by Qt (QWindowsStyle,
119	QMacStyle etc.). By default, these styles are built
120	into the Qt GUI module. Styles can also be made available as
121	plugins.
122
123	Qt's built-in widgets use QStyle to perform nearly all of their
124	drawing, ensuring that they look exactly like the equivalent
125	native widgets. The diagram below shows a QComboBox in nine
126	different styles.
127
128	\image qstyle-comboboxes.png Nine combo boxes
129
130	Topics:
131
132	\section1 Setting a Style
133
134	The style of the entire application can be set using the
135	QApplication::setStyle() function. It can also be specified by the
136	user of the application, using the \c -style command-line option:
137
138	\snippet code/src_gui_styles_qstyle.cpp 0
139
140	If no style is specified, Qt will choose the most appropriate
141	style for the user's platform or desktop environment.
142
143	A style can also be set on an individual widget using the
144	QWidget::setStyle() function.
145
146	\section1 Developing Style-Aware Custom Widgets
147
148	If you are developing custom widgets and want them to look good on
149	all platforms, you can use QStyle functions to perform parts of
150	the widget drawing, such as drawItemText(), drawItemPixmap(),
151	drawPrimitive(), drawControl(), and drawComplexControl().
152
153	Most QStyle draw functions take four arguments:
154	\list
155	\li an enum value specifying which graphical element to draw
156	\li a QStyleOption specifying how and where to render that element
157	\li a QPainter that should be used to draw the element
158	\li a QWidget on which the drawing is performed (optional)
159	\endlist
160
161	For example, if you want to draw a focus rectangle on your
162	widget, you can write:
163
164	\snippet styles/styles.cpp 1
165
166	QStyle gets all the information it needs to render the graphical
167	element from QStyleOption. The widget is passed as the last
168	argument in case the style needs it to perform special effects
169	(such as animated default buttons on \macos), but it isn't
170	mandatory. In fact, you can use QStyle to draw on any paint
171	device, not just widgets, by setting the QPainter properly.
172
173	QStyleOption has various subclasses for the various types of
174	graphical elements that can be drawn. For example,
175	PE_FrameFocusRect expects a QStyleOptionFocusRect argument.
176
177	To ensure that drawing operations are as fast as possible,
178	QStyleOption and its subclasses have public data members. See the
179	QStyleOption class documentation for details on how to use it.
180
181	For convenience, Qt provides the QStylePainter class, which
182	combines a QStyle, a QPainter, and a QWidget. This makes it
183	possible to write
184
185	\snippet styles/styles.cpp 5
186	\dots
187	\snippet styles/styles.cpp 7
188
189	instead of
190
191	\snippet styles/styles.cpp 2
192	\dots
193	\snippet styles/styles.cpp 3
194
195	\section1 Creating a Custom Style
196
197	You can create a custom look and feel for your application by
198	creating a custom style. There are two approaches to creating a
199	custom style. In the static approach, you either choose an
200	existing QStyle class, subclass it, and reimplement virtual
201	functions to provide the custom behavior, or you create an entire
202	QStyle class from scratch. In the dynamic approach, you modify the
203	behavior of your system style at runtime. The static approach is
204	described below. The dynamic approach is described in QProxyStyle.
205
206	The first step in the static approach is to pick one of the styles
207	provided by Qt from which you will build your custom style. Your
208	choice of QStyle class will depend on which style resembles your
209	desired style the most. The most general class that you can use as
210	a base is QCommonStyle (not QStyle). This is because Qt requires
211	its styles to be \l{QCommonStyle}s.
212
213	Depending on which parts of the base style you want to change,
214	you must reimplement the functions that are used to draw those
215	parts of the interface. To illustrate this, we will modify the
216	look of the spin box arrows drawn by QWindowsStyle. The arrows
217	are \e{primitive elements} that are drawn by the drawPrimitive()
218	function, so we need to reimplement that function. We need the
219	following class declaration:
220
221	\snippet customstyle/customstyle.h 0
222
223	To draw its up and down arrows, QSpinBox uses the
224	PE_IndicatorSpinUp and PE_IndicatorSpinDown primitive elements.
225	Here's how to reimplement the drawPrimitive() function to draw
226	them differently:
227
228	\snippet customstyle/customstyle.cpp 2
229	\snippet customstyle/customstyle.cpp 3
230	\snippet customstyle/customstyle.cpp 4
231
232	Notice that we don't use the \c widget argument, except to pass it
233	on to the QWindowStyle::drawPrimitive() function. As mentioned
234	earlier, the information about what is to be drawn and how it
235	should be drawn is specified by a QStyleOption object, so there is
236	no need to ask the widget.
237
238	If you need to use the \c widget argument to obtain additional
239	information, be careful to ensure that it isn't 0 and that it is
240	of the correct type before using it. For example:
241
242	\snippet customstyle/customstyle.cpp 0
243	\dots
244	\snippet customstyle/customstyle.cpp 1
245
246	When implementing a custom style, you cannot assume that the
247	widget is a QSpinBox just because the enum value is called
248	PE_IndicatorSpinUp or PE_IndicatorSpinDown.
249
250	\warning Qt style sheets are currently not supported for custom QStyle
251	subclasses. We plan to address this in some future release.
252
253
254	\section1 Using a Custom Style
255
256	There are several ways of using a custom style in a Qt
257	application. The simplest way is to pass the custom style to the
258	QApplication::setStyle() static function before creating the
259	QApplication object:
260
261	\snippet customstyle/main.cpp using a custom style
262
263	You can call QApplication::setStyle() at any time, but by calling
264	it before the constructor, you ensure that the user's preference,
265	set using the \c -style command-line option, is respected.
266
267	You may want to make your custom style available for use in other
268	applications, which may not be yours and hence not available for
269	you to recompile. The Qt Plugin system makes it possible to create
270	styles as plugins. Styles created as plugins are loaded as shared
271	objects at runtime by Qt itself. Please refer to the \l{How to Create Qt Plugins}{Qt Plugin}
272	documentation for more information on how to go about creating a style
273	plugin.
274
275	Compile your plugin and put it into Qt's \c plugins/styles
276	directory. We now have a pluggable style that Qt can load
277	automatically. To use your new style with existing applications,
278	simply start the application with the following argument:
279
280	\snippet code/src_gui_styles_qstyle.cpp 1
281
282	The application will use the look and feel from the custom style you
283	implemented.
284
285	\section1 Right-to-Left Desktops
286
287	Languages written from right to left (such as Arabic and Hebrew)
288	usually also mirror the whole layout of widgets, and require the
289	light to come from the screen's top-right corner instead of
290	top-left.
291
292	If you create a custom style, you should take special care when
293	drawing asymmetric elements to make sure that they also look
294	correct in a mirrored layout. An easy way to test your styles is
295	to run applications with the \c -reverse command-line option or
296	to call QApplication::setLayoutDirection() in your \c main()
297	function.
298
299	Here are some things to keep in mind when making a style work well in a
300	right-to-left environment:
301
302	\list
303	\li subControlRect() and subElementRect() return rectangles in screen coordinates
304	\li QStyleOption::direction indicates in which direction the item should be drawn in
305	\li If a style is not right-to-left aware it will display items as if it were left-to-right
306	\li visualRect(), visualPos(), and visualAlignment() are helpful functions that will
307	translate from logical to screen representations.
308	\li alignedRect() will return a logical rect aligned for the current direction
309	\endlist
310
311	\section1 Styles in Item Views
312
313	The painting of items in views is performed by a delegate. Qt's
314	default delegate, QStyledItemDelegate, is also used for calculating bounding
315	rectangles of items, and their sub-elements for the various kind
316	of item \l{Qt::ItemDataRole}{data roles}
317	QStyledItemDelegate supports. See the QStyledItemDelegate class
318	description to find out which datatypes and roles are supported. You
319	can read more about item data roles in \l{Model/View Programming}.
320
321	When QStyledItemDelegate paints its items, it draws
322	CE_ItemViewItem, and calculates their size with CT_ItemViewItem.
323	Note also that it uses SE_ItemViewItemText to set the size of
324	editors. When implementing a style to customize drawing of item
325	views, you need to check the implementation of QCommonStyle (and
326	any other subclasses from which your style
327	inherits). This way, you find out which and how
328	other style elements are painted, and you can then reimplement the
329	painting of elements that should be drawn differently.
330
331	We include a small example where we customize the drawing of item
332	backgrounds.
333
334	\snippet customviewstyle/customviewstyle.cpp 0
335
336	The primitive element PE_PanelItemViewItem is responsible for
337	painting the background of items, and is called from
338	\l{QCommonStyle}'s implementation of CE_ItemViewItem.
339
340	To add support for drawing of new datatypes and item data roles,
341	it is necessary to create a custom delegate. But if you only
342	need to support the datatypes implemented by the default
343	delegate, a custom style does not need an accompanying
344	delegate. The QStyledItemDelegate class description gives more
345	information on custom delegates.
346
347	The drawing of item view headers is also done by the style, giving
348	control over size of header items and row and column sizes.
