\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. | |

actions in this function might be to call the | |

the function to set, for example, the geometry. Reimplementing | |
this function provides a back-door through which the appearance | |
of a widget can be changed, but with Qt's style engine it is | |
rarely necessary to implement this function; reimplement | |
drawItemPixmap(), drawItemText(), drawPrimitive(), etc. instead. | |
The QWidget::inherits() function may provide enough information to | |
allow class-specific customizations. But because new QStyle | |
subclasses are expected to work reasonably with all current and \e | |
future widgets, limited use of hard-coded customization is | |
recommended. | |
