Detailed Description

The QStyle class is an abstract base class that encapsulates the look and feel of a GUI.

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.

Topics:

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 -style command-line option:

./myapplication -style motif

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.

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:

For example, if you want to draw a focus rectangle on your widget, you can write:

void MyWidget::paintEvent(QPaintEvent * /* event */)
{
QPainter painter(this);
QStyleOptionFocusRect option;
option.initFrom(this);
option.backgroundColor = palette().color(QPalette::Background);
style()->drawPrimitive(QStyle::PE_FrameFocusRect, &option, &painter, this);
}

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

QStylePainter painter(this);

...

painter.drawPrimitive(QStyle::PE_FrameFocusRect, option);

instead of

QPainter painter(this);

...

style()->drawPrimitive(QStyle::PE_FrameFocusRect, &option, &painter, this);

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 QCommonStyle.

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 primitive elements that are drawn by the drawPrimitive() function, so we need to reimplement that function. We need the following class declaration:

class CustomStyle : public QWindowsStyle
{
Q_OBJECT
public:
CustomStyle()
~CustomStyle() {}
void drawPrimitive(PrimitiveElement element, const QStyleOption *option,
QPainter *painter, const QWidget *widget) const;
};

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:

void CustomStyle::drawPrimitive(PrimitiveElement element, const QStyleOption *option,
QPainter *painter, const QWidget *widget) const
{
if (element == PE_IndicatorSpinUp || element == PE_IndicatorSpinDown) {
QPolygon points(3);
int x = option->rect.x();
int y = option->rect.y();
int w = option->rect.width() / 2;
int h = option->rect.height() / 2;
x += (option->rect.width() - w) / 2;
y += (option->rect.height() - h) / 2;
if (element == PE_IndicatorSpinUp) {
points[0] = QPoint(x, y + h);
points[1] = QPoint(x + w, y + h);
}
}

Notice that we don't use the 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 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:

QSpinBox *spinBox = qobject_cast<QSpinBox *>(widget);
if (spinBox) {

...

}

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 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.

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:

#include <QtGui>
#include "customstyle.h"
int main(int argc, char *argv[])
{
QApplication::setStyle(new CustomStyle);
QApplication app(argc, argv);
QSpinBox spinBox;
spinBox.show();
return app.exec();
}

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 -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 Qt Plugin documentation for more information on how to go about creating a style plugin.

Compile your plugin and put it into Qt's 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:

./myapplication -style custom

The application will use the look and feel from the custom style you implemented.

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 -reverse command-line option or to call QApplication::setLayoutDirection() in your main() function.

Here are some things to keep in mind when making a style work well in a right-to-left environment:

Styles in Item Views

The painting of items in views is performed by a delegate. Qt's default delegate, QStyledItemDelegate, is also used for calculating bounding rectangles of items, and their sub-elements for the various kind of item 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 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.

switch (element) {
case (PE_PanelItemViewItem): {
painter->save();
QPoint topLeft = option->rect.topLeft();
QPoint bottomRight = option->rect.topRight();
QLinearGradient backgroundGradient(topLeft, bottomRight);
backgroundGradient.setColorAt(0.0, QColor(Qt::yellow).lighter(190));
backgroundGradient.setColorAt(1.0, Qt::white);
painter->fillRect(option->rect, QBrush(backgroundGradient));
painter->restore();
break;
}
default:
QWindowsStyle::drawPrimitive(element, option, painter, widget);
}

The primitive element PE_PanelItemViewItem is responsible for painting the background of items, and is called from 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.

◆ drawComplexControl()

void QStyle::drawComplexControl ( ComplexControl  control,
const QStyleOptionComplex *  option,
QPainter *  painter,
const QWidget *  widget = 0 
) const
pure virtual

Draws the given control using the provided painter with the style options specified by option.

The widget argument is optional and can be used as aid in drawing the control.

The option parameter is a pointer to a QStyleOptionComplex object that can be cast to the correct subclass using the qstyleoption_cast() function. Note that the rect member of the specified option must be in logical coordinates. Reimplementations of this function should use visualRect() to change the logical coordinates into screen coordinates before calling the drawPrimitive() or drawControl() function.

The table below is listing the complex control elements and their associated style option subclass. The style options contain all the parameters required to draw the controls, including QStyleOption::state which holds the QStyle::StateFlag{style flags} that are used when drawing. The table also describes which flags that are set when casting the given option to the appropriate subclass.

◆ layoutSpacing()

int QStyle::layoutSpacing ( QSizePolicy::ControlType  control1,
QSizePolicy::ControlType  control2,
Qt::Orientation  orientation,
const QStyleOption *  option = 0,
const QWidget *  widget = 0 
) const

Returns the spacing that should be used between control1 and control2 in a layout.

Since
4.3

orientation specifies whether the controls are laid out side by side or stacked vertically. The option parameter can be used to pass extra information about the parent widget. The widget parameter is optional and can also be used if option is 0.

This function is called by the layout system. It is used only if PM_LayoutHorizontalSpacing or PM_LayoutVerticalSpacing returns a negative value.

For binary compatibility reasons, this function is not virtual. If you want to specify custom layout spacings in a QStyle subclass, implement a slot called layoutSpacingImplementation(). QStyle will discover the slot at run-time (using Qt's meta-object system) and direct all calls to layoutSpacing() to layoutSpacingImplementation().

QSizePolicy::ControlType  control2,
Qt::Orientation  orientation,
const QStyleOption *  option = 0,
const QWidget *  widget = 0 
) const
protectedslot

This slot is called by layoutSpacing() to determine the spacing that should be used between control1 and control2 in a layout.

Since
4.3

orientation specifies whether the controls are laid out side by side or stacked vertically. The option parameter can be used to pass extra information about the parent widget. The widget parameter is optional and can also be used if option is 0.

If you want to provide custom layout spacings in a QStyle subclass, implement a slot called layoutSpacingImplementation() in your subclass. Be aware that this slot will only be called if PM_LayoutHorizontalSpacing or PM_LayoutVerticalSpacing returns a negative value.

The default implementation returns -1.

◆ pixelMetric()

int QStyle::pixelMetric ( PixelMetric  metric,
const QStyleOption *  option = 0,
const QWidget *  widget = 0 
) const
pure virtual

Returns the value of the given pixel metric.

The specified option and widget can be used for calculating the metric. In general, the widget argument is not used. The option can be cast to the appropriate type using the qstyleoption_cast() function. Note that the option may be zero even for PixelMetrics that can make use of it. See the table below for the appropriate option casts:

Pixel Metric QStyleOption Subclass
PM_SliderControlThickness QStyleOptionSlider
PM_SliderLength QStyleOptionSlider
PM_SliderTickmarkOffset QStyleOptionSlider
PM_SliderSpaceAvailable QStyleOptionSlider
PM_ScrollBarExtent QStyleOptionSlider
PM_TabBarTabOverlap QStyleOptionTab
PM_TabBarTabHSpace QStyleOptionTab
PM_TabBarTabVSpace QStyleOptionTab
PM_TabBarBaseHeight QStyleOptionTab
PM_TabBarBaseOverlap QStyleOptionTab

Some pixel metrics are called from widgets and some are only called internally by the style. If the metric is not called by a widget, it is the discretion of the style author to make use of it. For some styles, this may not be appropriate.

◆ polish() [1/3]

void QStyle::polish ( QWidget *  )
virtual

Initializes the appearance of the given widget.

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

Note that the default implementation does nothing. Reasonable actions in this function might be to call the QWidget::setBackgroundMode() function for the widget. Do not use 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 future widgets, limited use of hard-coded customization is recommended.

Converts the given logicalValue to a pixel position.

The min parameter maps to 0, max maps to span and other values are distributed evenly in-between.

This function can handle the entire integer range without overflow, providing that span is less than 4096.

By default, this function assumes that the maximum value is on the right for horizontal items and on the bottom for vertical items. Set the upsideDown parameter to true to reverse this behavior.

◆ standardIcon()

QIcon QStyle::standardIcon ( StandardPixmap  standardIcon,

The standardIcon is a standard pixmap which can follow some existing GUI style or guideline. The option argument can be used to pass extra information required when defining the appropriate icon. The widget argument is optional and can also be used to aid the determination of the icon.

Warning
Because of binary compatibility constraints, this function is not virtual. If you want to provide your own icons in a QStyle subclass, reimplement the standardIconImplementation() slot in your subclass instead. The standardIcon() function will dynamically detect the slot and call it.

◆ subElementRect()

QRect QStyle::subElementRect ( SubElement  element,
const QStyleOption *  option,
const QWidget *  widget = 0 
) const
pure virtual

Returns the sub-area for the given element as described in the provided style option.

The returned rectangle is defined in screen coordinates.

The widget argument is optional and can be used to aid determining the area. The QStyleOption object can be cast to the appropriate type using the qstyleoption_cast() function. See the table below for the appropriate option casts:

Sub Element QStyleOption Subclass
SE_PushButtonContents QStyleOptionButton
SE_PushButtonFocusRect QStyleOptionButton
SE_CheckBoxIndicator QStyleOptionButton
SE_CheckBoxContents QStyleOptionButton
SE_CheckBoxFocusRect QStyleOptionButton

◆ unpolish() [1/2]

void QStyle::unpolish ( QWidget *  )
virtual

Uninitialize the given {widget}'s appearance.

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

Note that unpolish() will only be called if the widget is destroyed. This can cause problems in some cases, e.g, if you remove a widget from the UI, cache it, and then reinsert it after the style has changed; some of Qt's classes cache their widgets.

◆ visualAlignment()

Qt::Alignment QStyle::visualAlignment ( Qt::LayoutDirection  direction,
Qt::Alignment  alignment 
)
static

Transforms an alignment of Qt::AlignLeft or Qt::AlignRight without Qt::AlignAbsolute into Qt::AlignLeft or Qt::AlignRight with Qt::AlignAbsolute according to the layout direction.

The other alignment flags are left untouched.

If no horizontal alignment was specified, the function returns the default alignment for the given layout direction.
