Detailed Description

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

CopperSpice contains a set of QStyle subclasses which emulate the styles of the different platforms such as QWindowsStyle, QFusionStyle, QMacStyle, etc. By default these styles are built into CsGui. Styles can also be made available as plugins.

The built in widgets use QStyle to perform nearly all of their drawing, ensuring they look exactly like the equivalent native widgets. The diagram shows a QComboBox in nine different styles.

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 windows

If no style is specified, CopperSpice 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() method.

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:

An enum value specifying which graphical element to draw
A QStyleOption specifying how and where to render that element
A QPainter that should be used to draw the element
A QWidget on which the drawing is performed (optional)

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 is not 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 CopperSpice provides the QStylePainter class, which combines a QStyle, a QPainter, and a QWidget. This makes it possible to write the following.

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 CopperSpice 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 CopperSpice requires its styles to be QCommonStyles.

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
{
  CS_OBJECT(CustomStyle)
 
  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 is 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);
            points[2] = QPoint(x + w / 2, y);
 
        } else { // PE_SpinBoxDown
            points[0] = QPoint(x, y);
            points[1] = QPoint(x + w, y);
            points[2] = QPoint(x + w / 2, y + h);
        }
 
        if (option->state & State_Enabled) {
            painter->setPen(option->palette.mid().color());
            painter->setBrush(option->palette.buttonText());
 
        } else {
            painter->setPen(option->palette.buttonText().color());
            painter->setBrush(option->palette.mid());
        }
 
        painter->drawPolygon(points);
 
    } else {
        QWindowsStyle::drawPrimitive(element, option, painter, widget);
    }
}

Notice that we do not 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 is not 0 and that it is of the correct type before using it.

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

When implementing a custom style, you can not assume that the widget is a QSpinBox just because the enum value is called PE_IndicatorSpinUp or PE_IndicatorSpinDown.

Warning: CopperSpice 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. 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, however by calling it before the constructor, you ensure the user's preference, set using the -style command-line option, is respected.

A style may be implemented as a plugin. Styles created as plugins are loaded as shared objects at runtime. Refer to Creating Plugins for more information on creating a plugin.

Style plugins should be located in the plugins/styles directory. To use your new style with an existing application, start the application with the following argument:

./myapplication -style custom

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:

subControlRect() and subElementRect() return rectangles in screen coordinates
QStyleOption::direction indicates in which direction the item should be drawn in
If a style is not right-to-left aware it will display items as if it were left-to-right
visualRect(), visualPos(), and visualAlignment() are helpful functions that will translate from logical to screen representations.
alignedRect() will return a logical rect aligned for the current direction

Styles in Item Views

The painting of items in views is performed by a delegate. the CopperSpice 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-architecture-c "Model/View Architecture".

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.

		Qt::Orientation	orientation,
		QStyleOption *	option = `nullptr`,
		QWidget *	widget = `nullptr`
	)		const

Returns the spacing that should be used between controls1 and controls2 in a layout. These two controls are a bitwise OR of zero or more control types. The 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 a nullptr.

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

	)		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 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.

If a primitive element is not listed here, it is because it uses a plain QStyleOption object.

Primitive Element	QStyleOption Subclass	Style Flag	Remark
PE_FrameFocusRect	QStyleOptionFocusRect	State_FocusAtBorder	Whether the focus is the border or inside the widget.
PE_IndicatorCheckBox	QStyleOptionButton	State_NoChange	Indicates a "tri-state" checkbox.
PE_IndicatorCheckBox	QStyleOptionButton	State_On	Indicates the indicator is checked.
PE_IndicatorRadioButton	QStyleOptionButton	State_On	Indicates that a radio button is selected.
State_NoChange	Indicates a "tri-state" controller.
State_Enabled	Indicates the controller is enabled.
PE_IndicatorBranch	QStyleOption	State_Children	Indicates that the control for expanding the tree to show child items, should be drawn.
		State_Item	Indicates that a horizontal branch (to show a child item), should be drawn.
		State_Open	Indicates that the tree branch is expanded.
		State_Sibling	Indicates that a vertical line (to show a sibling item), should be drawn.
PE_IndicatorHeaderArrow	QStyleOptionHeader	State_UpArrow	Indicates that the arrow should be drawn up, otherwise it should be down.

QPixmap QStyle::generatedIconPixmap	(	QIcon::Mode	iconMode,
		const QPixmap &	pixmap,
		const QStyleOption *	option
	)		const

pure virtual

Returns a copy of the given pixmap styled to conform to the specified iconMode and taking into account the palette specified by option. The option parameter can pass extra information, but it must contain a palette.

Not all pixmaps will conform, in which case the returned pixmap is a plain copy.

SubControl QStyle::hitTestComplexControl	(	ComplexControl	control,
		const QStyleOptionComplex *	option,
		const QPoint &	position,
		const QWidget *	widget = `nullptr`
	)		const

pure virtual

Returns the sub control at the given position in the given complex control (with the style options specified by option). The position is expressed in screen coordinates.

The option argument is a pointer to a QStyleOptionComplex object (or one of its subclasses). The object can be cast to the appropriate type using the qstyleoption_cast() function. See drawComplexControl() for details. The widget argument is optional and can contain additional information for the function.

QRect QStyle::itemPixmapRect	(	const QRect &	rect,
		int	alignment,
		const QPixmap &	pixmap
	)		const

virtual

Returns the area within the given rect in which to draw the specified pixmap according to the defined alignment.

Reimplemented in QGtkStyle::itemPixmapRect(), QFusionStyle::itemPixmapRect(), QProxyStyle::itemPixmapRect()

QRect QStyle::itemTextRect	(	const QFontMetrics &	metrics,
		const QRect &	rect,
		int	alignment,
		bool	enabled,
		const QString &	text
	)		const

virtual

Returns the area within the given rect in which to draw the provided text according to the specified font metrics and alignment. The enabled parameter indicates whether or not the associated item is enabled.

If the given rectangle is larger than the area needed to render the text, the rectangle that is returned will be offset within rectangle according to the specified alignment. For example, if alignment is Qt::AlignCenter, the returned rectangle will be centered within rectangle. If the given rectangle is smaller than the area needed, the returned rectangle will be the smallest rectangle large enough to render the text.

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

pure virtual

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

int QStyle::pixelMetric	(	PixelMetric	metric,
		const QStyleOption *	option = `nullptr`,
		const QWidget *	widget = `nullptr`
	)		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. 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.

The option can be cast to the appropriate type using the qstyleoption_cast() method. It may also be zero even for PixelMetrics that can make use of it. Refer to the following table for the data type corresponding to each pixel metric.

Pixel Metric	QStyleOption Subclass
PM_SliderControlThickness	QStyleOptionSlider

void QStyle::polish ( QWidget * widget )

virtual

Initializes the appearance of the given widget. This method 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.

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 the CopperSpice style engine it is rarely necessary to implement this function; reimplement drawItemPixmap(), drawItemText(), drawPrimitive(), etc. instead.

The QWidget::inherits() method 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.

const QStyle * QStyle::proxy ( ) const

This function returns the current proxy for this style. By default most styles will return themselves. However when a proxy style is in use, it will allow the style to call back into its proxy.

QSize QStyle::sizeFromContents	(	ContentsType	type,
		const QStyleOption *	option,
		const QSize &	contentsSize,
		const QWidget *	widget = `nullptr`
	)		const

pure virtual

Returns the size of the element described by the specified option and type, based on the provided contentsSize.

The option argument is a pointer to a QStyleOption or one of its subclasses. The option can be cast to the appropriate type using the qstyleoption_cast() function. The widget is an optional argument and can contain extra information used for calculating the size.

See the table below for the appropriate option casts:

Contents Type	QStyleOption Subclass
CT_PushButton	QStyleOptionButton
CT_CheckBox	QStyleOptionButton
CT_RadioButton	QStyleOptionButton
CT_ToolButton	QStyleOptionToolButton
CT_ComboBox	QStyleOptionComboBox

int QStyle::sliderPositionFromValue	(	int	min,
		int	max,
		int	logicalValue,
		int	span,
		bool	upsideDown = `false`
	)

static

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 method 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.

int QStyle::sliderValueFromPosition	(	int	min,
		int	max,
		int	position,
		int	span,
		bool	upsideDown = `false`

QIcon QStyle::standardIcon	(	StandardPixmap	standardIcon,
		const QStyleOption *	option = `nullptr`,
		const QWidget *	widget = `nullptr`
	)		const

pure virtual

Returns an icon for the given 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.

QPalette QStyle::standardPalette ( ) const

virtual

Returns the style's standard palette.

Note that on systems that support system colors, the style's standard palette is not used. In particular, the Windows XP, Vista, and Mac styles do not use the standard palette, but make use of native theme engines. With these styles, you should not set the palette with QApplication::setStandardPalette().

void QStyle::unpolish ( QApplication * application )

virtual

Uninitialize the given application.

void QStyle::unpolish ( QWidget * widget )

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 the CopperSpice classes cache their widgets.
