Member Function Documentation

QProxyStyle::QProxyStyle(QStyle *style = nullptr)

Constructs a QProxyStyle object for overriding behavior in the specified style, or in the default native style if style is not specified.

Ownership of style is transferred to QProxyStyle.

QProxyStyle::QProxyStyle(const QString &key)

Constructs a QProxyStyle object for overriding behavior in the base style specified by style key, or in the current application style if the specified style key is unrecognized.

See also QStyleFactory::create().

[virtual] QProxyStyle::~QProxyStyle()

Destroys the QProxyStyle object.

QStyle *QProxyStyle::baseStyle() const

Returns the proxy base style object. If no base style is set on the proxy style, QProxyStyle will create an instance of the application style instead.

See also setBaseStyle() and QStyle.

[override virtual] void QProxyStyle::drawComplexControl(QStyle::ComplexControl control, const QStyleOptionComplex *option, QPainter *painter, const QWidget *widget = nullptr) const

Reimplemented from QCommonStyle::drawComplexControl().

[override virtual] void QProxyStyle::drawControl(QStyle::ControlElement element, const QStyleOption *option, QPainter *painter, const QWidget *widget = nullptr) const

Reimplemented from QCommonStyle::drawControl().

[override virtual] void QProxyStyle::drawItemPixmap(QPainter *painter, const QRect &rect, int alignment, const QPixmap &pixmap) const

Reimplemented from QStyle::drawItemPixmap().

[override virtual] void QProxyStyle::drawItemText(QPainter *painter, const QRect &rect, int flags, const QPalette &pal, bool enabled, const QString &text, QPalette::ColorRole textRole = QPalette::NoRole) const

Reimplemented from QStyle::drawItemText().

[override virtual] void QProxyStyle::drawPrimitive(QStyle::PrimitiveElement element, const QStyleOption *option, QPainter *painter, const QWidget *widget = nullptr) const

Reimplemented from QCommonStyle::drawPrimitive().

[override virtual protected] bool QProxyStyle::event(QEvent *e)

Reimplemented from QObject::event().

[override virtual] QPixmap QProxyStyle::generatedIconPixmap(QIcon::Mode iconMode, const QPixmap &pixmap, const QStyleOption *opt) const

Reimplemented from QCommonStyle::generatedIconPixmap().

[override virtual] QStyle::SubControl QProxyStyle::hitTestComplexControl(QStyle::ComplexControl control, const QStyleOptionComplex *option, const QPoint &pos, const QWidget *widget = nullptr) const

Reimplemented from QCommonStyle::hitTestComplexControl().

[override virtual] QRect QProxyStyle::itemPixmapRect(const QRect &r, int flags, const QPixmap &pixmap) const

Reimplemented from QStyle::itemPixmapRect().

[override virtual] QRect QProxyStyle::itemTextRect(const QFontMetrics &fm, const QRect &r, int flags, bool enabled, const QString &text) const

Reimplemented from QStyle::itemTextRect().

[override virtual] int QProxyStyle::layoutSpacing(QSizePolicy::ControlType control1, QSizePolicy::ControlType control2, Qt::Orientation orientation, const QStyleOption *option = nullptr, const QWidget *widget = nullptr) const

Reimplemented from QCommonStyle::layoutSpacing().

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

The default implementation returns -1.

See also combinedLayoutSpacing().

[override virtual] int QProxyStyle::pixelMetric(QStyle::PixelMetric metric, const QStyleOption *option = nullptr, const QWidget *widget = nullptr) const

Reimplemented from QCommonStyle::pixelMetric().

Reimplemented from QCommonStyle::polish().

[override virtual] void QProxyStyle::polish(QPalette &pal)

Reimplemented from QCommonStyle::polish().

[override virtual] void QProxyStyle::polish(QApplication *app)

Reimplemented from QCommonStyle::polish().

void QProxyStyle::setBaseStyle(QStyle *style)

Sets the base style that should be proxied.

Ownership of style is transferred to QProxyStyle.

If style is zero, a desktop-dependant style will be assigned automatically.

See also baseStyle().

[override virtual] QSize QProxyStyle::sizeFromContents(QStyle::ContentsType type, const QStyleOption *option, const QSize &size, const QWidget *widget) const

Reimplemented from QCommonStyle::sizeFromContents().

[override virtual] QIcon QProxyStyle::standardIcon(QStyle::StandardPixmap standardIcon, const QStyleOption *option = nullptr, const QWidget *widget = nullptr) const

Returns an icon for the given standardIcon.

Reimplement this slot to provide your own icons in a QStyle subclass. The option argument can be used to pass extra information required to find the appropriate icon. The widget argument is optional and can also be used to help find the icon.
