成员函数

QProxyStyle::QProxyStyle(QStyle *style = Q_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.

参见 QStyleFactory::create().

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.

参见 setBaseStyle() and QStyle.

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

重新实现 QStyle::drawComplexControl().

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

重新实现 QStyle::drawControl().

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

重新实现 QStyle::drawItemPixmap().

[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

重新实现 QStyle::drawItemText().

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

重新实现 QStyle::drawPrimitive().

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

重新实现 QObject::event().

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

重新实现 QStyle::generatedIconPixmap().

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

重新实现 QStyle::hitTestComplexControl().

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

重新实现 QStyle::itemPixmapRect().

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

重新实现 QStyle::itemTextRect().

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

重新实现 QStyle::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.

参见 combinedLayoutSpacing().

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

重新实现 QStyle::pixelMetric().

[virtual] void QProxyStyle::polish(QWidget *widget)

重新实现 QStyle::polish().

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

重新实现 QStyle::polish().

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

重新实现 QStyle::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.

参见 baseStyle().

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

重新实现 QStyle::sizeFromContents().

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

重新实现 QStyle::standardIcon().

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.
