Member Function Documentation

QProxyStyle::QProxyStyle(QStyle * style = 0)

Constructs a QProxyStyle object for overriding behavior in style or in the current application style if style is 0 (default). Normally style is 0, because you want to override behavior in the system style.

Ownership of style is transferred to QProxyStyle.

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.

void QProxyStyle::drawComplexControl(ComplexControl control, const QStyleOptionComplex * option, QPainter * painter, const QWidget * widget = 0) const [virtual]

Reimplemented from QStyle::drawComplexControl().

void QProxyStyle::drawControl(ControlElement element, const QStyleOption * option, QPainter * painter, const QWidget * widget = 0) const [virtual]

Reimplemented from QStyle::drawControl().

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

Reimplemented from QStyle::drawItemPixmap().

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

Reimplemented from QStyle::drawItemText().

void QProxyStyle::drawPrimitive(PrimitiveElement element, const QStyleOption * option, QPainter * painter, const QWidget * widget = 0) const [virtual]

Reimplemented from QStyle::drawPrimitive().

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

Reimplemented from QObject::event().

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

Reimplemented from QStyle::generatedIconPixmap().

SubControl QProxyStyle::hitTestComplexControl(ComplexControl control, const QStyleOptionComplex * option, const QPoint & pos, const QWidget * widget = 0) const [virtual]

Reimplemented from QStyle::hitTestComplexControl().

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

Reimplemented from QStyle::itemPixmapRect().

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

Reimplemented from QStyle::itemTextRect().

int QProxyStyle::layoutSpacingImplementation(QSizePolicy::ControlType control1, QSizePolicy::ControlType control2, Qt::Orientation orientation, const QStyleOption * option = 0, const QWidget * widget = 0) const [protected slot]

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 layoutSpacing() and combinedLayoutSpacing().

int QProxyStyle::pixelMetric(PixelMetric metric, const QStyleOption * option = 0, const QWidget * widget = 0) const [virtual]

Reimplemented from QStyle::pixelMetric().

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

Reimplemented from QStyle::polish().

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

Reimplemented from QStyle::polish().

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

Reimplemented from 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.

See also baseStyle().

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

Reimplemented from QStyle::sizeFromContents().

QIcon QProxyStyle::standardIconImplementation(StandardPixmap standardIcon, const QStyleOption * option, const QWidget * widget) const [protected slot]

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.

Note: Because of binary compatibility constraints, standardIcon() introduced in Qt 4.1 is not virtual. Therefore it must dynamically detect and call this slot. This default implementation simply calls standardIcon() with the given parameters.

See also standardIcon().

QPalette QProxyStyle::standardPalette() const [virtual]

Reimplemented from QStyle::standardPalette().

QPixmap QProxyStyle::standardPixmap(StandardPixmap standardPixmap, const QStyleOption * opt, const QWidget * widget = 0) const [virtual]

Reimplemented from QStyle::standardPixmap().

int QProxyStyle::styleHint(StyleHint hint, const QStyleOption * option = 0, const QWidget * widget = 0, QStyleHintReturn * returnData = 0) const [virtual]

Reimplemented from QStyle::styleHint().

QRect QProxyStyle::subControlRect(ComplexControl cc, const QStyleOptionComplex * option, SubControl sc, const QWidget * widget) const [virtual]

Reimplemented from QStyle::subControlRect().

QRect QProxyStyle::subElementRect(SubElement element, const QStyleOption * option, const QWidget * widget) const [virtual]

Reimplemented from QStyle::subElementRect().

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

Reimplemented from QStyle::unpolish().

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

Reimplemented from QStyle::unpolish().
