\class QStylePainter
\brief The QStylePainter class is a convenience class for drawing QStyle
elements inside a widget.
\ingroup appearance
\ingroup painting
\inmodule QtWidgets
QStylePainter extends QPainter with a set of high-level \c
draw...() functions implemented on top of QStyle's API. The
advantage of using QStylePainter is that the parameter lists get
considerably shorter. Whereas a QStyle object must be able to
draw on any widget using any painter (because the application
normally has one QStyle object shared by all widget), a
QStylePainter is initialized with a widget, eliminating the need
to specify the QWidget, the QPainter, and the QStyle for every
function call.
Example using QStyle directly:
\snippet styles/styles.cpp 1
Example using QStylePainter:
\snippet styles/styles.cpp 0
\snippet styles/styles.cpp 4
\snippet styles/styles.cpp 6
\sa QStyle, QStyleOption
*/
/*!
\fn QStylePainter::QStylePainter()
Constructs a QStylePainter.
*/
/*!
\fn QStylePainter::QStylePainter(QWidget *widget)
Construct a QStylePainter using widget \a widget for its paint device.
*/
/*!
\fn QStylePainter::QStylePainter(QPaintDevice *pd, QWidget *widget)
Construct a QStylePainter using \a pd for its paint device, and
attributes from \a widget.
*/
/*!
\fn bool QStylePainter::begin(QWidget *widget)
Begin painting operations on the specified \a widget.
Returns \c true if the painter is ready to use; otherwise returns \c false.
This is automatically called by the constructor that takes a QWidget.
*/
/*!
\fn bool QStylePainter::begin(QPaintDevice *pd, QWidget *widget)
\overload
Begin painting operations on paint device \a pd as if it was \a
widget.
This is automatically called by the constructor that
takes a QPaintDevice and a QWidget.
*/
/*!
\fn void QStylePainter::drawPrimitive(QStyle::PrimitiveElement pe, const QStyleOption &option)
Use the widget's style to draw a primitive element \a pe specified by QStyleOption \a option.
\sa QStyle::drawPrimitive()
*/
/*!
\fn void QStylePainter::drawControl(QStyle::ControlElement ce, const QStyleOption &option)
Use the widget's style to draw a control element \a ce specified by QStyleOption \a option.
\sa QStyle::drawControl()
*/
/*!
\fn void QStylePainter::drawComplexControl(QStyle::ComplexControl cc,
const QStyleOptionComplex &option)
Use the widget's style to draw a complex control \a cc specified by the
QStyleOptionComplex \a option.
\sa QStyle::drawComplexControl()
*/
/*!
\fn void QStylePainter::drawItemText(const QRect &rect, int flags, const QPalette &pal,
bool enabled, const QString &text,
QPalette::ColorRole textRole = QPalette::NoRole)
Draws the \a text in rectangle \a rect and palette \a pal.
The text is aligned and wrapped according to \a
flags.
The pen color is specified with \a textRole. The \a enabled bool
indicates whether or not the item is enabled; when reimplementing
this bool should influence how the item is drawn.
\sa QStyle::drawItemText(), Qt::Alignment
*/
/*!
\fn void QStylePainter::drawItemPixmap(const QRect &rect, int flags, const QPixmap &pixmap)
Draws the \a pixmap in rectangle \a rect.
The pixmap is aligned according to \a flags.
\sa QStyle::drawItemPixmap(), Qt::Alignment
*/
/*!
\fn QStyle *QStylePainter::style() const
Return the current style used by the QStylePainter.
