Detailed Description#

QStylePainter extends QPainter with a set of high-level 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:

def paintEvent(self, */):

    painter = QPainter(self)

    option = QStyleOptionFocusRect()
    option.initFrom(self)
    option.backgroundColor = palette().color(QPalette.Background)

    style().drawPrimitive(QStyle.PE_FrameFocusRect, option, painter, self)

Example using QStylePainter :

def paintEvent(self, */):        painter = QStylePainter(self)

option = QStyleOptionFocusRect()
option.initFrom(self)
option.backgroundColor = palette().color(QPalette.Background)

painter.drawPrimitive(QStyle.PE_FrameFocusRect, option)

class PySide6.QtWidgets.QStylePainter#

PySide6.QtWidgets.QStylePainter(pd, w)

PySide6.QtWidgets.QStylePainter(w)

Parameters

pd – PySide6.QtGui.QPaintDevice
w – PySide6.QtWidgets.QWidget

Constructs a QStylePainter .

Construct a QStylePainter using pd for its paint device, and attributes from widget.

Construct a QStylePainter using widget widget for its paint device.

PySide6.QtWidgets.QStylePainter.begin(pd, w)#

Parameters

pd – PySide6.QtGui.QPaintDevice
w – PySide6.QtWidgets.QWidget

Return type

bool

This is an overloaded function.

Begin painting operations on paint device pd as if it was widget.

This is automatically called by the constructor that takes a QPaintDevice and a QWidget .

PySide6.QtWidgets.QStylePainter.begin(w)

Parameters: w – PySide6.QtWidgets.QWidget
Return type: bool

Begin painting operations on the specified widget. Returns true if the painter is ready to use; otherwise returns false.

This is automatically called by the constructor that takes a QWidget .

PySide6.QtWidgets.QStylePainter.drawComplexControl(cc, opt)#

Parameters

cc – ComplexControl
opt – PySide6.QtWidgets.QStyleOptionComplex

Use the widget’s style to draw a complex control cc specified by the QStyleOptionComplex option.

drawComplexControl()

PySide6.QtWidgets.QStylePainter.drawControl(ce, opt)#

Parameters

ce – ControlElement
opt – PySide6.QtWidgets.QStyleOption

Use the widget’s style to draw a control element ce specified by QStyleOption option.

drawControl()

PySide6.QtWidgets.QStylePainter.drawItemPixmap(r, flags, pixmap)#

Parameters

r – PySide6.QtCore.QRect
flags – int
pixmap – PySide6.QtGui.QPixmap

Draws the pixmap in rectangle rect. The pixmap is aligned according to flags.

PySide6.QtWidgets.QStylePainter.drawItemText(r, flags, pal, enabled, text[, textRole=QPalette.NoRole])#

Parameters

r – PySide6.QtCore.QRect
flags – int
pal – PySide6.QtGui.QPalette
enabled – bool
text – str
textRole – ColorRole

Draws the text in rectangle rect and palette pal. The text is aligned and wrapped according to flags.

The pen color is specified with textRole. The enabled bool indicates whether or not the item is enabled; when reimplementing this bool should influence how the item is drawn.

PySide6.QtWidgets.QStylePainter.drawPrimitive(pe, opt)#

Parameters

pe – PrimitiveElement
opt – PySide6.QtWidgets.QStyleOption

Use the widget’s style to draw a primitive element pe specified by QStyleOption option.
