Synopsis

Functions

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, event):


    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, event):
{
    painter = QStylePainter(self)


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


    painter.drawPrimitive(QStyle.PE_FrameFocusRect, option)

PySide2.QtWidgets.QStylePainter.begin(pd, w)
Parameters
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 .

PySide2.QtWidgets.QStylePainter.begin(w)
Parameters

wPySide2.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 .

PySide2.QtWidgets.QStylePainter.drawComplexControl(cc, opt)
Parameters

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

PySide2.QtWidgets.QStylePainter.drawControl(ce, opt)
Parameters

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

Parameters

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.
