QStylePainter¶

PyQt5.QtWidgets.QStylePainter: Inherits from QPainter.

Description¶

The QStylePainter class is a convenience class for drawing QStyle elements inside a widget.

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:

# void MyWidget::paintEvent(QPaintEvent * /* event */)
# #! [0]
# {
# #! [2]
#     QPainter painter(this);
# #! [2]

#     QStyleOptionFocusRect option;
#     option.initFrom(this);
#     option.backgroundColor = palette().color(QPalette::Background);

# #! [3]
#     style()->drawPrimitive(QStyle::PE_FrameFocusRect, &option, &painter, this);
# #! [3]
# }

Example using QStylePainter:

# void MyWidget::paintEvent(QPaintEvent * /* event */)

# {

#     QStylePainter painter(this);
# #! [5]

#     QStyleOptionFocusRect option;
#     option.initFrom(this);
#     option.backgroundColor = palette().color(QPalette::Background);

# #! [7]
#     painter.drawPrimitive(QStyle::PE_FrameFocusRect, option);
# #! [7]
# }
