PyQt5 QSpinBox – Setting rectangles to the Children Region

In this article we will see how we can sets the rectangle to the children region of spin box, children region holds the combined region occupied by the spin box’s children. In order to get the children region we use childrenRegion method. Children region consist of all the rectangles but if we set only some of the rectangles to it then it will change the region.

In order to do this we use setRects method with the children region object of the spin box

Syntax : children_region.setRects(rectangles)

Argument : It takes list of QRect as argument

Action Performed : It sets sets the region

Below is the implementation

# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui

import sys


class Window(QMainWindow):

    def __init__(self):
        super().__init__()

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 600, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()

        # method for widgets

    def UiComponents(self):
        # creating spin box
        self.spin = QSpinBox(self)

        # setting geometry to spin box
        self.spin.setGeometry(100, 100, 250, 40)

        # setting range to the spin box
        self.spin.setRange(0, 999999)

        # setting prefix to spin
        self.spin.setPrefix("Prefix ")

        # setting suffix to spin
        self.spin.setSuffix(" Suffix")

        # getting the children region
        children_region = self.spin.childrenRegion()

        # creating a label
        label = QLabel(self)
        label.setWordWrap(True)

        # setting geometry to the label
        label.setGeometry(100, 200, 200, 60)

        # getting rectangles that are inside the children region
        rectangles = children_region.rects()

        # setting rectangle
        children_region.setRects(rectangles)

        # setting text to the label
        label.setText("New region : " + str(children_region))


# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()
window.spin.setFocus()
# start the app
sys.exit(App.exec())

Output :
