In this article we will see how we can check the certain point lies in the children region of spin box, children region holds the combined region occupied by the spin box’s children. In order to do this we use childrenRegion method.

Note : The point should be in the Spin box co-ordinates system

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

Syntax : children_region.contains(point)

Argument : It takes QPoint object as argument

Return : It returns bool object

Below is the implementation

# Write Python3 code here# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys
class Window(QMainWindow):
    def __init__(self):
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
        # calling method
        # showing all the widgets
        # 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)
        # setting geometry to the label
        label.setGeometry(100, 200, 200, 60)
        # getting bounding rectangle from the children region
        bounding_rectangle = children_region.contains(QPoint(10, 10))
        # setting text to the label
        label.setText("Point 10, 10 of spin box is in the children region "
                      "? " + str(bounding_rectangle))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
