In this article we will see how we can check if a certain region can be QRect or QRegion intersects 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.
In order to do this we use intersects method with the children region object of the spin box Syntax : children_region.intersects(rectangle) Argument : It takes QRect object as argument also it can take QRegion object Return : It returns bool
Below is the implementation
Python3
# 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 ):
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 )
# QRect
rectangle = QRect( 1 , 1 , 20 , 30 )
# checking if rectangle intersects the children region
check = children_region.intersects(rectangle)
# setting text to the label
label.setText("Intersects ? : " + str (check))
# 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 ())
