In this article we will see how we can get united with the children region of spin box and another region, children region holds the combined region occupied by the spin box’s children. In order to get the children region we use childrenRegion method. United region will be the union of the children region and the children region
In order to do this we use united method with the children region object of the spin box
Syntax : children_region.united(rectangle)
Argument : It takes QRect as argument also it can take QRegion
Return : It returns None
Below is the implementation
# 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( 200 , 200 , 40 , 50 )
# getting united region with the children region
children_region = children_region.united(rectangle)
# setting text to the label
label.setText("United region : " + str (children_region.rects()))
# 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 ())
