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
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 )
# 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 ())
