In this article we will see how we can find the child of spin box using the child ID, we can get the child id using winId method with the object of child. Spin box is the parent widget it has child like line edit widget and up and down button.
In order to do this we use find method Syntax : spin_box.find(id) Argument : It takes child id as argument Return : It returns the child object
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")
# ensuring spin box is polished
i_d = self .spin.lineEdit().winId()
# getting child using ID
child = self .spin.find(i_d)
# creating a label
label = QLabel( self )
# making it multi line
label.setWordWrap( True )
# setting its geometry
label.setGeometry( 100 , 200 , 200 , 60 )
# setting text to the label
label.setText( str (child))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
