In this article we will see how we can get the parent of the spin box. Each widget has some parent for example Spin box’s child is line edit and line edit parent will be the spin box itself.
In order to do this we use parent
method with the spin box object.
Syntax : spin_box.parent()
Argument : It takes no argument
Return : It returns parent object
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( 1 , 999999 ) # setting prefix to spin self .spin.setPrefix( "PREFIX " ) # setting suffix to spin self .spin.setSuffix( " SUFFIX" ) # creating a label label = QLabel( self ) # making the label multi line label.setWordWrap( True ) # setting geometry to the label label.setGeometry( 100 , 200 , 200 , 60 ) # getting parent value = self .spin.parent() # setting text to the label label.setText( "Parent : " + str (value)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
Output :
