In this article we will see how we can get the child of the spin box at the given position inside the spin box, child are basically the component of the spin box, for example, the spin box main child is its QLineEdit which is used to see the value and set the value.
In order to do this we use childAt
method.
Syntax : spin_box.childAt(x, y)
Argument : It takes position as argument it can be x, y co-ordinates or the QPoint object
Return : It returns child at given position if there is no child it return None
Note : The co-ordinates are not of the window co-ordinate system they are in spin box co-ordinate system
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 prefix to spin
self .spin.setPrefix( "Prefix " )
# setting suffix to spin
self .spin.setSuffix( " Suffix" )
# creating a label
self .label = QLabel( "Label " , self )
# setting geometry to the label
self .label.setGeometry( 100 , 200 , 200 , 70 )
# getting the child at the point 10, 10
child = self .spin.childAt( 10 , 10 )
# setting text to the label
self .label.setText( str (child))
# making label multi line
self .label.setWordWrap( True )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
