In this article we will see how we can get the next in focus chain widget of the spin box. Spin box consist of two child widgets one is line edit and other one is the arrow buttons. Focus is set widget by widget i.e focus chain there fore when spin box get focus its one child get focus before the another child.
In order to do this we use nextInFocusChain
method with the spin box object.
Syntax : spin_box.nextInFocusChain()
Argument : It takes no argument
Return : It returns QWidget 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 next in focus chain widget
value = self .spin.nextInFocusChain()
# setting text to the label
label.setText( "Next widget in focus chain : " + str (value))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
