In this article we will see how we can change the content of item at the specific index in combo box. In order to do this we will use setItemText
method.
Syntax : combo_box.setItemText(index, item)
Argument : It takes two argument one is integer and second is string
Action performed : This will change the content at that specific index
Steps for implementation –
1. Create a combo box
2. Add items to combo box
3. Create push button
4. Add action to the push button
5. Create label to show previous text
5. Inside the action change the content of item at given index using setItemText method
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 a combo box widget
self .combo_box = QComboBox( self )
# setting geometry of combo box
self .combo_box.setGeometry( 200 , 150 , 120 , 30 )
# geek list
geek_list = [ "Geek" , "Geeky Geek" , "Legend Geek" , "Ultra Legend Geek" ]
# adding list of items to combo box
self .combo_box.addItems(geek_list)
# creating push button
button = QPushButton( "Change content " , self )
print ( self .combo_box.count())
# adding action to button
button.pressed.connect( self .find)
# creating label
self .label = QLabel( self )
# setting geometry of the label
self .label.setGeometry( 200 , 200 , 200 , 30 )
# old content at index 2
content = self .combo_box.itemText( 2 )
# showing the old content
self .label.setText( "old content : content" )
def find( self ):
# index
index = 2
# changing the content
self .combo_box.setItemText(index, "New data" )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
