In this article we will see how we can get the current index of the selected item the combo box. In order to do this we will use the currentIndex method.
Syntax : combo_box.currentIndex()
Argument : It takes no argument
Return : It return integer i.e index of selected item
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 count 5. Inside the action get the index of current item selected in combo box with the help of currentIndex method and store it in variable 6. Show the index in label with the help of setText 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("Show 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 )
def find( self ):
# finding the current item index in combo box
index = self .combo_box.currentIndex()
# showing content on the screen through label
self .label.setText("Index : " + str (index))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
