PyQt5 – Finding the item through text in ComboBox

In this article we will see how we can find the item index with the help of text in it. We know we can add items with the help of addItems method, in order to find the item with the help of findText method.

Syntax : combo_box.findText(text) 

Argument : It takes string as argument. 

Return : It return integer i.e index of text if text doesn’t exist it return -1

Below is the implementation – 

Python3

# 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)

        # text
        text = "Legend Geek"

        # finding index of text
        index = self.combo_box.findText(text)

        # label to show index
        label = QLabel(text + " index : " + str(index), self)

        # setting geometry of label
        label.setGeometry(200, 200, 200, 30)

# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
