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 ())
