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 :
