PyQt5 – Setting limit to number of items in ComboBox

0 0 1 minute read

In this article we will see how we can set limit to the number of items in the combo box. When we create a combo box there is no limit set to the items we can add any number of items although sometimes condition arises to set the maximum limit to the items.

In order to set the maximum limit to the number of items we use setMaxCount method.

Syntax : combo_box.setMaxCount(n)

Argument : It takes integer as argument

Action performed : This will set maximum limit to the number of items in combo box

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) 
  
        # setting maximum number limit of items 
        self.combo_box.setMaxCount(2) 
  
# create pyqt5 app 
App = QApplication(sys.argv) 
  
# create the instance of our Window 
window = Window() 
  
# start the app 
sys.exit(App.exec())
