PyQt5 – How to know maximum number of items limit in ComboBox

  • Last Updated : 22 Apr, 2020
Geek Week

In this article we will see how we can know maximum number limit 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.

In order to know the max limit we use maxCount method.

Syntax : combo_box.maxCount()

Argument : It takes no argument

Return : It returns integer

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):
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
        # calling method
        # showing all the widgets
    # 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
        # setting maximum number limit of items
        # getting max number limit
        limit = self.combo_box.maxCount()
        # creating label to show the limit
        label = QLabel("Max limit of items : " + str(limit), self)
        # setting geometry of label
        label.setGeometry(200, 200, 250, 30)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
