Last Updated : 25 Apr, 2025

In this article we will see how we can set the minimum length to the items of combo box i.e this property holds the minimum number of characters that should fit into the combo box. In order to do this we will use setMinimumContentsLength method, by default minimum length of combo box is 0.

Syntax : combo_box.setMinimumContentsLength(n) Argument : It takes integer as argument Return : void

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, 150, 30)

        # geek list
        geek_list = ["Sayian", "Super Sayian", "Super Sayian 2", "Super Sayian B"]

        # making it editable
        self.combo_box.setEditable(True)

        # adding list of items to combo box
        self.combo_box.addItems(geek_list)

        # setting minimum content length
        self.combo_box.setMinimumContentsLength(3)


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

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

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