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 ())
