In this article we will see how we can get the number of maximum visible items of the combo box. By default at max 10 items are visible at a time in combo box drop down list although we can change this number. setMaxVisibleItems method is used to set the limit of maximum visible items. In order to get the maximum visible items number we use maxVisibleItems method
Syntax : combo_box.maxVisibleItems() Argument : It takes no argument Return : It returns integer
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) # setting max number visible limit self .combo_box.setMaxVisibleItems( 2 ) # getting maximum visible limit limit = self .combo_box.maxVisibleItems() # creating label to show the count label = QLabel(" Max visible limit = " + str (limit), self ) # setting label geometry 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 ()) |
