PyQt5 – How know the insertion policy of the ComboBox
In this article we will see how we can know the insertion policy of the combo box. By default it insert at the bottom although we can change it any time. Insertion policy tells where will the new item when inserted by the user will get stored.
In order know the insertion policy we use insertPolicy method.
Syntax : combo_box.insertPolicy()
Argument : It takes no argument
Return : It returns InsertPolicy object (prints 3 for insert at bottom)
Below is the implementation
# importing librariesfrom PyQt5.QtWidgets import * from PyQt5 import QtCore, QtGuifrom 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) # creating editable combo box self.combo_box.setEditable(True) # getting current insertion policy policy = self.combo_box.insertPolicy() # creating label to print the policy label = QLabel("Insertion policy = " + str(policy), self) # setting geometry of the label label.setGeometry(200, 200, 200, 30) # create pyqt5 appApp = QApplication(sys.argv) # create the instance of our Windowwindow = Window() # start the appsys.exit(App.exec()) |
