In this article we will see how we user entered item get added at the current selected position in the combo box i.e when user insert item in the editable combo box it get inserted at the position at which current selected item is in the drop down list, by default when user insert any item it get inserted at the bottom.
Note : When item get inserted at the selected position the original item of that position get over write.
In order to make combo box such that item inserted by user get added at the selected position in the drop down list we have to do the following –
1. Create a combo box
2. Make the combo box editable using setEditable method
3. Set insertion policy of combo box to insert at current
4. Create label
5. Retrieve the insertion policy and show it with the help of label
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): 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"] # adding list of items to combo box self.combo_box.addItems(geek_list) # creating editable combo box self.combo_box.setEditable(True) # setting insertion policy # new item will get added at selected place self.combo_box.setInsertPolicy(QComboBox.InsertAtCurrent) # 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, 100, 200, 30) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
