PyQt5 - 如何在 ComboBox 中进行重复插入
在本文中,我们将了解如何在组合框中允许重复插入。默认情况下不允许重复插入,尽管可以以编程方式将重复项插入组合框中,但用户不能插入重复值。
为了允许重复插入,我们将使用setDuplicatesEnabled
方法
Syntax : combo_box.setDuplicatesEnabled(True)
Argument : It takes bool as argument
Action performed : It will allow user to make duplicate insertions
下面是实现——
# 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)
# making it editable combo box
self.combo_box.setEditable(True)
# allowing duplication of items
# setting duplicates = True
self.combo_box.setDuplicatesEnabled(True)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
