PyQt5 - 如何制作可编辑的组合框
在本文中,我们将看到如何创建一个组合框,以便用户通过键入来更改它的值。默认情况下,当我们创建组合框时,我们只能从下拉菜单中的选项中进行选择,尽管在可编辑组合框中我们可以自行设置文本。
为此,我们将使用setEditable
方法
Syntax : combo_box.setEditable(True)
Argument : It takes bool as argument
Action performed : It will combo box editable
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", "Legend Geek", "Ultra Legend Geek"]
# adding list of items to combo box
self.combo_box.addItems(geek_list)
# creating a editable combo box
self.combo_box.setEditable(True)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
