PyQt5 – 将行编辑设置为 ComboBox

在本文中，我们将看到如何将行编辑设置为组合框，行编辑是 pyqt5 中的小部件。行编辑允许用户使用一组有用的编辑功能输入和编辑单行纯文本，包括撤消和重做、剪切和粘贴以及拖放。

为了将行编辑添加到组合框中，我们使用setLineEdit方法，这样我们可以使用行编辑小部件在组合框中输入项目，即使它是不可编辑状态。

Syntax : combo_box.setLineEdit(line_edit)

Argument : It takes QLineEdit object as argument

Action performed : This will add line edit to the combo box

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, 150, 30)
  
        # geek list
        geek_list = ["Sayian", "Super Saiyan", "Super Sayian 2"]
  
        # adding list of items to combo box
        self.combo_box.addItems(geek_list)
  
        # creating a line edit
        edit = QLineEdit(self)
  
        # setting line edit
        self.combo_box.setLineEdit(edit)
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
