PyQt5 – 如何获得组合框的行编辑权

在这篇文章中，我们将看到如何获得组合框的行编辑，行编辑基本上是组合框的一个默认对象，我们在其中插入文本，它被组合框用来显示选择的选项，为了获得输入，我们可以在setLineEdit方法的帮助下获得组合框的行编辑对象，为了获得组合框的委托对象，我们将使用lineEdit方法

语法： combo_box.lineEdit()

参数： 不需要参数

返回：返回QLineEdit对象

以下是该方法的实现

# 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 = ["Saiyan", "Super Saiyan", "Super Saiyan 2", "Super Saiyan B"]
 
        # 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)
 
        # getting line edit
        line = self.combo_box.lineEdit()
 
        # creating label to show delegate
        label = QLabel("Line edit = " + str(line), self)
 
        # setting geometry of the label
        label.setGeometry(150, 100, 350, 30)
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
