PyQt5 – 如何使不可编辑的组合框的文本居中对齐

在这篇文章中，我们将看到如何使组合框的文本居中对齐，并且组合框应保持不可编辑。默认情况下，组合框的文本是左对齐的，而且组合框本身没有任何对齐方法。

为了使文本居中对齐，我们必须做以下工作 –

1.创建一个组合框

2.从组合框中制作行编辑对象

3.将编辑行居中对齐

4.使行编辑成为可编辑的

注意： 由于组合框中的行编辑对象将成为可编辑的，因此需要使其成为不可编辑的

语法。

# getting the line edit of combo box
line_edit = self.combo_box.lineEdit()

# setting line edit alignment to the center
line_edit.setAlignment(Qt.AlignCenter)

# setting line edit to read only
line_edit.setReadOnly(True)

以下是实施情况

# 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 Sayian", "Super Sayian 2", "Super Sayian B"]
 
        # making it editable
        self.combo_box.setEditable(True)
 
        # adding list of items to combo box
        self.combo_box.addItems(geek_list)
 
        # getting the line edit of combo box
        line_edit = self.combo_box.lineEdit()
 
        # setting line edit alignment to the center
        line_edit.setAlignment(Qt.AlignCenter)
 
        # setting line edit to read only
        line_edit.setReadOnly(True)
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
