PyQt5 – 如何对齐标签的文本

在本文中，我们将了解如何在 PyQt5 应用程序中对齐标签文本，我们可以通过左、右和居中三种不同的方式对齐文本。
句法 ：

label.setAlignment(QtCore.Qt.AlignLeft)
label.setAlignment(QtCore.Qt.AlignCenter)
label.setAlignment(QtCore.Qt.AlignRight)

为了使用它，我们必须从 PyQt5 导入 Qtcore

from PyQt5 import QtCore

下面是实现：

Python3

# importing the required libraries
 
from PyQt5.QtWidgets import *
from PyQt5 import QtCore
from PyQt5.QtGui import *
import sys
 
class Window(QMainWindow):
    def __init__(self):
        super().__init__()
 
        # set the title
        self.setWindowTitle("Label")
 
        # setting  the geometry of window
        self.setGeometry(0, 0, 400, 300)
 
        # creating a label widget
        self.label_1 = QLabel('Left', self)
 
        # moving position
        self.label_1.move(100, 100)
 
        # setting up border
        self.label_1.setStyleSheet("border: 1px solid black;")
 
        # setting alignment to left
        self.label_1.setAlignment(QtCore.Qt.AlignLeft)
 
        # creating a label widget
        self.label_2 = QLabel('Center', self)
 
        # moving position
        self.label_2.move(100, 130)
 
        # setting up border
        self.label_2.setStyleSheet("border: 1px solid black;")
 
        # setting alignment to center
        self.label_2.setAlignment(QtCore.Qt.AlignCenter)
 
        # creating a label widget
        self.label_3 = QLabel('Right', self)
 
        # moving position
        self.label_3.move(100, 160)
 
        # setting up border
        self.label_3.setStyleSheet("border: 1px solid black;")
 
        # setting alignment to right
        self.label_3.setAlignment(QtCore.Qt.AlignRight)
 
        # show all the widgets
        self.show()
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出 ：
