PyQt5 – 标签的对齐（）方法

在本文中，我们将看到有关alignment()方法。使用此方法也知道标签具有的对齐类型。我们使用setAlignment()方法来设置对齐方式， alignment()方法返回 Qt.Alignment 对象，它是setAlignment()方法的参数。

Syntax : label.alignment()

Argument : It takes no argument.

Return : It returns the Qt.Alignment object

代码 ：

# importing the required libraries
  
from PyQt5.QtCore import * 
from PyQt5.QtGui import * 
from PyQt5.QtWidgets import * 
import sys
  
  
class Window(QMainWindow):
    def __init__(self):
        super().__init__()
  
  
        # set the title
        self.setWindowTitle("Python")
  
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
  
        # creating a label widget
        self.label_1 = QLabel("old label ", self)
  
        # setting up the border
        self.label_1.setStyleSheet("border :3px solid black;")
  
        # setting the alignment of the label
        self.label_1.setAlignment(Qt.AlignRight)
  
        # getting he alignment of the label
        align = self.label_1.alignment()
  
        # printing the align of label
        print(align)
  
        # resizing the label
        self.label_1.resize(150, 40)
  
        # moving the label
        self.label_1.move(100, 100)
  
        # creating a new label widget
        self.label_2 = QLabel("new Label ", self)
  
        # setting up the border
        self.label_2.setStyleSheet("border :3px solid black;")
  
        # moving the label
        self.label_2.move(200, 200)
  
        # resizing the label
        self.label_2.resize(150, 40)
  
        # setting the alignment using label_1 alignment
        self.label_2.setAlignment(align)
  
        # 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 ：

PyQt5.QtCore.Qt.Alignment object at 0x0000021C0076E828
