PyQt5 – Label的alignment()方法

在这篇文章中，我们将看到alignment()方法。这个方法是用来知道标签的对齐方式的。我们使用setAlignment()方法来设置对齐方式，alignment()方法返回Qt.Alignment对象，这是setAlignment()方法的参数。

语法： label.alignment()

参数： 它不需要参数。

返回： 它返回Qt.Alignment对象。

代码。

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:
