python - 将 QLCDNumber 文本右对齐

Question

我有 QGridLayout，其中插入 QLCDNumber，如下所示:

self.mainLayout.addWidget(display, 0, 0, 1 , 5)

一切都很好，但在窗口缩放时数字(默认为 0)从中心“移动”到右侧。有人可以给我提示如何防止 QLCDNumber 缩放并将其中的文本向右对齐吗？

尝试一下:

import sys
from PyQt5.QtCore    import *
from PyQt5.QtWidgets import *

class Window(QMainWindow):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

        self.lcd = QLCDNumber() 
        self.lcd.setFixedSize(150, 70)               # Set the size you want
        self.lcd.display(12345)      

        centralWidget = QWidget()                         
        self.setCentralWidget(centralWidget)

        self.mainLayout = QGridLayout(centralWidget)
        self.mainLayout.addWidget(self.lcd, 0, 0, Qt.AlignRight)  # Set the alignment option
        self.mainLayout.addWidget(QTextEdit("TextEdit..."), 1,0)
        self.mainLayout.addWidget(QPushButton("Button"), 2,0, Qt.AlignCenter)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex  = Window()
    ex.show()
    sys.exit(app.exec_())
