Qt :如何在QVBoxLayout中替换QTextEdit对齐方式？

#include <QtWidgets>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QWidget window;
    QVBoxLayout *layout = new QVBoxLayout(&window);

    QTextEdit *textEdit = new QTextEdit(&window);
    textEdit->setAlignment(Qt::AlignCenter); // 设置初始对齐方式为居中
    layout->addWidget(textEdit);

    // 替换对齐方式为右对齐
    textEdit->setAlignment(Qt::AlignRight);

    window.show();

    return app.exec();
}
