如何使用样式表更改 PyQt 按钮的 position？

Question

I am familiar with CSS so it would be awesome if I could use it. The problem I have is when positioning using CSS.

This is the python code:

from PyQt5 import QtCore, QtGui, QtWidgets


f=open("style.css", "r")
stylesheet = f.read()
f.close()


class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(1084, 650)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.saveButton = QtWidgets.QPushButton(self.centralwidget)
        self.saveButton.setObjectName("saveButton")
        MainWindow.setCentralWidget(self.centralwidget)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "Wallpaper"))
        self.saveButton.setText(_translate("MainWindow", "Save"))





if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    app.setStyleSheet(stylesheet)
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

And this is css code:

QPushButton{
    background-color: #4e4e4e;
    color: #ffffff;
    position: absolute;
    top: 100px;
    left: 100px;
}

TL; DR; No, you cannot change the position of a widget using Qt Style Sheet.

---

Although the "position" property exists in the Qt Style Sheet, it is not used to move widgets, but rather to establish the position of the internal elements of the widget with respect to the same widget, such as the "down-button" position of the QSpinBox with respect to the QSpinBox,
