如何旋转 Label 或 PyQt5 中的按钮？

Question

I used QtDesigner to create a Gui. Now i want to rotate a button (m1 in my code) or label. i have read something about QTransform, but it didn't work, can anybody help me?

code: https://www.ppaste.org/zzwNqb7hI or https://www.ppaste.org/4oTcTykBt

Answer 1

To rotate Label You can use code as below:

        angle = 90  # What angle would you like to rotate
        self.pixmap = QPixmap("img\\label.png") # image for your label
        pixmap_rotated = self.pixmap.transformed(QTransform().rotate(angle),QtCore.Qt.SmoothTransformation)
        self.imageLabel.setPixmap(pixmap_rotated) # set rotated pixmap into your QLabel

As you didn't provide any reproducible code, it's just an example of how you could use QTransform to rotate QLabel.
