[PyQt] Qt Designer - Making a Font with a border

[Alfalfa]

This is what I use for blur effect on a pixmap. Perhaps you can apply it to a label with QGraphicsDropShadowEffect instead. I only tried with pixmaps, so you might be able to get it to work without the graphics scene and the painter, as shown here: https://wiki.qt.io/Text_Shadows_in_QLabel_Snippets

    def blur(self, pixmap):
        effect = QtWidgets.QGraphicsBlurEffect()
        scene = QtWidgets.QGraphicsScene()
        item = QtWidgets.QGraphicsPixmapItem(pixmap)
        scene.addItem(item)
        item.setGraphicsEffect(effect)
        image = pixmap.toImage()
        image.fill(QtCore.Qt.transparent)
        painter = QtGui.QPainter(image)
        scene.render(painter)
        painter.end()
        return QtGui.QPixmap(image)
