Python Pyside2 QSlider через импорт класса

Question

Есть два файла где test.py(основной) и (win.py) дизайн приложения. В основном файле test.py у меня вот такой код, каким образом я могу выполнить метод test из импортированного класса Slider по нажатию на слайдер

class Example(QtWidgets.QWidget):

    def __init__(self):
        super().__init__()
        ui.setupUi(self)
        self.show()

    def test(self):
        print("Клик")

    def keyPressEvent(self, e):
        if e.key() == QtGui.Qt.Key_Escape:
            self.close()

if __name__ == '__main__':

    app = QtWidgets.QApplication(sys.argv)
    ui = Ui_Form()
    ex = Example()
    sys.exit(app.exec_())

А в win.py

class Slider(QSlider):

    def mousePressEvent(self, event):
        super(Slider, self).mousePressEvent(event)
        if event.button() == Qt.LeftButton:
            val = self.pixelPosToRangeValue(event.pos())
            self.setValue(val)

    def pixelPosToRangeValue(self, pos):
        opt = QStyleOptionSlider()
        self.initStyleOption(opt)
        gr = self.style().subControlRect(QStyle.CC_Slider, opt, QStyle.SC_SliderGroove, self)
        sr = self.style().subControlRect(QStyle.CC_Slider, opt, QStyle.SC_SliderHandle, self)

        if self.orientation() == Qt.Horizontal:
            sliderLength = sr.width()
            sliderMin = gr.x()
            sliderMax = gr.right() - sliderLength + 1
        else:
            sliderLength = sr.height()
            sliderMin = gr.y()
            sliderMax = gr.bottom() - sliderLength + 1;
        pr = pos - sr.center() + sr.topLeft()
        p = pr.x() if self.orientation() == Qt.Horizontal else pr.y()
        return QStyle.sliderValueFromPosition(self.minimum(), self.maximum(), p - sliderMin,
                                               sliderMax - sliderMin, opt.upsideDown)

class Ui_Form(object):


    def setupUi(self, Form):
        if not Form.objectName():
            Form.setObjectName(u"Form")
        Form.resize(286, 189)
        self.horizontalSlider = Slider(Form)
        self.horizontalSlider.setObjectName(u"horizontalSlider")
        self.horizontalSlider.setGeometry(QRect(60, 90, 160, 22))
        self.horizontalSlider.setOrientation(Qt.Horizontal)

        self.retranslateUi(Form)

        QMetaObject.connectSlotsByName(Form)
    # setupUi

    def retranslateUi(self, Form):
        Form.setWindowTitle(QCoreApplication.translate("Form", u"Form", None))
    # retranslateUi

Я отметил строки, в которые внес изменения. Поменяйте импорты под PySide2 !!!
