[PyQt] problems with label

[swipis]

Hello

Have problem with label, trying to show label from another file but so far no luck. here is the code:

main.py

class mainWindow(QtGui.QWidget):
    def __init__(self):
        
        super(mainWindow, self).__init__()
        
        self.spdBar = SpeedPrg(self)
        
        #QtGui.QFontDatabase.addApplicationFont('/fonts/28_Days_Later.tff')

        self.initUi()

    def initUi(self):
        
        self.spdBar.setGeometry(10, 10, 300, 300)
        self.spdBar.setValue(.8)
        self.spdBar.setSpeedText('textas')
        
        # self.showFullScreen()
        pal = QPalette()
        pal.setColor(QPalette.Background, QtCore.Qt.black)
        self.setPalette(pal)
        self.setGeometry(100, 100, 800, 480)
        self.setWindowTitle('Window Title')

and here is second file with label in it:

class SpeedPrg(QtGui.QWidget):
    def __init__(self, parent=None):
        super(SpeedPrg, self).__init__(parent)
        
        self.lineWidth = 0
        self.setValue(0.0)

    def setValue(self, val):
        val = float(min(max(val, 0), 1))
        self._value = -270 * val
        self.update()

    def setLineWidth(self, lineWidth):
        self.lineWidth = lineWidth
        
    def setSpeedText(self, speedTxt):
        
        r = QtCore.QRect(self.rect())                               #get rectangle size
        p = r.center()                                              #get rect center
        
        lbl = QtGui.QLabel()
        lbl.setGeometry(p.x(),p.y(),50,50)                          #set label geometry
        lbl.setText(speedTxt)                                       #set label text
        lbl.setFont(QtGui.QFont('SansSerif',24))                    #set font
        pall = QtGui.QPalette()
        pall.setColor(QtGui.QPalette.WindowText, QtCore.Qt.white)   #set lable color
        lbl.setPalette(pall)

        print lbl.text()

How you can see I trying to call setSpeedText function from main.py (not sure I doing right or wrong, but I trying)
but output is:
