Hello and sorry but i don't understand the mistacke:

I do as follow:

    class PictureFrame(QtGui.QFrame): 

        def __init__(self, parent = None):
            QFrame.__init__(self, parent)
            self.picture = QtGui.QPicture()
        
        def paintEvent(self, event):
            p = QPainter(self)   
            p.drawPicture(0, 0, self.picture)
              
    @pyqtSignature("")
    def on_pushButton_5_clicked(self):
        gr = QtGui.QPainter(self.frame1.picture)
        gr.setPen(QtGui.QPen(QtCore.Qt.black, 1, QtCore.Qt.SolidLine))
        gr.drawLine(70,50,740,50)
        gr.drawLine(70,60, 70, 400)
        gr.drawLine(70, 230,740, 230)
