+When refueling, the quantity is read in via the text() method of the LineEdit widget and converted into the required data type using //float//.
+<code python>
+    def bRefuel_Command(self):
+        # Input from the GUI
+        amount = float(self.leAmount.text())
+        # Processing
+        self.car1.refuel(amount)
+        # Output
+        self.show()
+</code>
+Then, according to the IPO principle, the entered amount is processed in the //refuel()// method.
+Finally, the result is output with a separate method //show()//. The values for license plate, tank contents and mileage are retrieved via the get() methods of the class car and passed to the setText() methods of the widgets leLicenseplate, leTankcontent and leMileage:
+<code python>
+    def show(self):
+        self.leLicenseplate.setText(self.car1.get_licenseplate())
+        self.leTankcontent.setText(self.car1.get_tankcontent())
+        self.leMileage.setText(self.car1.get_mileage())
+        self.lCar.move(x = self.car1.get_mileage(), y = 160)
+</code>
+The label widget //lCar// has been assigned a car image via the //Pixmap// attribute in the object inspector. The //move()// method sets the x position of the car to the mileage.
