Lesson 7

 Today's widget is a scale, which we have turned inot a temperature scale.

The number were inverted so that 100 is at the top; it is placed in a vertical position.

(Indeed, that window can be manually widened, making it easier to move the scale 

around). The scale set provision adds the scale "to', not necessary for this design.

Also noteworthy, it is necessary ro convert the temperature reading scale.get() to a string 

before being able to print it. (Fourteen on its own gets printed just fine...)
