Lesson 6

 The code on Lesson 6 - for a radio box - looks a tad complex; but when all is 

said and done, the code yells "Hamburger' to the cook, so maybe not that

daunting after all.

The radiobox is a pre-defined widget that only allows the user to make one choice

from many possibilities. Our example offer both text and image versions of the choices

in question. The order() function, defined prior to the window, is a loop that goes

through the index numbers on the food array. One needs to create an x variable for this

to work, and it is an integer variable. The food choices  in the array are strings,

and the images, PhotoImage, as with previous widgets.

The pack() function here uses anchor(W) -west - for which I am adding a reference

scheme from another tutorial.
