    Demo Element Justification In A Window Using Stretch Elements

    How to Justify elements on 1 row to be left, right or left, middle, right

    Additionally, locate these buttons at the bottom of the screen


    To get 2 buttons to be all the way to the left and to the far right, then
        you want to place a Stretch element between them that expands
    If you want a third button that is centered, then add TWO Stretch elements, one
        on each side of the middle one
