Note Each of the three following align examples starts with these unaligned

push buttons and repositions them in different ways. In practice, when you

create b uttons with

uicontrol and do not specify a Position, their location is

always

[20 20 60 20] (in pixels). That is, if you keep creating them with

default positions, they lie on top of one another.

Align Compon ents Horizon tally. The follow ing statement moves the push

buttons horizontally to the right of their bounding box. It does not alter their

vertical positions. The figure shows the original bounding box.

align([b1 b2 b3],'Right','None');

Align Com ponents Horizontally While Distributing Them Vertically.

The follow ing statement moves the push buttons horizontally to the center o f

their bounding box and adjusts their vertical placement. The

'Fixed' option

makes the distance between the boxes uniform. Specify the distance in points

(1 point = 1/72 inch). In this example, the distance is seven points. The push

buttons appear in the center of the original bounding box. The bottom push

button remains at the bottom of the original bounding box.

align([b1 b2 b3],'Center','Fixed', 7);
