Compose and Code GUIs with Interactive Tools
The buttons align as shown.
Note One thing to remember w hen aligning components is that the alig n
function uses units of points while the Align Distribute GUI uses units of
pixels. Neither method changes the
Units property of the components you
align, however.

menu to perform either operation immediately. For example, here are the six
options available from the Align menu item.
