Alignment Command

Use the Alignment command from the Layout menu to access a submenu of commands that enable you to align selected groups of controls. For details, see "Alignment Controls", earlier in this chapter.

For details about aligning docking controls, see "Allowing Control Docking", earlier in this chapter and the JadeDockBar and JadeDockBase classes in Chapter 2 of the JADE Encyclopaedia of Classes.
