Some controls often appear together in applications. For example a float slider often has a field beside it to indicate its value, or an editable field often has non-editable text beside it indicating the nature of the field. Groups in ELF are collections of controls that are bundled together within one command for convenience. Using groups is more efficient and they also take advantage of ELF’s higher level formatting functions that will be described later. Anything that a group command creates can be created using the individual commands of its component elements. All commands that create groups end in “Grp”; for example, “floatFieldGrp”.
