PhabChildren — a wrapper for the cdr function.
PhabChildren (widget_hierarchy)
The name of an instantiated widget hierarchy, as returned from a call to .PhabInstantiate, which is a method of the class created by PhabAttachWidgets.
This is a convenience function that provides a more meaningful name for the cdr function, when used in the context of a widget hierarchy. Since Gamma handles widget hierarchies as lists, the cdr of the list is a list that contains all of the children of the root widget. The children are actually each a single element of a list, so the return value becomes a list of lists, with each sub-list holding one child.
