1.8 Parents and Children

Each window and element has a single parent. A window's parent is either the display on which it appears or another window. An element's parent is a window. If P is the parent of C, then C is a child of P.

A is an ancestor of C and C is a descendant of A if

  1. A is the parent of C, or
  2. there exist one or more windows (B1 ... Bn) such that A is the parent of B1, Bn is the parent of C, and, for x equal to B1 through Bn-1, Bx is the parent of Bx+1.

A window or element inherits default values for certain attributes from its parent. A window or element cannot be created before its parent is created. A window or element can be created by the same M[UMPS] command that creates its parent.

P is a parent menu of S and S is a submenu of P if S is displayed when a choice in P is activated.
