The ZSplitUtils
interface contains utility procedures for working
with ZSplit
s. The ZChildVBT
interface contains some additional
utility procedures that are oriented for children of ZSplit
s that
are used as subwindows.
INTERFACEReturn the lowest (possibly improper) ancestor ofZSplitUtils ; IMPORT VBT; PROCEDURE FindZChild (v: VBT.T): VBT.T;
v
whose parent
is a ZSplit.T
and which is not the ZSplit.T
's background child.
If no such VBT
is found, return NIL
. There's a good chance
that the VBT
returned is a ZChildVBT.T
, but this is not
required.
