<*PRAGMA LL*>A
RootVBT.T provides the up methods for VBTs at the root of
an applications, the methods that talk to an X server or talk
RPC to a parent VBT in another address space.
A RootVBT.Child provides a series of filters that are useful
at the root of applications.
INTERFACERootVBT ; IMPORT Filter, Split, VBT; TYPE T <: Split.T; Child <: Filter.T; PROCEDURE NewChild(ch: VBT.T; p: DeleteProc := NIL): Child;
Return a stack of filters overchthat implement et-agenting, highlighting, palette initialization on rescreening, and callsp(ch)before forwarding a deleted or disconnected code toch, ifp # NIL. In any case, after a deleted or disconnected code it removes the child from the filter.
TYPE DeleteProc = PROCEDURE(v: VBT.T) <* LL.sup = VBT.mu *>; PROCEDURE Misc(v: Child; READONLY cd: VBT.MiscRec);
= Child.misc. This will go away when the compiler bug is fixed.
