OffsetPopups.rex v01-00 07Jun12
The four dialogs in this file illustrate how popups can be tested in
stand-alone mode with a single code base. If a given popup pops up another
dialog, then this is treated as part of the "stand-alone" operation of the
first dialog.
Associated files: None.
Invocation: OffsetPopups [runType] [offset]
"runType" controls which dialog to surface in "standalone" mode as follows:
"p" for parent, "c" for child, or "g" for grandchild, "gg" for
greatgrandchild. Parent is the default (and of course "standalone mode" has
no meaning for the parent dialog, as when run it's always the root dialog.
"offset" is a number that governs the extent to which a descendant dialog
is visually offset from the ancestor that surfaced it.
The default is runtype = Parent and offset = 0.
