Thanks Joel, it did. (And thanks to the others who replied too.)
Here's a working (at least for me) version of the layout examiner...
---8<---
REBOL []
examine-lo: func [face][
style: func [face][
if error? try [return join " Style: " face/style][""]
]
examine: function [face spaces][panes][
prin join spaces type? :face
if not object? :face [print "" exit]
print style :face
append spaces " "
panes: get in face 'pane
print rejoin [spaces type? :panes style :panes]
either block? :panes [
foreach pane face/pane [examine :pane spaces]
][
examine :panes spaces
]
remove/part spaces 4
]
examine face ""
]
lo: layout [text-list]
examine-lo lo
---8<---
The example at the end there prints out...
object Style: none
block
object Style: text-list
object Style: none
object Style: none
block
object Style: box
function
function
object Style: slider
object
object
none
none
