Not correct.
Ok. I stand corrected. This is why it is done in #drawOn: and not
#drawSubmorphsOn:
Submorphs are only recreated when the view of the list has changed
#canRefreshValues, ie if the variable "needsRefreshExposedRows" is
set to true. If this is false nothing will happen in #drawOn:
If changes is necessary the drawOn: will recreate submorphs for the
current view (showIndex) and set the "needsRefreshedExposedRows" to
false signalling that it is correctly laid out.
What is interesting, still, is that submorphs rebuilding (deleting and
recreating them) happens during a #drawOn: call, and that it is fast
enough not to register on the time needed for a world redraw.
And so I still think it is interesting for Igor to have a look at FT :)
