graphCanvas    IsA    Canvas   IsAn     ArchivedGeometryWidget

ArchivedGeometryWidget implements setSaveSizeFlag: (BOOL) flag

But    [graphCanvas setSaveSizeFlag: YES];
gives me a   "    'setSaveSizeFlag:' not implemented by protocol  "
I notice that it is in tkobjc/ArchivedGeometryWidget.h, but not in gui.h

If I don't use the GUI_UPDATE_IDLE_TASKS there, I get a blank
canvas with no graph and with my bugs all in a wiggly heap in the
extreme northwest corner.

Yes, that's where I knew I could use registerAndLoad.  I need that part
of the createEnd, but the rest of the super createEnd generates this error:

warm201/lib -Wl,--rpath -Wl,/swarm201/lib
//e/lab/geograph $ geo
(Tcl -eval:) window name "w40477592" already exists in parent
    while executing
"canvas .w40473384.w40477592"
while evaluating: canvas .w40473384.w40477592

When I call only the -registerAndLoad instead of the super's full createEnd,
it runs perfectly without any error messages.

I have a Canvas with Nodes, Links, and Circles running around on it,
so perhaps I am running into unusual GUI combinations for Swarm?

thanks!
