Yes! The above code is missing a wart that is required to make it work:
1000 sleep
If I insert pause between each clause (set the slate action, request a
relayout) then this works. I've had to do this silly workaround in a few
programs. If you look in lsys, there's a 3 second pause.
I was meaning to bring this up to you at some point. So besides:
slate> relayout-1
Is there something I can call to force the ui to actually do the slate refresh
to effect the action call?
I reworked golden-section using a similar technique and it suffers from the
same problem; a 1 sec pause is necessary:
: golden-section-window* ( -- )
f <slate> { 600 600 } over set-slate-dim dup "Golden Section" open-window
[ gluNewQuadric >quadric ] closed-quot over set-slate-action
dup relayout-1
1000 sleep
[ display ] closed-quot over set-slate-action dup relayout-1 ;
