Sorry to bother you again...
The keyword that controls the display attribute for the
graphics is controlled by a keyword "hide"
o->setproperty, hide=1
makes the object invisible :)
o->setproperty, hide=0
does not bring it back :(
Is there a way to bring my object back or did I lose
it for good?

mumble.. mumble...
sorry. I was a bad student at Davids course.
He told me not to use keyword_set to check if the
user has entered a keyword. But I forgot...
if keyword_set(hide) then o->setproperty, hide=hide
is obviously not the same as
if n_elements(hide) ne 0 then o->setproperty, hide=hide
Now "hide" works just as I thought it would.
Thank you for your trouble,

Setting HIDE to zero should have made your object visible again. But the
window will need to be redrawn before you can see the change.
