I think perhaps your code is taking advantage of a quirk in LC. If you
don't give an object a name, the childcontrolnames returns something like
this:
graphic id 1011
If that is in a variable tObject, then a statement like this will work:
delete tObject
But if you name an object, say "bob", then the childcontrolnames will
simply return "bob" and the delete will fail with a bad reference.
This works:
on test
drawLine 10,10,(50+random(50)),(50+random(50)),"red"
wait 2 seconds
deleteChart
end test
on drawLine x,y,x1,y1,tColor
lock screen
create grc in me
put the long id of the last grc of me into tID
set the style of tID to polygon
set the foregroundColor of tID to tColor
set the points of tID to x,y & cr & x1,y1
unlock screen
end drawLine
on deleteChart
lock screen
repeat for each line tID in the childControlIDs of me
delete control id tID of me
end repeat
unlock screen
end deleteChart
