hello,
i was wondering if anyone could tell me what
arguments are being passed to the mysterious
DRAW method of the various IDLgr widgets.
I have created objects which inherit from
IDLgr things, and would like to be able to
perform calculations when the draw method is
called, then call the self->IDLgr<thing>::draw.
(i.e. i want to override the method).
so i have tried this, (and some other random
flails):
myobject::draw, _EXTRA=extra
but i get this:
% ARROW::DRAW: Incorrect number of arguments
(where ARROW is my own (special) arrow)
i read in the IDL manual that they have kept
many of the methods a secrete because things may
change in the future. so i assume that this
is one of those methods? should i not override
this one?
should i make myDraw, which you call prior to
the real draw?
any help would be apprecieted.
thanks,
don
