Subject: AtPlotter: displayed resource doesn't realy work???
Date: Thu, 04 Apr 91 16:03:50 +1000
From: Gregory Bond <gnb@bby.oz.au>

I have spent the last day or so experimenting with the AtPlotter, and
I don't think the displayed contraint resource is being used for
anything.  The only place it gets looked at is in the SetValues
routine where it forces a redraw if it changes, but the redraw code
etc never seems to look at it.

Am I right?

The reason this is useful is that when using Wcl to prototype
applications, you can't add the data until after the widget is created
(you use the WcCallback resource to execute a callback to attatch the
data).  This means the widgets complain about zero size at creation
time.  What I intended to do was create the widgets with
displayed=false, attatch the data, then set displayed=true.  Displayed
is ignored so I cant do it....   Damn.

Greg.
