Folks,
I'm getting a late start on getting up to speed on
IDL 8. I have a couple of questions.
1. In the IDLDE, why are the tabs now on the *bottom*
of the windows and not the *top*!? Can I change the
position? I feel like I'm becoming dyslexic as I
switch between IDL 7.1 (to get some work done) and
IDL 8 (to welcome the future).
2. I thought I would learn about the NG by porting
some of my DG applications. But, yowzer! Most of the
applications I wanted to port use some kind of
interaction in the graphics window. For example,
draw a rubberband box, move a line, window and
threshold, things like that. I can't seem to find
any way to do those kinds of things and use the
new graphics. Am I missing something? Are the
new graphics strictly for display and not for
interaction?
3. I have noticed when I start Catalyst applications
up (and, remember, these are all IDL objects) that
sometimes they work, and sometimes they fail with
strange errors. I'm not sure what is happening with
this yet, but has anyone seen strangeness when working
with lots of IDL objects? (I did discover a real bug
in one program, but the others I have investigated
seem to disappear if I reset the session and compile
again. I know this sounds like programmer error, but
I have reasons to think not.)
Thanks.
Cheers,
David
