It would be nice if I could drag an image file from Windows explorer
and drop it into a Draw Widget and have it display automatically.
I've looked around a bit and doubt this is possible, but thought I'd
ask first before I gave up on the idea. Can IDL capture the name of a
file dropped into a display window?
Thanks,
Steve Hartmann

Uh, right. But don't let that stop you from
posting more articles. :-)

P.S. Let's just say hitting that Send button
has been know to result in great insight into IDL
programming. (In addition to great humility, of
course, but that goes without saying. We all wish
the cause and effect was the other way around, but
alas, it ain't so.)

Oh, I agree, these things always *sound* promising.
ION and Active X components via the IDL draw widget
sounded promising, too. But in practice, alas, they
are often less promising than one would have hoped.
But, then again, some of us are eternal optimists. :-)

Well then I'm glad you say it can't be done. My experience with this
newsgroup the last several years is that whenever you (dwf) say
something can't be done, it often gets done by one of the other stars.
Often, as in this case, that works out great for me. As I can always
(and do) browse for an image file, it would be neat to just drag and
drop into a window.
Thanks again,
Steve

I'm impressed.
There aren't many good windows programmers who are regular posters, so
it's good to see one chime in.
David was right, there isn't a way to do it in IDL. The solution isn't
really an IDL solution at all, but subclasses ... er, excuse me,
politely hijacks ... the IDL Widget window on an OS level (it's polite
because it gives the window back). I had to spend a little quality time
with my Big Thick Windows Programming(tm) book to figure out what was
going on.
Thanks for the solution and the interesting code!
Back to what I should be doing.
Best,
Rich

Very nice! It works on my Win2k machine as well. Thanks alot - I think
this will be very handy. I'm glad I re-posted the question.
I knew that someone on this group *could* do this, and I'm greatful
that you actually *did* do it.
Thanks,
-Steve

Duty calls.
In a renewed attempt to maintain my reputation of d.o.d.c, I hereby
post my nomination for "daddy's job of the year". Personally, I
think it makes J.D.'s text-widget subterfuge (of a couple of years
back) look as much a part of IDL as, say, a piston looks like a part
of an internal combustion engine. I'm particularly proud of my
method of getting "HWND"s for IDL widgets and challenge anyone to beat
it on the grounds of "ultra-risky platform-specific code that's sure
to break one day".
Anyway, it works. Or to be precise, it worked today on my PC running
IDL 5.4 on WinNT4 SP 6.
It can be had via anonymous FTP:
Server: ftp.syd.dem.csiro.au
File: dropfile.zip
You won't be able to get a directory listing of this server. If you
want a copy of this thing and the FTP doesn't work for you then email
me and I'll send it to you.

I'm glad that you found it useful. It's sort-of cringeworthy,
though, isn't it?
Once again I under-estimated the power of the "send" button and
yesterday, after posting, I began to worry about how hard-coded
"dropfile" is. I have since opened it up a bit so that it can be
used on something more complicated than the simplest base+draw_widget
program. The update's on "my" FTP server.
My apologies to those who tried to access the FTP server and couldn't
- I think there's still some kind of security block on the thing. It
would probably be best to email me if you want the program.
Cheers
