Eightteen months ago, I wrote this fine group:
I have written a widget object which replaces much of the functionality of
the table widget but includes
- multiple rows of column labels
- different color backgrounds and foregrounds per cell
- different alignments per cell
- different fonts for the column labels and table body
- none of the weird sizing problems of the table widget
It uses a draw widget with separate pixmaps for each cell.
That's the good news. The bad news is that I wrote this object for my own
needs and so it is not really documented (yet).
I would be glad to give out the code as is, or if there is enough interest I
could make it available in a more easily usable form.
I got no takers then, and of course I never got around to documenting the
code, but the offer still stands.

Man, that's clever. (is the IEPA listening?)
Works like a champ for Windows.
UNIX didn't like it as written , but I think the technique will apply!
Thanks to David Burridge and Pavel for their kind input!!!
I LOVE workarounds and hacks like this. It sure beats just not being
able to do it :-)

Dave is right. Nobody here would ever think I'd recommend dumping IDL.
But many people would agree to the suggestion to dump Table widget :-( I
have never seen an elegant Widget_Table workaround.

I couldn't resist a a gross hack for this!-)
If you create an unmapped draw widget, you can call cursor with /nowait and
grab the mouse state from !Mouse. Not pretty, but it works ... kinda:-p I've
attached the test program at the foot of this post. You'll have to diddle
with it to respond to more than the first click on a table cell.
Suffice to say, I would *never* do this in a serious program, but you got my
interest piqued!!!
Cheers,
Dave

I assume that Pavel was referring to not using Table Widgets rather than
suggesting that you ditch either IDL or Motif?

Pavel -
I would beg to disagree! IDL and even the cranky Motif world are
AWESOME for satellite imagery. Nothing touches IDL for doing image
processing on our giant pixel counts. After a fashion I even like the
widget programming setup in IDL. It's more than worth it to get the
sweet
IDL functionality into our apps, instead of trying to ape this stuff
in C or another language.
My thanks to this group, whose collective tutelage and wisdom has
allowed me to
begin scratching the surface of this power.( And esp. to Dr Fanning
for
IDL Programming Techniques vol2., not to mention Ronn Kling's
Application book,
great stuff, that.)
So, for my RSI wish list 2003, add a field to the CellSelection Event
for clicked:[0,1,2]
Thanks!

From all I heard here so far, some other interface would be much
prefered by satellite image community. Table widgets (unless they
changed drastically in 5.6) were pretty non-intuitive and (in my
experience) did not look the same across platforms.
Regarding the original question - correct me if I'm wrong, but draw
widgets I think are the only ones that distinguish between left, mid and
right mouse clicks. It would be nice if they added Shift and Alt
clicks... I wouldn't have any other user inputs in my programs, then :-)
Cheers,
Pavel
