Now, I am trying to make widget program that contains two plot with a
image. I also would like to include mouse-oriented indication bar in
both plot area, which synchronise with the position of the image. I
guess it would be based on something like XSTRETCH.pro from D.Fanning.
Question are, if I put those plots and image in a simgle Widget_Draw,
would it become much slower while interactive moving lines on plots
are moving? I wonder this is one of reason why XSTRETCH.pro has two
windows, i.e. two TLB.
In fact, since I tend to include loop that scans through the data
range, approximately 5000 steps within 1 or 2 minutes, speed really
matters to me. XSTRETCH continuously uses PIXMAP while moving lines
with mouse, and I guess such processing is possibly slower in, for
instance, 800-by-800 Widget_Draw.
Alternatively, I thought three different Widget_Draws in a single TLB.
Problem again comes when resize windows. Also, I am not sure how much
difference in processing speed with comparison to the pervious method,
and which method would be less complicate and more economical in
programming-wise.
If anybody faced such problem, I should be appreciate.

P.S. Thank you for your quick comment on SELECTIMAGE, Dave. Yes. It
looks great.
