Well, OK. You get the event in one of your windows.
You move the image in that window. What is preventing
you from also moving the images in the other two windows
at the same time?
Cheers,

Hy David!
I'm sorry, but I couldn't get the idea.
I've built 3 widget_bases with WIDGET_DRAW on them, and I load images
from the same area, but diferent points in time into them. My idea is
to link these images, so that when I move one image, the other 2 would
automatically move. The images are bigger than the window. That's why
I want to link them. We can do that in a very easy way with ENVI.
I keep my images in an info.
I want to draw in any of the 3 windows
thank you..

There is no code for this. But it is nothing more than
Programming Logic 101. There are only three things to
keep in mind: (1) Where is your data (in an info or
state structure, probably)?, (2) Which window do you
want to draw into (probably also in your info structure)?,
and (3) What do you want to do in this window?
It's really pretty simple.
Cheers,
David
