Creating a box overlaid on an image to identify a subset of data for analysis [message #37599]

Dear users group,

What is the standard way of showing a box over an image in IDL? The
widget_draw routine allows for keywords "motion_events", and
"button_events". So the cursor positions may be obtained from the events
structure.

The intention of the application is to allow a mouse click press, drag and
then release to indicate a region of data that will be processed and
displayed in another window. With a combination of if statements checking
on the button state and over plots, I'm sure I could kluge something
together, but is there a standard routine or method to perform this task?
Thanks.

Regards,
