vport id from user

All,

What's the best way to retrieve a viewport Id from a user. How can it
be picked and the id sent back to LISP.

For example, I can set the active viewport, but how does one ask the
user to select one? is the viewport is not the active one when the user
clicks it, then they need to click twice, once to make it active, and
once to satisfy the getXXXX request. I suppose I could use a dummy
value to get around the double vs single click responses.

Can the act of activating the viewport be captured some how.

I'm trying to assemble a list of viewports based on user clicks.

TIA

Bob:
I'd say to let them just pick a point inside the boundary of a viewport from
PSpace. You build a function that calculates what viewport(s) surround the pick
point. Or, use (entsel). But the former can work even if the viewport's layer
is frozen (which I still find that long-time users do).
