Sorry, I forgot what I was writing about. :-)

So, that program above gives me a window, and I want
to do something in the window. Maybe draw a rubberband
box around some data points to do a statistical
calculation of some kind.

When I click inside the plot, I can move the plot!
Hooray! But, I don't WANT to move the plot. :-(

Moreover, I don't get those events (motion events?)
in my event handler. How am I suppose to program with
these things? Or, am I?

Also, if I click *outside* the plot, the window
itself draws a rubberband box. How did it know
that's what I was thinking about!? VERY cool! :-)

Cheers,

David
