Widget event question [message #1047]

I'm working on a widget application using IDL v3.0, and I would like to know
if there is any way for me to tell if, at any given time, there is another
widget event waiting to be processed.

Here's the scoop: In my rouinte, if the user causes certain events, the user
can change a plot. However, the plot may take a few seconds (or more) to
recreate, while the human has already clicked to cause another event. What
I'd like to do is have the routine _only_ redraw the plot when there are no
pending events, but I don't know how to determine if there are pending widget
events.

Has anyone done this sort of thing?

Thanks,
Joel
