Widget Event_Pro question [message #59480]

Hi guys,

As part of a little image display programme, I've currently got a draw
widget:

Display = WIDGET_DRAW(Base, XSIZE = S[0], YSIZE = S[1], $
/MOTION_EVENTS, EVENT_PRO = 'SLIDESHOWWIDGET_GETVALUES')

And I'd like to add button events to it. I don't want to get rid of
the motion events though. The easiest way that I can think of adding
functionality is to (ideally) have two Event_Pro strings, one to be
run if a motion event is detected, another if a mouse click is
detected. The two are going to do fairly different things here.
(If you're interested: the motion event will just update 3 labels
within the widget base to show x & y position and image intensity at
that point; whereas the click should start up a second, blocking
widget that's going to draw me a graph of image intensity change over
time at that point.)

Is there a way of doing this?
...perhaps by calling to widget_draw or even widget_control a second
time and defining a different Event_Pro? Can I even just superimpose a
second draw widget over the whole thing and give it its own event_pro?
I'd suspect that this latter approach would give it (my 2nd draw
widget) a different Window Index and mess things up royally at the
user interface :-(

Or am I just stuck making my SLIDESHOWWIDGET_GETVALUES programme big,
confusing and unwieldy?

Regards,
Chris
