[Discuss-gnuradio] Graphical sinks and visibility state

[Marcus D. Leech]

It looks like when a graphic sink isn't visible, it doesn't "run".

Is there a clean way to override this behaviour?

For some types of graphical outputs, like waterfall sinks, which show a
time series, having that waterfall
  stop, simply because it isn't currently visible, is broken.   If you
have said waterfall in a multi-tab
  "notebook" for example, and you're currently looking at another tab,
that waterfall won't run, and
  you can miss temporal trends in the data.  Is there an easy way to
turn that not-correct-in-many-cases
  behaviour off?
