Force Mayavi to plot when figure embedded in a TraitsUI window about mayavi HOT 2 CLOSED

Found a hackish way to do it by looking at how mlab.show() works; this allows the code to function, at least on my system. Adding this before the mlab.screenshot() call causes the correct screenshot to be taken:

from pyface.api import GUI
_gui = GUI()
orig_val = _gui.busy
_gui.set_busy(busy=True)
_gui.set_busy(busy=orig_val)
_gui.process_events()

The _gui.process_events() was not enough (although this caused the image to go from black to light gray). I needed both that and _gui.set_busy(busy=True) to get it to work. Somehow this seems sub-optimal to me. Is there a cleaner way?

FWIW GUI().process_events() seems to be sufficient nowadays. I'll close as "resolved enough" :)
