Jupyter plot close. about vedo HOT 5 CLOSED

@calugo
Hi Carlos! Thanks a lot for your interest and this great feedback!!
To be perfectly honest I'm not expert of jupiter (shame on me..) but you are absolutely right: this not handled properly, if someone wants to type-in commands in a python or jupiter session.
I could easily add a small function that closes the window.
Meanwhile this should work (python3):

import dolfin
from vtkplotter.dolfin import datadir, plot, Plotter

def closeWindow(pme=None):
	if not pme:
		from vtkplotter.settings import plotter_instance
		pme  = plotter_instance
		if not pme:
			return
	pme.window.Finalize()
	pme.interactor.TerminateApp()
	del pme.window
	del pme.interactor
	return pme

mesh = dolfin.Mesh(datadir+"dolfin_fine.xml")

pme = plot(mesh)
 
# now I press 'q' to exit the window interaction, 
# windows stays open but not reactive anymore

input('Control returns to terminal shell (press Enter)')

closeWindow()

# window should now close, the Plotter instance becomes invalid
# but mesh object still exist in it:

print(pme)
#pme.show() #this would cause error

# can create a brand new Plotter and show the old object
pme2 = Plotter(title='Second Plotter instance')
pme2.show(pme.actors[0].color('green'))

On the other hand one can go back to interaction by simply call

#.... non interactive script
plot()

Let me know if this works for you!

fantastic, I will add the new function in the next release.
I'm also thinking of adding the method interactive() to go back to the rendering window, which would be equivalent to plot() with no arguments... maybe that's more intuitive... (?)

Hi, well i think that this would be useful as often one likes to work along the image.

I think you commited the above function? Thanks a lot.

yes - it should be already available in the release,
