I checked the Mac, and it behaves correctly, like Windows. It's only
Linux that doesn't, and I don't know why.<br>
<br>
I think you're right that the thing to do is to expose the same method
that is driven by clicking on the close box. I might not get to this
very soon, as I'm swamped getting out the third edition of a physics
textbook on a tight deadline.<br>
<br>
I don't know enough about GTK widgets to be able to comment on whether
your suggestion about widgets is feasible.<br>

I find that on Windows this does work properly running from a command
line. The C++ code does intend to exit the program if we reach the end
of the program and there are no windows visible. However, for some
reason exit doesn't happen on Ubuntu Linux. I didn't yet try on the Mac.

because in the shell window you can still execute statements, such as
scene.visible = True, so you're not really at the end of the program.
Clearly we need some statement that unequivocally kills the program.

I need to exit programmatically from the visual and close the window.
I'm using visual together with another main GUI window, so when I
close the main also visual should close properly.
When I click on the x in the right corner of the window the program
closes in a proper way, so why we don't expose the same method to the
python interface?

I think the method attached with the on_quit_clicked() (line 240)
should do the work.. we can give it a try.
On a side note making visual a GtkWidget Visual window would give much
more control, a nice integration within the gtk main loop, and more
sane event handling.
Do you think it is a good idea?

Michele

<pre wrap="">Hello list,
I'm trying to figure out how to close visual from the code and not
from the GUI, 'cause I need this feature.
Consider the following code:
import visual
import time
scene = visual.display()
cyl = visual.cylinder()
time.sleep(3)
scene.visible = False
if you run it with
python test.py
the command line keeps to be busy and the prompt never show up.
This does not happen if I click on the x on top of the gui.
I'm missing some bit?
Regards,
Michele.
