At that point resizing the windows hangs the system comletely

@doutriaux1 I am hitting a similar problem with vcs plots and x.interact() preventing me from being able to close the opened canvas.. The only path forward is to kill the active ipython session - this is bad

[doutriaux1]

@durack1 if you have x.interact() you then need to hit Q while the windo is active to keep going. Are you doing this?

[durack1]

@doutriaux1 yep, hitting 'Q' returns the focus back to the console, but the canvas becomes unusable.. It responds to an x.clear(), but cannot be closed.. It becomes a zombie canvas.. It won't even close when hitting the window 'X' too..

[doutriaux1]

let's take a look next week

[durack1]

@doutriaux1 this was the issue we were discussing, however, it's vcs not dv3d that is having the issue, I have renamed the issue to reflect this

[durack1]

@doutriaux1 @danlipsa @aashish24 just fyi, this bug is preventing me from using vcs in interactive data discovery.. Which is really unfortunate, as I would prefer to use it.. Matplotlib on the other hand can successfully open and close interactive plotting windows, so I'm forced to use that instead

[danlipsa]

@durack1 Can you provide us the steps to reproduce the problem? I tried what Sam wrote but I cannot reproduce the problem.

[durack1]

@danlipsa I haven't checked this in a v2.10 ipython console (importantly it has to be a non-nox version), but this is what didn't work for me last time:

import vcs
import numpy

mat = np.zeros([5,5])
x = vcs.init()
y = vcs.init()
x.meshfill(mat)
y.meshfill(mat)
x.clear()
y.clear()
x.close() ; # This leads to a zombie window that doesn't die until the ipython session is killed
y.close() ; # Same here

[danlipsa]

@durack1 @doutriaux1 With 2.10 I get

>>> x.meshfill(mat)
Traceback (most recent call last):

@danlipsa try this:

[durack1]

@doutriaux1 is cdat_info.version() - > ['', '2.8.10'] right? I thought the latest release should be v2.10.0 instead..?

[doutriaux1]

@durack1 nice catch I'll patch this, right away.
