calico.display() not working inside event handlers

[Keith O'Hara]

calico.display() not working inside event handlers.

from Processing import *
window(500, 500)
def g():
    calico.display("test") 
onMouseDragged += g
loop()

This doesn't work for me either:

from Processing import *
window(500, 500)
def g():
    print("test") 
onMouseDragged += g
loop()

This looks to be a problem with the Processing library, yes?

[Doug Blank]

This works:

from Processing import *
window(500, 500)
def g():
    global x
    x += 1 
onMouseDragged += g
loop()

and x increases.

The output redirection is broken in icalico.

Everything else besides Processing seems to work.

Output in other threads don't seem to make it to the output. This works:

import threading
import datetime
import time

class ThreadClass(threading.Thread):
    def run(self):
        x = 1
        while True:
            print(x)
            x += 1
            time.sleep(1)

t = ThreadClass()
t.start()
t.join()

But remove the t.join() and it doesn't output.

I don't think IPython was designed to work this way. Trying some examples in regular IPython, it works similarly to how it works in ICalico (actually ICalico works a bit better). I think when the execution is complete, it stops listening for additional data coming in.

In IPython you can get the printout if you:

while True:
    pass

and then interrupt, you see output. In ICalico, you'll see the data without having to interrupt.

This is on hold until IPython changes their API. Actually, when they do, it will probably just start working.
