Update Element with Thread

I’ve this little examples that does not work… It’ doesn’t update the screen until I press a key.

Basically what I want is to run a thread that updates some element and update the screen Can you help me to understand why it is not completely working?

#!/usr/bin/env python3

import py_cui
import threading
import time
from datetime import datetime


class App:
    def __init__(self, master):
        self.master = master
        self.g1 = self.master.add_scroll_menu('PANEL',
                                              0, 0, row_span=6, column_span=6)
        thread = threading.Thread(target=self.thread_update, args=())
        thread.daemon = True
        thread.start()

    def thread_update(self):
        try:
            while True:
                d = "TIME:{}".format(datetime.now().strftime('%X'))
                self.g1.add_item(d)
                time.sleep(1)
        except Exception as e:
            print(e)


root = py_cui.PyCUI(9,6)
root.toggle_unicode_borders()
root.set_title('Test')
s = App(root)
root.start()

Is it a thread/curses limitation?

Yeah, for sure some of the documentation (like for this) needs to be overhauled eventually, I’ve just been busy with work lately, hopefully I have some extra free time in the coming months to dedicate to this.

Great! The new version will be uploaded on PyPi in the next few weeks with the fixes.
