Experimented with implementing a progress bar for longer tasks in Modo, didn't quite get it to work due to focus being stolen from rendering.

modo_monitor_example.py

import lx
from time import sleep

SECONDS = 15

# Initialize the monitor object, ie progress bar.
monitor = lx.Monitor()
monitor.init(SECONDS)

# Mimic a long operation that users might want to stop.
for i in range(SECONDS):
    sleep(1)
    try:
        # If user aborts the monitor, a runtimeerror will be raised.
        monitor.step(1)
    except RuntimeError as error:
        lx.out("Operation cancelled by the user.")
        break
