3 months ago Hello,
As is common with GUI frameworks, the GUI needs to be in the main thread. I would advise you to use two separate threads, with asyncio in a separate thread.
Example:
import asyncio
import threading
from imgui_bundle import imgui, immapp, hello_imgui
#
# GUI code
#
def gui() -> None:
imgui.text("Hello world")
if imgui.button("Click me"):
print("Button clicked")
def run_gui() -> None:
runner_params = hello_imgui.RunnerParams()
runner_params.callbacks.show_gui = gui
immapp.run(runner_params)
#
# Asyncio code
#
async def other_async_task():
while True:
print("Async task running...")
await asyncio.sleep(1)
def run_asyncio_loop():
asyncio.run(other_async_task())
if __name__ == "__main__":
# Start the asyncio loop in a separate thread
asyncio_thread = threading.Thread(target=run_asyncio_loop)
asyncio_thread.daemon = True # Make sure it exits when the main program exits
asyncio_thread.start()
# Run the GUI on the main thread
run_gui()

As in the title, I want to make use of imgui_bundle in python with an asyncio app. There is one way to do it using two seperate threads, but I don't fully comprehend what the consequences of that will be going further with the app.
I would like to try and run it together with asyncio in one thread if possible. If it is not, or it is a bad idea, then I will try the threaded approach.
Thanks in advance for the help.
