Breakpoints set in modules running in separate thread are ignored.

[FaceCrap]

It looks like PyScripter will only debug code in the main thread. Breakpoints set in modules which run in a separate thread are completely ignored.

Cannot reproduce here (see below). Which version of PyScripter are you using?
Could you please provide a minimal python script to replicate the issue.

As you can see here, there are two threads paused (stopped at a breakpoint). The main thread is running, but waiting for the other threads to finish.
You can inspect the call stack, variables etc of each paused thread.

When you press resume all paused threads will start again.

I'm running version 4.2.5.0

and a minimal script... I'm by far no python expert and I'm dealing with a GUI app built with PyQt6 which I didn't create myself.
I don't see how I can even begin to reduce this app to a minimum example and have it still working...

Please try with the preview of the next version.

I works here with the following script:

from PyQt6.QtCore import *
from PyQt6.QtWidgets import *
from requests import Session
from threading import Thread
from time import sleep

name = "John" #input("Please enter your name: ")
chat_url = "https://build-system.fman.io/chat"
server = Session()

# GUI:
app = QApplication([])
text_area = QPlainTextEdit()
message = QLineEdit()
layout = QVBoxLayout()
layout.addWidget(text_area)
layout.addWidget(message)
window = QWidget()
window.setLayout(layout)
window.show()

# Event handlers:
new_messages = []
def fetch_new_messages():
    while True:
        response = server.get(chat_url).text
        if response:
            new_messages.append(response)
        sleep(.5)

thread = Thread(target=fetch_new_messages, daemon=True)
thread.start()

def display_new_messages():
    while new_messages:
        text_area.appendPlainText(new_messages.pop(0))

def send_message():
    server.post(chat_url, {"name": name, "message": message.text()})
    message.clear()

# Signals:
message.returnPressed.connect(send_message)
timer = QTimer()
timer.timeout.connect(display_new_messages)
timer.start(1000)

app.exec()
