QObject::startTimer: Timers can only be used with threads started with QThread

foggy cypress Jan 9, 2025, 7:45 PM

#

sudden scarab ```python class MainWindow(QMainWindow): def __init__(self): super()...

Something in your code is starting a QTimer. As QTimers depend on Qt's event loop, you'd preferably want to stay within Qt's ecosystem. So you'd want to use QThread rather than stdlib threads. Here are some decent resources if you want some general guidance on how to use them:

foggy cypress Jan 9, 2025, 7:47 PM

#

Sure, you're importing it. But the error complains about it being started. Are you starting a QTimer somewhere or do you have an idea of what could be?

sudden scarab Jan 9, 2025, 7:48 PM

#

it's gray, i mean QTimer is not being used anywhere in my code

foggy cypress Jan 9, 2025, 7:53 PM

#

sudden scarab it's gray, i mean QTimer is not being used anywhere in my code

Yeah, at least not in the code you've shared. Since I doubt Flask is starting a QTimer, can you share what the target function here is doing?

    hook_thread = threading.Thread(target=keyboard_hook, daemon=True).start()

sudden scarab Jan 9, 2025, 7:54 PM

#

def keyboard_hook():
    global script_active
    while True:
        if GetAsyncKeyState(ready_toggle_key):
            toggle_script()
            time.sleep(0.3)

foggy cypress Jan 9, 2025, 7:58 PM

#

Alright, GetAsyncKeyState seems to be a WinAPI function so probably not that. Maybe toggle_script and whatever that's calling?

#

!paste if you can share the entire code, that would work as well

wild nexusBOT Jan 9, 2025, 7:58 PM

#

Pasting large amounts of code

If your code is too long to fit in a codeblock in Discord, you can paste your code here:
https://paste.pythondiscord.com/

After pasting your code, save it by clicking the Paste! button in the bottom left, or by pressing CTRL + S. After doing that, you will be navigated to the new paste's page. Copy the URL and post it here so others can see it.

sudden scarab Jan 9, 2025, 7:59 PM

#

i can't, sorry

def toggle_script():
    global script_active
    script_active = not script_active

    if script_active:
        start_recoil_control()

    return "enabled" if script_active else "disabled"

#

in start_recoil_control all the same:

        if is_authenticated:
            while script_active:
                if GetAsyncKeyState(0x01) & 0x8000:

and it's can be called after authentication, problem in authentication so basically it's not starting and error is not here

#

hook_thread = threading.Thread(target=keyboard_hook, daemon=True).start()

removed and this error still appears

Are you able to at least share the part of the code starting the timer? I don't see anything in what you've shared that could possibly start one.

sudden scarab Jan 9, 2025, 8:11 PM

i have no any timers in my code gray means it's not used anywhere in my full code

error exactly here:

            w.show()

but idk how to fix it

#

sudden scarab error exactly here: ```python w = MainWindow() w.show() ...

Ah, I see what's happening.

You can't start a window like that since it's not within Qt's own event loop.
Since your route is effectively invoked by Flask using its own threads, Qt can't really start a window there since that needs to be done within the event loop.

There's probably workarounds for fixing this but I'll suggest just splitting the Flask code and the Qt code into separate modules then have your auth window send the requests to Flask and have Flask start a new process with your actual application.
-# There's also Qt Http Server as an alternative to Flask but, long-term, you'd still want to do these things separately.

eager adder Jan 9, 2025, 8:38 PM

Yeah my suggestion in python-discussion was to have them be separate processes too

eager adder Jan 9, 2025, 8:41 PM

So what exactly is the relationship between your gui and the flask server?

shit code but i think you see what i mean

eager adder Jan 9, 2025, 8:43 PM

#

Why do you need flask for this?

sudden scarab Jan 9, 2025, 8:43 PM

#

what can i use else?

eager adder Jan 9, 2025, 8:43 PM

#

Can you accomplish this with just a Qt gui?

sudden scarab Jan 9, 2025, 8:44 PM

#

i dont think that qss is better than css

#

im trying to make good gui

eager adder Jan 9, 2025, 8:45 PM

#

that's accessable via a web browser? If that's so then you don't need Qt - just use chrome or whatever browser you want

foggy cypress Jan 9, 2025, 8:45 PM

#

sudden scarab im trying to make good gui

I think they mean the stuff you're doing in Flask. You're already using Qt Web Engine anyways.

eager adder Jan 9, 2025, 8:46 PM

#

Yeah there's no reason to bring network communication protocols in to a completely localized gui

sudden scarab Jan 9, 2025, 8:46 PM

#

eager adder that's accessable via a web browser? If that's so then you don't need Qt - just...

no, it's a script for game not a website or smth

eager adder Jan 9, 2025, 8:47 PM

#

sudden scarab no, it's a script for game not a website or smth

That's what i'm saying. Then you don't need to use a webserver

#

Just implement your gui in Qt

sudden scarab Jan 9, 2025, 8:47 PM

#

sorry, my english is not so good. implement html and css in qt?

eager adder Jan 9, 2025, 8:48 PM

#

no. If you're not making a website, you don't need html and css to begin with

#

your gui can be done completely with Qt framework

sudden scarab Jan 9, 2025, 8:48 PM

#

yeah but it's already done on html&css

eager adder Jan 9, 2025, 8:49 PM

#

Ok. Then serve it up with flask and use chrome/safari/firefox/edge to view it. No qt needed then

sudden scarab Jan 9, 2025, 8:50 PM

#

this code is starting script in your pc, i can't do that

eager adder Jan 9, 2025, 8:51 PM

#

why not?

sudden scarab Jan 9, 2025, 8:51 PM

#

?

sudden scarab Jan 9, 2025, 8:51 PM

#

eager adder why not?

the same reason why your pc cant be turned off by clicking button on website?

#

or you mean starting flask locally

eager adder Jan 9, 2025, 8:55 PM

#

Ok just looking at the code you shared at the beginning here

#

So who is making the POST to your auth route?

sudden scarab Jan 9, 2025, 8:56 PM

#

sudden scarab or you mean starting flask locally

in this way it will work without qt, but other dev wants gui exactly in qt

sudden scarab Jan 9, 2025, 8:56 PM

#

eager adder So who is making the POST to your auth route?

js

eager adder Jan 9, 2025, 8:56 PM

#

sudden scarab js

from where

sudden scarab Jan 9, 2025, 8:57 PM

#

from web

eager adder Jan 9, 2025, 8:57 PM

#

from this?

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        self.setWindowTitle(' ')
        self.setGeometry(100, 100, 1050, 700)
        self.browser = QWebEngineView()
        self.browser.setHtml(html_content)
        self.setCentralWidget(self.browser)
        self.channel = QWebChannel()
        self.browser.page().setWebChannel(self.channel)
        self.channel.registerObject("bridge", self)

Does that html_content have the js that sends a POST to your auth route?

sudden scarab Jan 9, 2025, 8:57 PM

#

no it's other window

#

not auth

eager adder Jan 9, 2025, 8:58 PM

#

ok, but auth_content has the HTML that POST's to your auth route?

sudden scarab Jan 9, 2025, 8:58 PM

#

const response = await fetch('http://localhost:5000/auth', {

#

yes

eager adder Jan 9, 2025, 8:58 PM

#

ok

#

so you're trying to implement both a browser/client and a server in the same process

sudden scarab Jan 9, 2025, 8:59 PM

#

i did it before

#

yep

eager adder Jan 9, 2025, 8:59 PM

#

the flask server should actually serve that html content as another route

#

so you use a client process (like chrome for example) to go to http://localhost:5000/login or whatever you call it

#

that login route will serve the HTML

#

which contains the JS to POST to /auth

#

you don't need Qt to create a browser window

sudden scarab Jan 9, 2025, 9:00 PM

#

it's not my decision

sudden scarab Jan 9, 2025, 9:00 PM

#

sudden scarab in this way it will work without qt, but other dev wants gui exactly in qt

eager adder Jan 9, 2025, 9:01 PM

#

It seems like you're not actually giving him what he wants then. You're giving him a browser in Qt

why not anyway it works

eager adder Jan 9, 2025, 9:02 PM

#

sudden scarab in this way it will work without qt, but other dev wants gui exactly in qt

If this is what he wants, then you need to abandon Flask and HTML/CSS altogether

#

just do everything in qt

it can all be programmed directly

If Qt Widgets is not a requirement, consider QML or just using a standard web view.

eager adder Jan 9, 2025, 9:05 PM

You just have a window with a couple of text entries right?

sudden scarab Jan 9, 2025, 9:05 PM

i'm not doing that because i used qtwebbrowser

#

even forget about qt creator

30,000ft view of what you're trying to accomplish

#

what does that mean

sudden scarab Jan 9, 2025, 9:10 PM

#

macros for recoil control in game

eager adder Jan 9, 2025, 9:11 PM

Ok. And you're trying to create a Gui to configure it?

sudden scarab Jan 9, 2025, 9:12 PM

#

eager adder Ok. And you're trying to create a Gui to configure it?

it's already working im trying to implement second window(authentication) now

sudden scarab Jan 9, 2025, 9:16 PM

#

eager adder You can use the `subprocess`module to launch new processes

okay, for example separated code

flask
qt
even if i receive username, login in flask code, how would i use it in qt code?

eager adder Jan 9, 2025, 9:18 PM

#

I still don't think you need both. In my opinion, you should use one or the other

#

Either serve everything in flask and use a browser to view it, or create the entire gui in Qt

sudden scarab Jan 9, 2025, 9:19 PM

#

i have no time actually

#

to create a new one gui

eager adder Jan 9, 2025, 9:19 PM

it's okay

sudden scarab Jan 9, 2025, 9:20 PM

thats why
