DearPyGUI callback raises number arguments error

Python code using dearpygui that works in the interpreter, is raising a num arguments error for the Nuitka compiled version. Tested on Windows and Ubuntu with Python 3.9 and 3.10 with the same results - implying the issue is not related to Python version, c compiler, or OS.

I tried two versions of Nuitka, 0.7.7 and 0.8rc9,

$ python -m nuitka --version
0.7.7
Commercial: None
Python: 3.10.4 (main, Mar 31 2022, 08:41:55) [GCC 7.5.0]
Flavor: Anaconda Python
Executable: /home/martin/miniconda3/envs/dearpygui/bin/python
OS: Linux
Arch: x86_64
Distribution: Ubuntu (based on Debian) 20.04.4

$ python -m nuitka --version
0.8rc9
Commercial: None
Python: 3.10.4 (main, Mar 31 2022, 08:41:55) [GCC 7.5.0]
Flavor: Anaconda Python
Executable: /home/martin/miniconda3/envs/dearpygui/bin/python
OS: Linux
Arch: x86_64
Distribution: Ubuntu (based on Debian) 20.04.4

pip was used to install Nuitka.

dearpygui version is 1.5.1. Install: pip install dearpygui. dearpygui

Reproducible snippet,

import dearpygui.dearpygui as dpg

dpg.create_context()
dpg.create_viewport(height=200, width=200)
dpg.setup_dearpygui()

# works
def cb_button1(sender, app_data, user_data):
    print(f"sender: {sender} {app_data} {user_data}")


class myClass(object):

    def __init__(self):
        pass

    # throws num arguments error
    def cb_button2(self, sender, app_data, user_data):
        print(f"sender: {sender} {app_data} {user_data}")


myclass = myClass()

with dpg.window(label="Example", height=100, width=100):
    dpg.add_text("Hello world")
    dpg.add_button(tag="b1", label="Button1", callback=cb_button1)  
    dpg.add_button(tag="b2", label="Button2", callback=myclass.cb_button2)  


dpg.show_viewport()
dpg.start_dearpygui()
dpg.destroy_context()

Output of program,

$ ./nuitka_01.bin
sender: b1 None None
TypeError: myClass.cb_button2() takes 4 positional arguments but 5 were given

• Provide in your issue the Nuitka options used

python -m nuitka --standalone --onefile nuitka_01.py

The fix for this is in DPG, nothing Nuitka itself can do about it.

Well, or you could add a fake self argument to eat up the self they provide, but I understand there is an upstream patch in the works. Thanks for this, helps me a lot. I wouldn’t have the time to do it, glad you are taking it on.
