PySimpleGui throwing error when i try to login my bot-CodePudding

I am writing a bot manager for an app and I keep getting this error, I am not using the threading lib nor a Worker thread:

    log_msg = self.ui_element.get()
  File "C:\Users\derri\AppData\Local\Programs\Python\Python38\lib\site-packages\PySimpleGUI\PySimpleGUI.py", line 3515, in get
    value = str(self.TKText.get(1.0, tk.END))
  File "C:\Users\derri\AppData\Local\Programs\Python\Python38\lib\tkinter\__init__.py", line 3706, in get
    return self.tk.call(self._w, 'get', index1, index2)
RuntimeError: main thread is not in main loop`

The function:

    def emit(self, record):
        # Get the current logs
        log_msg = self.ui_element.get()

        # Format the log record and append
        log_msg  = self.format(record)
        print(record)

        # Update the UI element with the log message
        self.ui_element.update(log_msg)

ui_handler = UiLogHandler(window["logs"])
logging.getLogger().addHandler(ui_handler)

CodePudding user response：

Method emit called not in the main loop or main thread, so don't update GUI element in this method, replace it by method Window.write_event_value to generate an event to update your GUI element in your event loop, like

    def emit(self, record):
        # Get the current logs
        log_msg = self.ui_element.get()

        # Format the log record and append
        log_msg  = self.format(record)
        print(record)

        # Update the UI element with the log message
        self.window.write_event_value('Update', log_msg)

and in your event loop

    if event == 'Update':
        log_msg = values[event]
        ui_element.update(log_msg)
