name error : self._target(*self._args, **self._kwargs)
TypeError: Alarm.dialog_alarm() missing 1 required positional argument: 'e',,,
idk how i fix this ! , I need Your HELP ....

Your method has 2 parameters:

• self
• e: ControlEvent

def dialog_alarm(self,e:ControlEvent):

But you're only passing one:

• e: ControlEvent

To fix this you need to pass self too

text_add_alarm = TextButton(
       text="Click to add new alarm",
       on_click=self.dialog_alarm,
)
