send parameters in button on_press

[alirezaimi]

Hi
Can i send parameters in button on_press event ?

self.button_relay1 = toga.Button(
    "Sw 1 OFF",
    on_press=self.sw_relay(1),
    style=Pack(padding=5, width=150, flex=1)
)

This example have this error :
06-16 13:41:02.202 3240 3240 E AndroidRuntime: com.chaquo.python.PyException: TypeError: 'coroutine' object is not callable

You can do it by defining the handler like this:

def sw_relay(self, button, *, my_param, **kwargs):
   ...

Then using it like this:

from functools import partial
self.button_relay1 = toga.Button(
    "Sw 1 OFF",
    on_press=partial(self.sw_relay, my_param=1),
    style=Pack(padding=5, width=150, flex=1)
)
