Apps Add a custom value to ac.addOnClickedListener(identifier, callback)

[merradaberra]

Hello,

I was wondering if its possible to pass a variable to the callback function of the OnClickedListener. I have an array with buttons and they all need to do something else based on a value I have when setting the listener.

right now the x and y are passed to the callback function.

ac.addOnClickedListener(buttons[carId],btnClickEvent)

def btnClickEvent(x,y):
ac.console(str(carId))

But I would like to add a 3th parameter:

def btnClickEvent(x,y,carId):

Is there any way to do this?

instead of the function itself you can stick a lambda around it, like listener(buttons, lambda x,y: btnclickevent(x,y,carid)). It's just short way of writing a new function without bothering naming it etc.

He Stereo, thanks for the suggestion but that doesnt work. It seems that the name of the callback function of btnclickevent() is passed to c++. C++ then tries to find the function with pyObject_call in ac\control.cpp. Or so it seems. So a lambda doesnt work

Ah, right. looked up how I actually did it:

import functools

        fpar = functools.partial(onClassRank, class_name=item)
        fpar.__name__ = 'onClassRank'

def onClassRank(*args,class_name):

stereo did here too: https://www.racedepartment.com/downloads/carsel.9725/

import functools

    ...
    act = functools.partial(onButtonClick, driver=d)
    ac.addOnClickedListener(button,act)
    ...

def onButtonClick(*args,driver=0):
  ac.focusCar(driver)
