kivy: firing multiple functions on 1 button click

Question

I have this code and it works, but I'm sure it's not the way to go properly. In my .kv a button fires two functions in my main.py.

    Button:
    text: "Press Me"
    on_release: root.on_our_btn_release(text_input.text)
    on_release: root.get_items(text_input.text)

Next step in my awesome project will be adding a lot more functions that will have to go off when the same button is clicked. This will result in a rather long list like:

    Button:
    text: "Press Me"
    on_release: root.on_our_btn_release(text_input.text)
    on_release: root.get_items(text_input.text)
    on_release: root.another_function(text_input.text)
    on_release: root.andanotherone(text_input.text)
    on_release: root.herewegoagain(text_input.text)
    on_release: root.this_is_getting_boring(text_input.text)
    on_release: root.think_you_got_the_picture(text_input.text)

This looks to me as very ugly code, but I didn't find a pretty way to do this yet.

Anyone? Thanks in advance!

You could structure this in a number of different ways, and the best option is mostly up to you.

One option if you don't want too many functions in kv is to call a single root.do_everything(), and put all the other calls in that on the python side.

Thank you for your reply. I already guessed (and found on Google) that there are numerous ways to fix this, but I like to learn what would be the most efficient way. – Erik van Elten May 12 '16 at 10:34

I believe a slightly more elegant solution would be to indent and list the different callbacks.

on_release:
    first()
    second()

Another possible but ugly solution for this can be to separate the functions with a semicolon.

on_release: first(); second()

You could make use of "on_press" and "on_release". Assign one method/function to "on_press" and the other to "on_release"

Could you share a code example on how to do it? – Simas Joneliunas Jul 13 '21 at 00:46
@SimasJoneliunas I believe they mean binding one function to `on_press` (ex. `on_press: first()`) and another one to `on_release` (ex. `on_release: second()`) – SomeMosa Jul 13 '21 at 01:42
yes I definitely meant what @Pokechu48 just stated – Derek Jul 15 '21 at 22:07
