ok so now I go to the tasktrackercontroller

and under updateweight

I subscribe the message that is being sent

how do I subscribe to another file though?

I import it:
> from views import tasktrackerpanel

Ivo Flipse

@KronoS you can subscribe to anything/everything

messages go everywhere, your app shares one instance of pubsub

KronoS

and then pub.subscribe(????, "ButtonClass.toggeledbutton)

Ivo Flipse

well technically not even that, you just have one pubsub on your whole computer

KronoS

@IvoFlipse oh so I don't need to import

Ivo Flipse

???? = your function

well you need to import pubsub

from wx.lib.pubsub import Publisher as pub

which you already have

KronoS

10:06 PM

right

Ivo Flipse

so instead of that Weights class, I think we can suffice with just a simple function

KronoS

is a little bit lost

brb (gonna get some water)

ok back...

Ivo Flipse

ok, so what part is troubling you

KronoS

ok so I know that I need to send a message from tasktrackerpanel to tasktrackercontroller

I've created the message... now I don't know how to subscribe exactly

pub.subscribe('what','what')

AND how in the WORLD did you figure this all out in just a few short months

Ivo Flipse

@KronoS in university you learn whole topics in mere months, so I did the same only I just had one topic

KronoS

10:13 PM

oh I guess that's true

Ivo Flipse

anyway you pub.subscribe('message', function)

KronoS

Ah... ok so in this exact case it's

wait isn't it the other way...

function and then message?

pub.subscribe(self.store_result, "tasktrackerpanel.store_result")

cuz i saw this

Ivo Flipse

ah yeah, I did it the other way around

you are correct

KronoS

so this is what I need to do

in the init of the TaskTrackerController

and actually I'm changing the message to be 'tasktrackerpanel.toggeledbutton'

so it's easier to trace

Ivo Flipse

careful to subscribe functions that don't have (self, message) in their def statement

pubsub checks for these things and will give you an error if the function can't accept more arguments

KronoS

10:20 PM

ok... so now i have the two linked up...

Ivo Flipse

ok then what do you do

KronoS

ok just sent a push just in case something happened... (I also made some interface changes)

Ivo Flipse

pub.subscribe()

test = 0;

KronoS

@IvoFlipse well I'm guess that I need to do something with updateweight

Ivo Flipse

subscribing to () means you subscribe to everything == bad ;P

KronoS

10:31 PM

ignore that for now

I just deleted it anyways...

Ivo Flipse

in the init add:

self.weight

the in this function do

self.weight = message.data['state']

KronoS

@IvoFlipse 'this' meaning init?

Ivo Flipse

class TaskTrackerController(object):
    def __init__(self, app, model):
        self.app = app

KronoS

and I'm assuming that I need to do this after the subscription lines

right that's what I was talking about

Ivo Flipse

no, just initialize self.weight = 0

KronoS

10:33 PM

ok that's done

Ivo Flipse

btw

KronoS

@IvoFlipse wait what?

Ivo Flipse

add a line: assert self.weight >= 0 # check if self.weight isn't negative (for whatever reason)

@KronoS in the init, add that line

then in your function you change the value

KronoS

ok so I have in init:

> self.weight >= 0

then in updateweight:

I need what?

Ivo Flipse

self.weight = message.data['state']

KronoS

10:38 PM

ok... so why did I need to have the self.weight >= 0 in the init function?

Ivo Flipse

@KronoS oh weight its: self.weight += message.blabla

because you have to create the object somewhere, in the init means it exists as soon as the instance exists

KronoS

oh... ok

so in init i need self.weight += message.['state']

Ivo Flipse

no in the function

KronoS

so i leave self.weight >= 0

Ivo Flipse

paste your code in some google docs

and I'll tell you what to change

KronoS

10:44 PM

docs.google.com/document/d/…

KronoS

11:31 PM

I pushed the update @IvoFlipse
