How to create a countdown timer on button face (maybe with Jgab's extra)

[Neo Andersson 142]

I am trying to update a button face of a QA every second for a certain given time.

I have tried it by using JGab's Fibaro extra's functions or just with simple settimeout but couldn't find a proper solution.

 

Question for Jgab:

Can't we somehow utilize Fibaroextra's Sequence function waiting part ? ex:

While the  60s is passing, let's every 1 sec update another button's label - self:updateView ("btn_1", "text", "running for "..x.." sec)

 

Or what can be the proper way to achieve this?

 

 

Thanks

Well, sometimes it can be an issue with the updateView refreshing the UI.

The sequence could be used but it's not necessary - as the real issue is to update the label every second.

and then call it like below. This way you could also  start multiple updates of different buttons in parallell...

Thanks, but i can't see where you define btn object?

btn.ref, btn.counter,btn.lbl and btn.fmt are created just by using them?

btn object doesn't need to be defined separately? In your example btn is an object containing properties ref,lbl,counter and fmt.

then when you call the sequence you just define an object btn1 with only two properties lbl and fmt ?

and it's important to define it once as both startButtonUpdate and stopButtonUpdate needs the same btn reference (counter and ref is stored there)

sorry for my bothering, but i still can't get, where you define forexample the btn.ref property?

it is used just inside the startUpdateButton function, so it will be lost outside of the function, am i right?

so when you refer to it in local stopUpdateButton(btn) if btn.ref then clearTimeout(btn.ref); btn.ref=nil end end then it is not storing any value, cause it is a local variable of startUpdateButton 

function.

Sorry, i must be really annoying..my wife is probably right

this is throwing error for me

Why do you change it to 'btn_start' and 'btn_stop' ?

it should be

that is declared on the previous line. Needs to be the same btn. Lua tables are passed by reference so stopUpdateButton and stopUpdateButton will get the same table and it's used to pass common values like .ref

okay, i changed it back, but the code still needs some brackets..I dont know what you meant by this part:

i mean, local loop() is supposed to be a function definition (and you just missed the function keyword) inside another function or it was supposed to be a variable definition??

i am totally confused

setTimeout(loop,1000)

Does that need some () ?

 

setTimeout(loop(),1000)
