Adding elements to list

[heyo]

I'm faced with problem when I add elements to list. For better understanding I explain what I want to do. So here when I click add new elements I go to other screen where config pinout. And when I click save it stores names like "VM1", "Main module" in array there is placed in model.hpp. In list layout I can create 5 elements.When I add more than 3 elements to the list my names somehow which I store in array disappear and random values which is in my project enrolls

What can cause this problem?

Hello @heyo​,

That looks like an out-of-bound issue.

How did you create and initialize your array ?

[heyo]

I create structure in model.hpp

This is how put information in to arrays

Can you also show me how you display your Array values into the screen ?

Also, why are you using 2-dimensionnal arrays for Headlines and Correction ?

@Yoann 2-dimensionnal arrays because in one row writes more than one symbol. I mean if I want to write "176" number I need three positions if I correctly understand.

AirTemperature_Save is how many times was pressed save I mean how many elements are in list. From the model.hpp I take data

Here adding elements to list :

And this is how create list members:

That's gonna be hard to debug without having access to your project, can you share it ?

Hi,

May I ask what is this line supposed to do ?

memset ( & Cfg_C7_temperature.Headline[idx][30] , 0, 30 );

If intention is to clear the string at index 'idx' then this is correct statement

memset ( Cfg_C7_temperature.Headline[idx] , 0, sizeof (Unicode::UnicodeChar)*30 );

Nope, this is not working for me as you said.
