I am creating a GUI in the app designer, and i have several list box and push button, they are all running based of call backs.
My questions are;
How do you save the inputs from the list boxes and push buttons.
How do create an array that save the information of each user without replacing the previous one
How do you link all the apps so that the infomration from each app is saved in the array

Maybe it is easier to combine the set of GUIs into one GUI with different tabs.
It is not clear, what "record responses" mean. If you click on a GUI element, its value changes automatically. So afterwards you can request the property "Value".
Until now you have explained the purpose of the code by text only. Then an explicit suggestion for a modification of the code is not possible. Answering would be much easier, if you post the relevant part of the code.

"Maybe it is easier to combine the set of GUIs into one GUI with different tabs". How can this be achieved? i have tried including the 2nd GUI into the input argument and that didnt seem to work.
I guess what i want is to be able to have the property value for each GUI update into a matrix i will create.
i have included the code.
classdef Age < matlab.apps.AppBase
% Properties that correspond to app components
properties (Access = public)
UIFigure matlab.ui.Figure
ListBox matlab.ui.control.ListBox
ListBoxLabel matlab.ui.control.Label
NEXTButton matlab.ui.control.Button
TextArea matlab.ui.control.TextArea
TextAreaLabel matlab.ui.control.Label
end
% Callbacks that handle component events
methods (Access = private)
% Code that executes after component creation
function startupFcn(app)
end
% Value changed function: ListBox
function ListBoxValueChanged(app, event)
value = app.ListBox.Value;
if strcmp(app.ListBox.Value ,'18-28')||strcmp(app.ListBox.Value ,'29-39')||strcmp(app.ListBox.Value,'40-50')||strcmp(app.ListBox.Value,'51-61')...
||strcmp(app.ListBox.Value,'62-72');
set(app.NEXTButton,'Enable','on');
end
end

Hi @Nwasinachi
You can use a ‘TabGroup’ and reposition the ‘TabGroup’ such that the tab menu bar is out of visual boundary. Like in the following image:
Note: I have not completely hidden the TabGroup just to show you the idea.
If your app is resizable then you must dynamically adjust the position of TabGroup in resize callback of window.
If it is a fixed resolution, then you can fix everything to achieve the above shown layout.
You can use the callback of ‘Next’ and ‘Back’ to switch between tabs.
Hope this helps!

Awesome this helped alot, but the problems seems to be that i am unable to use more than one call back function for the push buttons.
app.TabGroup.SelectedTab = app.AgeTab this seems to be the one working, the one for Gender dosent work at all.
% Callbacks that handle component events
methods (Access = private)
% Callback function: NEXTButton, NEXTButton_4, WelcomeTab
function ButtonPushed(app, event)
app.TabGroup.SelectedTab = app.GenderTab
app.TabGroup.SelectedTab = app.AgeTab
end
% Value changed function: ListBox, ListBox_3, ListBox_4
function ListBoxValueChanged(app, event)
value = app.ListBox.Value;
if strcmp(app.ListBox.Value ,'18-28')||strcmp(app.ListBox.Value ,'29-39')||strcmp(app.ListBox.Value,'40-50')||strcmp(app.ListBox.Value,'51-61')...
||strcmp(app.ListBox.Value,'62-72');
set(app.NEXTButton,'Enable','on');
end
value = app.ListBox.Value;
if strcmp(app.ListBox.Value,'Female')|| strcmp(app.ListBox.Value,'Male')||strcmp(app.ListBox.Value,'Intersex')||strcmp(app.ListBox.Value,'Non-conforming')...
||strcmp(app.ListBox.Value,'Gender-fluid')||strcmp(app.ListBox.Value,'Genderqueer')||strcmp(app.ListBox.Value,'Transgender');
set(app.NEXTButton,'Enable','on');
end % simple loop that allows the push button to stay unable until the person selects an option.
value = app.ListBox.Value;
if strcmp(app.ListBox.Value ,'One')|| strcmp(app.ListBox.Value ,'Two')|| strcmp(app.ListBox.Value ,'Three')...
|| strcmp(app.ListBox.Value ,'Four')|| strcmp(app.ListBox.Value ,'Polygot');
set(app.NEXTButton,'Enable','on');
end
