Getting inputs from App designer and saving them at a mat file or .mfile

I am currently using Tab Group in App designer, and there are several radio button and list boxes that i need the inputs to put into a struct, but i am unsure about how to go about it. Everything i do breaks the App. How do i grab the inputs from the UI via class object?

Hey... I made an app in R2021b showing how to keep the main info of selected buttongroup and listbox objects. You should use "Tag" property a lot! :)

Hope it's helpful.

app.myStruct = struct('Type', {}, 'ParentTag', {}, 'SelectedObjectText', {});

hObj = [];
for ii = 1:numel(app.Tab.Children)
    if ismember(app.Tab.Children(ii).Type, {'uibuttongroup' , 'uilistbox'})
        hObj = [hObj; app.Tab.Children(ii)];
    end
end

for ii = 1:numel(hObj)
    switch hObj(ii).Type
        case 'uibuttongroup'
            selected = hObj(ii).SelectedObject.Text;

        case 'uilistbox'
            selected = hObj(ii).Value;
    end
    app.myStruct(end+1) = struct('Type', hObj(ii).Type, ...
                                 'ParentTag', hObj(ii).Tag, ...)
                                 'SelectedObjectText', selected);
end

So you created a pushbutton for the struct ? I am trying to pull the class objects directly into an array. I have included the code and the app.

Sorry, I'm missing something... do you want to keep the answers to process the data later?! If so...

myStruct = strucr('Age', struct('Items', {'18-28', '29-39', '40-50', 'Selected', '18-28'}), ...
                  'Gender', struct('Items', {'Female', 'Male', 'Intersex'}, 'Selected', 'Male'), ...
                  'Language', struct('Items', {'One', 'Two'}, 'Selected', 'One'));

So... for every buttonpushed, you enable the button of the next tab, filling your struct.

You can use the property "Tag" for identify wich radiobuttons is selected and the index of the selected value for listbox.

[Nwasinachi]

I was saying that you have created the struct under a separate push button rather creating one in a the properties and then linking all the push buttons and list box to it

[Nwasinachi]

 properties (Access = public)
        field1='Age'; value1= {'18-28', '29-39', '40-50', '51-61', '62-72', '73-83'}; 
        field2='Gender'; value2 = {'Female', 'Male', 'Intersex', 'Non-conforming', 'Gender-fluid', 'Genderqueer', 'Transgender'};
        field3='Language'; value3={'One', 'Two', 'Three', 'Four', 'Polygot'};
        myStruct = struct(field1,value1,field2,value2,field3,value3)
    end

I made the change, but still getting an error, field 1 is unrecongized.

[Eric Delgado]

Ok. See app attached.

[Nwasinachi]

i have created an empty struct in the properties. i am assuming that was the change you made to the last code.

i guess my question now is would the struct be included in each buttons call back? that i need to save the information for?
