MATLAB: Changing the value of a spinner from another spinner

spinner

Hello all,

I have 2 spinners in my app, spinner1 and spinner2, and I want to change the value of spinner 2 while I am changing the value of spinner1. I have tried several things without luck. The following code describes what I am trying to do.

function spinner1ValueChanging(app, event)
     changingValue = event.Value;
     app.spinner2ValueChanging(app, event);      
end

Thanks for your help!!

I'll just put it here for future reference :)

Like most other objects, the slider is adjusted by changing the value field

app.spinner2.Value = changingValue

I managed to solve the issue. Here is the code for it.

% Value changed function: Spinner
        function SpinnerValueChanged(app, event)
              previousValue = event.PreviousValue;          
              app.Spinner.Value = (app.Spinner.Value + (app.Spinner.Value - previousValue));
              value = app.Spinner.Value;
            if value > 0
               app.Spinner.Value = -2;
            elseif value < -2
               app.Spinner.Value = -0;
            end                      
        end
        % Value changing function: Spinner
        function SpinnerValueChanging(app, event)
            changingValue = event.Value;
            if changingValue > 0
                app.Spinner.Value = -2;
            elseif  changingValue < -2
                app.Spinner.Value = 0; 
            end        
        end
        % Selection changed function: ButtonGroup
        function ButtonGroupSelectionChanged(app, event)
           if app.mVButton.Value == 1
              app.Spinner.Step = 0.0005; %needed to divide by 2


           elseif app.mVButton_2.Value == 1
              app.Spinner.Step = 0.005; %needed to divide by 2
           else            
              app.Spinner.Step = 0.05; %needed to divide by 2
           end            
        end
        end

I beleive your error is here

% Code that executes after component creation
        function startupFcn(app, MainApp, a, b, c)
            % Store main app in property for CloseRequestFcn to use
            app.CallingApp = mainApp;    % <----------------------------- HERE

Should be

            app.CallingApp = MainApp;   % with capital M

Make that change, save the app, close the app, restart it, and test it. If the problem persists, I'd be glad to look further.
