MATLAB: Multiple callbacks to one callback

app designercallbackguivaluechanged

Hi, everyone,

I'm doing an app in the App designer and I got the following problem. I have some components and I need to do some process (always the same) when any of the components value changes. I would like to know if there is a way to put everything together in the same callback. This is something that will help me to avoid repetition of lines in the code.

I'm doing something like

ValueChanged callback in component one

Calculation ComponentOne.Value+ComponentTwo.Value

ValueChanged callback in component two

Calculation ComponentOne.Value+ComponentTwo.Value

What I would like to do is

ValueChanged callback in component one or two

Calculation ComponentOne.Value+ComponentTwo.Value

Thanks in advance

You can assign the same function as callback to multiple ui components.

Inside you function you will need to be able to access the properties under app directly.

function CommonValueChanged(app, event)
    app.ComponentOne.Value + app.ComponentTwo.Value
end

You can call the button pushed callback function programmatically, so if your callback looks like this,

 % Button pushed function: Button
 function ButtonPushed(app, event)
     % Do something       
 end

you can call it by the following.

ButtonPushed(app, matlab.ui.eventdata.ButtonPushedData)

callbacks are just functions. Call them using app.<callback name>. Just set the inputs correctly.

function NextButtonPushed(app, event)
    app.StationNo.Value = app.StationNo.Value + 1;
    % callback to the bleow function 
    app.PlotstationButtonPushed(app, event)
end
