function ChangeColorButtonPushed(app.PushButton) %app.PushButton came from another function
    %cahnge background color
    app.PushButton.BackgroundColor = 'red';
end
%continue to callback function

so the question is How to pass the Push Button handles and use it inside the function?

I've tried this below inside the callback function but it didn't work...

ChangeColorButtonPushed(app.PushButton)

As long as your function has 'app' as a varargin you should be able to access your button handle.

For exemple if you want to know the coor of the button through a function:

colorbutton=ColorButtonPushed(app).

function result=ColorButtonPushed(app)

result= app.PushButton.BackgroundColor

end

In general, "app" should always be an input of your funcitons in app designer
