Yes. Just create a PUBLIC property or a public function in your dialogue app and call it everytime you change something in your main app. You can use try catch block or a handle validation.
% In your dialogue app - "dialogApp.mlx"
properties (Access = public)
myProperty
end
methods (Access = public)
function myPublicFunction(app, newValue)
app.myProperty = newValue;
end
end
% In your main app
properties (Access = private)
hWin = [] % handle to your dialogue window
end
% Callback for a pushed button, opening your dialogue window, for example
app.hWin = dialogApp(app);
% Changing a value in your dialogue windows from your main app
if ~isempty(app.hWin)
app.hWin.myPublicFunction(10);
end
% Or...
try
app.hWin.myPublicFunction(10);
catch
end
% Or...
try
app.hWin.myProperty = 10;
catch
end
