Hello the community !
I come today with a new question about Matlab App Designer, and especially about the components creation.
Let's build a very simple app, composed of the button.

Using the graphical tool, the generated code is :
% Create DirebonjourButton
app.DirebonjourButton = uibutton(app.UIFigure, 'push');
app.DirebonjourButton.ButtonPushedFcn = createCallbackFcn(app, @DirebonjourButtonPushed, true);
app.DirebonjourButton.Position = [60 395 100 36];
app.DirebonjourButton.Text = 'Dire bonjour';
I copy all the code of the .mlapp file and paste it inside a new blank .m file.
Then, replace the autogenerated code below by :
% Create DirebonjourButton
app.DirebonjourButton = uibutton(app.UIFigure, 'push', 'ButtonPushedFcn', createCallbackFcn(app, @DirebonjourButtonPushed, true), 'Position', [60 395 100 36], 'Text', 'Dire bonjour');
Results in a lower code file, BUT do I get in terms of performance ? Or on the contrary is it worse ?
Waiting for your opinion (my app contains arround 200 components and takes more than 20 secondes to be ready after starting up !)
Thanks,
Robin
