I have tried copying the Settings *settings to a class variable and using
sets->setTitle("new title");
but outside the setup() method it doesn't work. Is there a workaround to that?
Everywhere in your app where you include the cinder app header
#include "cinder/app/AppNative.h"
You can call this to change the title, and other Window properties.
ci::app::getWindow()->setTitle("Respoducir Video");
Cinder v0.9.1
The include path has changed to:
#include "cinder/app/Window.h"
