[Qt-interest] What widget was clicked?

[Keiver Hdez Fdez]

Hello folks, I have some widget added dynamically, like this: 

QWidget * uno = new QWidget(parent); 
uno->setStyleSheet("background: yellow"); 
QWidget * dos = new QWidget(parent); 
dos->setStyleSheet("background: blue"); 
QWidget * tres = new QWidget(parent); 
tres->setStyleSheet("background: white"); 

ui->horizontalLayout->addWidget(uno); 
ui->horizontalLayout->addWidget(dos); 
ui->horizontalLayout->addWidget(tres); 

How do I know what was the widget the user clicked? Take a look at the picture. 

Thanks in advance. 

Saludos, 
Ing. Keiver Hdez Fdez.
