Qt How to know when a checkbox is selected when created dynamically?

I am trying to dynamically create a checkbox for each restaurant in a vector. I was able to dynamically create checkboxes, but I would then like to know which ones were selected. Here is my code:

for(unsigned int i = 0; i < restaurantList.size(); i++)
{
   QCheckBox *thisCheckBox = new QCheckBox(restaurantList.at(i).GetName());
   CTui->verticalLayout->addWidget(thisCheckBox);
}

I currently have 5 restaurants filled in the vector, and as of now I have it look something like this:

() McDonalds

() Papa John's

() Burger King

() Dominos

() Taco Bell

When they click an "OK" button, I would like to know which ones were selected. They are all called thisCheckBox, so I don't know how to get each specific one. How can I do this? Any help is much appreciated!
