How to keep track of QLabel created in a loop using new operator

Question

I am creating many labels based inside a loop using new operator in Qt, something like this:

QLabel *p;
for(int i=0; i<10; i++)
    {
    p = new QLabel(this);
    // ...
    }

Now what is happening, when I am using p it points to the last label in the sequence but I want to use my first label. How can I keep track of every label?

Answer 1

You could store all Label-pointer using std::vector :

std::vector<QLabel*> labels;

for (int i=0; i<10; i++)
   labels.push_back(new QLabel(this));

Accessing these pointers can be done array-like:

QLabel *first = labels[0];

Or by using iterators:

std::vector<QLabel*>::iterator itr = labels.begin();
QLabel *first = *itr;
