You can have an array of pointers to QLabel.

QList<QLabel*> array;

QList<QLabel*> array;

To copy to clipboard, switch view to plain text mode

QList<QLabel *> labels;
for (int i = 0; i < 10; ++i)
   labels << new QLabel(this);
...
for (int i = 0; i < 10; ++i)
   labels.at(i)->setText(QString::number(i));
...

QList<QLabel *> labels;
for (int i = 0; i < 10; ++i)
   labels << new QLabel(this);
...
for (int i = 0; i < 10; ++i)
   labels.at(i)->setText(QString::number(i));
...

I do with a vector like this:

QLabel *lbArr[SIZE];
 
for (int i = 0; i < SIZE; ++i)
   lbArr[i] = new QLabel(this);
 
 
for (int i = 0; i < SIZE; ++i)
   lbArr[i]->setText( tr("Label n. %1").arg(i) );

QLabel *lbArr[SIZE];

for (int i = 0; i < SIZE; ++i)
   lbArr[i] = new QLabel(this);


for (int i = 0; i < SIZE; ++i)
   lbArr[i]->setText( tr("Label n. %1").arg(i) );

If you know how many Label you need and are not too I think is a better idea use a vector instead of a List.

In that case see this http://www.qtcentre.org/forum/p-qlab...ostcount3.html

Get used to QList and the other Qt classes - they are very convenient and you never will have size problems like with arrays in the post above
