Can I Choose the label on runtime?

[akrep55tr]

Should I choose the label or other ui object before runtime? Can I choose them on runtime?

What I mean is :

Should I write:

for (int i = 0; i < 5 ; i++)
                {
                    ui->label_0->setText(QString::number(i));
                    ui->label_1->setText(QString::number(i));
                    ui->label_2->setText(QString::number(i));
                    ui->label_3->setText(QString::number(i));
                    ui->label_4->setText(QString::number(i));
 
                }

for (int i = 0; i < 5 ; i++)
                {
                    ui->label_0->setText(QString::number(i));
                    ui->label_1->setText(QString::number(i));
                    ui->label_2->setText(QString::number(i));
                    ui->label_3->setText(QString::number(i));
                    ui->label_4->setText(QString::number(i));

                }

To copy to clipboard, switch view to plain text mode 

But I want to write as:

for (int i = 0; i < 5 ; i++)
                {
                    ui->label_(i)->setText(QString::number(i));
 
                }

for (int i = 0; i < 5 ; i++)
                {
                    ui->label_(i)->setText(QString::number(i));

                }

Is it possible to write in this way?

You can't do it like you wrote it.

But, there are a couple of techniques that do let you do this.

1. Use the name of the object.
2. Create a list of objects.

EDIT:
oops, beat to it by tbscope.

No this is not possible the way you wrote it, as you will find out if you try to compile it.
What you can do is put all your labels in a container:

QVector<QLabel*> vecLabels;
vecLabels.push_back(ui->label_0);
vecLabels.push_back(ui->label_1);
...
for (int i = 0; i < 5 ; i++)
                {
                   vecLabels.at(i)->setText(QString::number(i));
 
                }

QVector<QLabel*> vecLabels;
vecLabels.push_back(ui->label_0);
vecLabels.push_back(ui->label_1);
...
for (int i = 0; i < 5 ; i++)
                {
                   vecLabels.at(i)->setText(QString::number(i));

                }
