Cout in a loop for QLabel Widgets

[Swati777999]

Hi All,

I want to do something like the following:

int n=10;
QMap <int, QLabel*>Names;
for (int ii=0;ii<n;ii++)

{ Names[ii] = new QLabel("Name" ,ii);
}

Output : Name1
Name2

I know that Names[ii] = new QLabel("Name" ,ii) ; is a wrong syntax , I want to get the result like
cout << "Name" <<ii ;

How can it be achieved in Qt?

Names[ii] = new QLabel(QString("Name %1").arg(ii));

This syntax gives me error.

Of course. Please learn to read documentation (https://doc.qt.io/qt-5/qlabel.html)!
There is no such constructor in QLabel.
What do you actually want to do?
Do you want to show the number (ii) in the label?

@jsulm

I want to show something like this:
Name 1
Name 2
Name 3
etc.

[jsulm]

@Swati777999

Names[ii] = new QLabel(QString("Name %1").arg(ii));

Yes, that's the reason why I've specifically mentioned it in my post. There's no such declaration in label for the output of Name ii. Is there any other way to achieve it?

Works perfectly! Thanks.
