[SOLVED]Loop for QLabels?

[MrNoway]

hi,
i need to create a custom number of Labels

e.g.

@ for (int i=0; i<10; i++){
QLabel *label_i;
label_i = new QLabel;
}@

I know, this is not working, but just to show what I mean.

Is this somehow possible to do it?

i guess it is done using something like this

@QLabel *label_("%1"), i;@

Ui, a question popped up in my mind.
How good is your knowledge about C/C++?

If it would be good you wouldn't ask such question.

BTW. I don't know your problem, but an array of QLabels could solve your problem.

Do you think something like this?:
@for (int i = 0; i < 10; i++)
{

    QLabel* label = new QLabel(QString("label%1").arg(QString::number(i)));

...
}

i passed the first two semester -_-

alright, I solved it.
I didnt know, you can use an array for everything
e.g.
@QLabel *label[10];@

I thought this simplicity, just shouldnt work

thx anyway

and for renaming i used this, what was actually just copied

@QLabel *label[10];@

@for (int i=0; i< 10; i++){
label[i] = new QLabel;
label[i]->setText(QString("%1").arg(i));
label[i]->show(); //Test purpose
}@

Your idea is typical for someone who programs in general with script languages, like perl,phyton etc.
I think there you can do this approach but not in C++.

Put the QLabel array as an member in your class so that you can access it later if you need it.

And do not forget to initialize the array.

@for(int i=0; i<5; ++i)
mLabelArray[i] = new QLabel;@

You can also use QString::number() instead of QString("%1").arg(i)
