Re access a label after creating several one with the same name &different objectname

[lipos123]

Hi,

I have a little problem with accessing a label, after creating several labels using the same name.
Each time i create a label, i use the following code:

QLabel* lbl = new QLabel(" ", ui->scrollAreaContents);

The problem is that I don't know how to re access a specified label in order to change the text of the corresponding label.
I tried to set for each "lbl" created an ObjectName, in order to differentiate between all the labels created:

lbl->setObjectName("label" + QString::number(i));

Is the setObjectName() a good way to solve my problem? if so, how should i change the text of a specified label using the ObjectName ?
And if it's not a good solution, how should i solve my problem ?

Any help would be appreciated,

Best Regards,

why dont u use a list of label?!??
try to use like this
i use that for push button

QList<QPushButton*> myPushButtonArray;

for (int n = 1; n <=10; n++)
{
myPushButtonArray[n] = new QPushButton("whatever the name here",this);
}

and u can use sender() function to know which button is pressed for example
as for ex:

connect(myPushButtonArray.at(n), SIGNAL(clicked()),this, SLOT(test()));

void MainWindow::test()
{

if(sender()== myPushButtonArray.at(1))
{
QMessageBox::information(this,"" , "button1");
}

}

hope that will help you

I've tried this solution but it didn't work. The application crash if several labels are created in a very short time.
Any other ideas ?

u can use a QTimer to accomplish this function
this will execute the function when it is ready
i have used it many times and it works great

Thanks Rondo23 for your idea.
I solved using another method. I have created several label using same name but different ObjectName, and to access a specific label using the objectName i have used findChildren method to search for the label that i want to modify.

Thanks,
Best Regards.
