Hi All,
I am having one QFrame in QDialog, I need to create dynamic labels based on some input given by user.the number of label is based on user input.
[ for Ex if user gives 6 as input i need 6 labels and then next if he gives 4 second time i need only 4 ,so i need to remove 2 labels now]
How to achieve this ?

What if you do something like this:
for (int i = 0; i < numberOfLabelsSpecified; i++) {
...
yourLayout->addWidget(new QLabel(........), row, column);
...
}

Now i got Solution ,
I used the folowing code ,
Every time when user gives some input and clicks some button, in button click,
for(int i=0;i<listLabel->count();i++)
{
delete listLabel->at(i);
}
listLabel->clear();
for(int i = 0;i<lineEdit->text().toInt();i++)
{
QLabel* l = new QLabel("Hello"+QString::number(i));
layout->addWidget(l,0,i);
listLabel->append(l);
}
Here listLabel is the QList<QLabel*> ,layout is QGridLayout applied to QFrame. I have the following code in Constructor
setupUi(this);
layout = new QGridLayout(frame);
listLabel = new QList<QLabel*>();
connect(pushButton,SIGNAL(pressed()),this,SLOT(add ()));
Thank you for ur Guidence.
