Event textChanged on dynamically created QLineEdit

Question

I have some code in on_pushButton_clicked() that creates another QLineEdit, and I would like to ask you how can I access the on_lineEdit_textChanged() event of that new QLineEdit.

Answer 1

You should use connect method like this:

QLineEdit* le= new QLineEdit(this);
....add to layout.....
connect(le, SIGNAL(textChanged(const QString &)), this, SLOT(on_lineEdit_textChanged(const QString &)));
