[Qt-interest] QLineEdit - textChanged signal - determine old value

[Colin S. Miller]

Hi,

In the slot handling QLineEdit::textChanged,
is there any way to determine the previous value of the QLineEdit control
prior to the signal being fired?

I tried

     QLineEdit control = dynamic_cast<const QLineEdit*>(sender());
     std::cout << "Old value is: " << control->text() << std::endl;

but the value had already been changed.

TIA,
Colin S. Miller
