Someone knows what happend with this code:

Qt Code: 
  1. connect(TXTxinf2, SIGNAL(textChanged(QString&)), this, SLOT(TXTValidar_changed(QLineEdit *)));
To copy to clipboard, switch view to plain text mode 

Compile without warning or error, but when i run the program say this (linux Qt-4.3.1):

Object::connect: No such signal QLineEdit::textChanged(QString&)
