QValidatoe

hi ,
i have a qlineedit which should accept only numbers and nothing else.I wrote the below code.This only allows me to enter a digit of length 10.But i should be able to enter a text of any length.Wts the prob with my code?

QValidator *validator = new QIntValidator(this);
m_ctrllineedit->setValidator(validator);

try to set a regular expression in the validator costructor

QRegExp regExp ( "initialize it with your expression" );
m_ctrllineedit->setValidator ( new QRegExpValidator ( regExp , this ) );

QRegExp regExp ( "initialize it with your expression" );
m_ctrllineedit->setValidator ( new QRegExpValidator ( regExp , this ) );

To copy to clipboard, switch view to plain text mode
