Yeah, I also recall it was working correctly when I used it last time...
However, the example acts "wrongly", but it somehow only happens when the
validator is set. The attached example (w/o the validator) works correctly.

#include <QtGui>
class QUppercaseValidator : public QValidator
{
public:
QUppercaseValidator(QObject *parent) : QValidator(parent) {}
virtual State validate(QString &s, int &) const { fixup(s);
return Acceptable; }
virtual void fixup(QString &s) const { s = s.toUpper(); }
};
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QWidget w;
QLineEdit *edit1 = new QLineEdit;
QLineEdit *edit2 = new QLineEdit;
QLabel *label = new QLabel;
//edit2->setValidator(new QUppercaseValidator(edit2));
QObject::connect(edit1, SIGNAL(textChanged(const QString &)), edit2,
SLOT(setText(const QString &)));
QObject::connect(edit2, SIGNAL(textEdited(const QString &)), label,

w.setLayout(layout);
w.show();
return a.exec();
