QLineEdit automatic money format.

[wirasto]

How to make QLineEdit set display data to money format ? Like, if user type 1000000 then QLineEdit text display autochange to 1.000.000. Of course, the Qlineedit just allow number type. Other character will deny, included . (dot) character.

So far, I use QRegExpValidator for validating user input. And use eventFilter for reject . (dot) character.
But, I don't know how to autochange text display in QLineEdit to money format.

This code who I use.

Dialog::Dialog(QWidget *parent)
    : QDialog(parent), ui(new Ui::Dialog)
{
    ui->setupUi(this);
 
    QRegExp rx("[1-9][\\d*|.]*");
    QValidator *i = new QRegExpValidator(rx, this);
    ui->lineEdit->setValidator(i);
 
    ui->lineEdit->installEventFilter(this);
}
 
Dialog::~Dialog()
{
    delete ui;
}
 
 bool Dialog::eventFilter(QObject *obj, QEvent *event)
 {
     if (obj == ui->lineEdit) {
         if (event->type() == QEvent::KeyPress) {
             QKeyEvent *keyEvent = static_cast<QKeyEvent*>(event);
             if (keyEvent->key()==46) return true;
         }
     }
     // pass the event on to the parent class
    return QDialog::eventFilter(obj, event);
 }

Dialog::Dialog(QWidget *parent)
    : QDialog(parent), ui(new Ui::Dialog)
{
    ui->setupUi(this);

    QRegExp rx("[1-9][\\d*|.]*");
    QValidator *i = new QRegExpValidator(rx, this);
    ui->lineEdit->setValidator(i);

    ui->lineEdit->installEventFilter(this);
}

Dialog::~Dialog()
{
    delete ui;
}

 bool Dialog::eventFilter(QObject *obj, QEvent *event)
 {
     if (obj == ui->lineEdit) {
         if (event->type() == QEvent::KeyPress) {
             QKeyEvent *keyEvent = static_cast<QKeyEvent*>(event);
             if (keyEvent->key()==46) return true;
         }
     }
     // pass the event on to the parent class
    return QDialog::eventFilter(obj, event);
 }

The regexp is wrong. It says "a non-zero digit followed by any number of digits or any other characters". I doubt that's what you wanted.
