QValidator problem

Hi,

myLineEdit->setValidator( new QDoubleValidator(0.0, 512.0, 1, this));

when I do the above, firstly it doesn't to the correct range check ( i.e. it accepts 717) and secondly I can't edit myLineEdit again after I pressed enter.

Any ideas?

Thanks in advance

Old topic, but I have a similar issue. I did a lot of trolling but couldn't find anything.

With mine it allows you to type 9.00

I think your supposed to use QValidate::fixUp(), but I am unsure on how to do this.

Code:

---

QWidget* StringDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &,const QModelIndex &) const
{
    QLineEdit *editor = new QLineEdit(parent);
    QDoubleValidator* val = new QDoubleValidator(editor);
 
    val->setNotation(QDoubleValidator::StandardNotation);            
    val->setRange(0, 5.1, 2);
    editor->setValidator(val);
 
    return editor;
}

Anyone got some tips please?

I stumbled across QDoubleSpinBox, that fixed it for me.

Code:

---

QWidget* StringDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &,const QModelIndex &) const
{
    QDoubleSpinBox *dspin = new QDoubleSpinBox(parent);
 
    dspin->setRange(0, 5.1);
    return dspin;
}
