QValidator problem

[zgulser]

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.



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.



QWidget* StringDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &,const QModelIndex &) const
{
QDoubleSpinBox *dspin = new QDoubleSpinBox(parent);

dspin->setRange(0, 5.1);
return dspin;
}
