QTableView QValidator.

[cultivation]

Hi,

I am displaying some editable data with a QTableView.
I want to validate some data with a QValidator. This should be possible.
but i cant find the needed functions.

@Qtableview tableView;
tableView.setmodel( ... );

QIntValidator* intValidator(0,11,tableView);

// tableView.setvalidator(column 2, validator intValidator);@

Any help is appreciated, thanks.

what exactly do you want to do?
Validate the existing data of a table or the data the user can edit in the table?

Data input from the user.

Then you'll have to make a "custom item delegate":http://qt-project.org/doc/qt-4.8/qstyleditemdelegate.html setting up the validator when creating the editor

which function creates the editor?
@QWidget * QStyledItemDelegate::createEditor ( QWidget * parent, const QStyleOptionViewItem & option, const QModelIndex & index ) const@

But how will i set the validator to the widget?

@class tableValidator : public QStyledItemDelegate
{
Q_OBJECT
public:
explicit tableValidator(QValidator* validator=0, QObject *parent = 0) : QStyledItemDelegate(parent)
{
Validator = validator;
}

virtual ~tableValidator()
{
    
}

signals:

public slots:

private:
QValidator* Validator;

};@

easiest way would be probably this:
@
QWidget * MyDelegate::createEditor ( QWidget * parent, const QStyleOptionViewItem & option, const QModelIndex & index ) const
{
QWidget* editor = QStyledItemDelegate::createEditor(parent, option, index);
QLineEdit* lineEditEditor = qobject_cast<QLineEdit*>(editor);
if( lineEditEditor )
lineEditEditor->setValidator(myValidator);

 return editor;

}
