Hi,
In 4.2 it is as simple as having your data() function from your model to
return a Qt::Alignment flag for the appropriate row/column. I haven't tried
4.3 (yet).

I apologise,
And of course when role == Qt::TextAlignmentRole... I was a little too fast.

Hi Stefan, I didn't get it at first but finally got the solution. I was
interested in a particular column so used the following.
ui.ipTableView->setItemDelegateForColumn ( 2, new column2Delegate(this) );
#include <QItemDelegate>
class column2Delegate : public QItemDelegate
{
Q_OBJECT
public:
column2Delegate::column2Delegate(QObject *parent)
: QItemDelegate(parent)
{
}
void column2Delegate::paint(QPainter *painter,
const QStyleOptionViewItem &option,
const QModelIndex &index) const
{
QDate text = index.model()->data(index, Qt::DisplayRole).toDate();
QStyleOptionViewItem myOption = option;
myOption.displayAlignment = Qt::AlignRight | Qt::AlignVCenter;
drawDisplay(painter, myOption, myOption.rect, text.toString("MM-dd-yyyy"));
drawFocus(painter, myOption, myOption.rect);
}
};
Thanks for the help.

Yes,
but my point was that if you have a custom model, you *should* have a data()
function (the one u call in ur code to get the date) inherited.
In THAT data function u can do:
QVariant
YourCustomModel::data( const QModelIndex &index, int role ) const
{
/* more code */
if ( index.column() == 2 && role == Qt::TextAlignmentRole ) {
return Qt::AlignRight | Qt::AlignVCenter;
}
/* more code */
}
And then you dont need a QItemDelegate subclass of your own ;-)
Although I haven't tested if it works for QDate displays, but i'm assuming it
does.
