[Qt-interest] QTreeWidgetItem: setFlags only on some columns

[Malyushytsky, Alex]

I guess it is possible by using setItemDelegateForColumn() or setItemDelegate().

( QAbstractItemDelegate * delegate ).
Override createEditor in your QItemDelegate subclass.

Either prevent all editors to be created
QWidget* MyItemDelegate::createEditor( QWidget *parent,
        const QStyleOptionViewItem &option, const QModelIndex &index) const
{
 return NULL;
}
and  set delegate with setItemDelegateForColumn for columns you don't want to be editable.

Or allow/prevent creation editor in the createEditor depending on column.
This way is a bit more complex, but it will also allow you to customize editors for each column ( for example set validators):

QWidget* MyItemDelegate::createEditor( QWidget *parent,
        const QStyleOptionViewItem &option, const QModelIndex &index) const
{
        Q_ASSERT( tableSource && makeDialog ); // init MUST be called already

        QWidget* w = NULL;

        QTableWidgetItem* item = treeWidgetSource->itemFromIndex ( index );
        if( item )
        {
// where treeWidgetSource - your QTreeWidget
                int column = item->column();

                if( column == 1 )
            {
                        w = QItemDelegate::createEditor( parent, option, index); // set validator if you want here
             }
                else
                  w=NULL;
..................
      }

return w;

}

Code is not tested, written on the fly, but you should be able to make it work.

Hi to all!

Is it possible to set editable only some columns of a QTreeWidgetItem
(that is, setting different flags on different columns?)

Thanks

giacomo
