Set column as not editable in QTableWidget

Vidhya

@connect(ui->widget,SIGNAL(cellDoubleClicked(int,int)),this,SLOT(column_check(int,int)));

void Saleorder::column_check(int row,int column)
{
QTableWidgetItem* itemtot=ui->widget->item(row, 9);

if( column == 9 )
{
    if (itemtot && !itemtot->text().isEmpty())
    {
        itemtot->setFlags(Qt::ItemIsSelectable|Qt::ItemIsEnabled);
    }

}

}@

i tried this but the program is crashed.

Any one help me solve the problem.

Is there is any other way to achieve to make the entire column as not editable

Thanks in advance

Have you tried unsetting Qt::ItemIsEditable on the respective cells on row creation (not on click)?

Sam

check "this":http://qt-project.org/forums/viewthread/16254/.

S i tried the same code on row creation also

Sam

Did you get it working ?

Vidhya

no its not working . because at first the item is empty

Vidhya

@
Qt::ItemFlags Saleorder::flags( const QModelIndex &index) const
{
Qt::ItemFlags flags = QSqlTableModel::flags(index);
if (index.column() == 9 )
flags &= ~Qt::ItemIsEditable;
return flags;
}@

i use this but it displays the below error message.
saleorder.cpp:98: error: cannot call member function 'virtual Qt::ItemFlags QSqlTableModel::flags(const QModelIndex&) const' without object

Read the compiler message.
flags is not a static function and thus needs an object to be called from. So this:
@
Qt::ItemFlags flags = QSqlTableModel::flags(index);
@
is not valid code.
If saleorder is derived from QSqlTableModel (which i'd doubt) you can do this:
@
Qt::ItemFlags flags = flags(index);
@
otherwise you need a QSqlTableModel object
@
Qt::ItemFlags flags = someQSqlTableModelObject.flags(index);
//or
Qt::ItemFlags flags = someQSqlTableModelObjectPointer->flags(index);
@
Maybe this will work in your case:
@
Qt::ItemFlags flags = ui->widget->model()->flags(index);

try it :

// Qt::noItemFlags disable all flags , and u can add the flags again ;
@
void Saleorder::column_check(int row,int column)
{
if (!ui->widget->item(row, 9)->text().isEmpty())
{
ui->widget->item(row,9)->setFlags(Qt::NoItemFlags|Qt::ItemIsSelectable|Qt::ItemIsEnabled);
}
}
