CheckBox inside a QTableView

[voilier92]

Hi,
I try to have a checkBox inside a QtableView. For the moment, I try differents solutions (delegate, ..), but I'am not happy with the result. This is the code, I have for the moment
Column 5 must be a checkBox
class MyItemModel is derivated from QStandardItemModel

bool MyItemModel::setData ( const QModelIndex & index, const QVariant & value, int role)
{
    if (index.column()==5)
    {
        if (role==Qt::CheckStateRole)
            return QStandardItemModel::setData(index,value,role);
        return false;
    }
    else
        return QStandardItemModel::setData(index,value,role);
 
}
QVariant MyItemModel::data ( const QModelIndex & index, int role ) const
{
    if (index.column()==5)
    {
        if (role==Qt::CheckStateRole)
            return QStandardItemModel::data(index,role);
        return QVariant();
    }
    else
        return QStandardItemModel::data(index,role);
}
Qt::ItemFlags MyItemModel::flags( const QModelIndex & index ) const
{
    if (index.column()==5)
        return Qt::ItemIsEnabled|Qt::ItemIsSelectable|Qt::ItemIsUserCheckable;
    return Qt::ItemIsEditable|Qt::ItemIsEnabled|Qt::ItemIsUserCheckable|Qt::ItemIsSelectable;
}
 
When I add a line, I use this call
    setData(model->index(0, 5), Qt::Checked,Qt::CheckStateRole);

bool MyItemModel::setData ( const QModelIndex & index, const QVariant & value, int role)
{
    if (index.column()==5)
    {
        if (role==Qt::CheckStateRole)
            return QStandardItemModel::setData(index,value,role);
        return false;
    }
    else
        return QStandardItemModel::setData(index,value,role);

}
QVariant MyItemModel::data ( const QModelIndex & index, int role ) const
{
    if (index.column()==5)
    {
        if (role==Qt::CheckStateRole)
            return QStandardItemModel::data(index,role);
        return QVariant();
    }
    else
        return QStandardItemModel::data(index,role);
}
Qt::ItemFlags MyItemModel::flags( const QModelIndex & index ) const
{
    if (index.column()==5)
        return Qt::ItemIsEnabled|Qt::ItemIsSelectable|Qt::ItemIsUserCheckable;
    return Qt::ItemIsEditable|Qt::ItemIsEnabled|Qt::ItemIsUserCheckable|Qt::ItemIsSelectable;
}

When I add a line, I use this call
    setData(model->index(0, 5), Qt::Checked,Qt::CheckStateRole);

To copy to clipboard, switch view to plain text mode 

With that, I have a checkbox, but it's not centered and there is a text zone (I can edit it, if I put the flag Qt::ItemIsEditable). I woul like to remove the edit zone and center the check box.
Thank for your help

You have to use custom delegate.

You have to use custom delegate.

Hi,

I have tried using custom delegates and it works fine.

But i have another problem. If sorting is enabled in QTableView and i change the sort order then the delegate disappears i.e. it is not used after the model is sorted.

Can some one suggest a way to enable sorting while using custom delegates.

Another approach which i will be trying is to use the QHeaderView signal to indicate that sorting order has been changed and then call QTableView::sortByColumn


thanks,

Anuj
