QCombobox with multiple columns

[grantbj74]

This is attempt 2 (still doesn't compile).

Can anyone point me in the right direction? I don't have a clue what im doing.

void SerialNumberProg::columnsTrial(
) {
    QTableWidget *tw;
 
    if( ( tw = new QTableWidget( 0, 2, m_qtapp )) != NULL ) {
 
        QTableWidgetItem *item;
        QAbstractItemModel *model = m_qtapp->AllocateEcoComboBox->model();
 
        tw->setModel( model );// DOESN'T LIKE THIS LINE...
 
        int rowcount = tw->rowCount();
        tw->setRowCount( rowcount + 1 );
 
        item = new QTableWidgetItem( "id" );
        tw->setItem( rowcount, 0, item );
 
        item = new QTableWidgetItem( "date" );
        tw->setItem( rowcount, 1, item ); 
 
        m_qtapp->AllocateEcoComboBox->setView( tw );
        delete( tw );
    }
}

void SerialNumberProg::columnsTrial(
) {
    QTableWidget *tw;

    if( ( tw = new QTableWidget( 0, 2, m_qtapp )) != NULL ) {

        QTableWidgetItem *item;
        QAbstractItemModel *model = m_qtapp->AllocateEcoComboBox->model();
    
        tw->setModel( model );// DOESN'T LIKE THIS LINE...
    
        int rowcount = tw->rowCount();
        tw->setRowCount( rowcount + 1 );

        item = new QTableWidgetItem( "id" );
        tw->setItem( rowcount, 0, item );

        item = new QTableWidgetItem( "date" );
        tw->setItem( rowcount, 1, item ); 

        m_qtapp->AllocateEcoComboBox->setView( tw );
        delete( tw );
    }
}

If anyone is after a similar topic try searching for setView.

I got the following to work with ideas from this forum and a colleague.

I got to make a class for it now.

QStandardItemModel *model = new QStandardItemModel( 3, 2, this );
    for (int i = 0; i < model->rowCount(); ++i) {
        QStandardItem* col0 = new QStandardItem( QString("foo%0").arg(i) );
        QStandardItem* col1 = new QStandardItem( QString("bar%0").arg(i) );
        model->setItem(i, 0, col0);
        model->setItem(i, 1, col1);
    }
 
    QTableView* tableView = new QTableView( this );
    tableView->setModel( model );
    tableView->verticalHeader()->setVisible(false);
    tableView->horizontalHeader()->setVisible(false);
    tableView->setColumnWidth ( 0, 60 );
    tableView->setColumnWidth ( 1, 160 );
    tableView->setHorizontalScrollBarPolicy(Qt::ScrollBarAsNeeded);
    tableView->setSelectionBehavior(QAbstractItemView::SelectRows);
    tableView->setAutoScroll(false);
 
    myComboBox->setModel( model );
    myComboBox->setView( tableView );

QStandardItemModel *model = new QStandardItemModel( 3, 2, this );
    for (int i = 0; i < model->rowCount(); ++i) {
        QStandardItem* col0 = new QStandardItem( QString("foo%0").arg(i) );
        QStandardItem* col1 = new QStandardItem( QString("bar%0").arg(i) );
        model->setItem(i, 0, col0);
        model->setItem(i, 1, col1);
    }

    QTableView* tableView = new QTableView( this );
    tableView->setModel( model );
    tableView->verticalHeader()->setVisible(false);
    tableView->horizontalHeader()->setVisible(false);
    tableView->setColumnWidth ( 0, 60 );
    tableView->setColumnWidth ( 1, 160 );
    tableView->setHorizontalScrollBarPolicy(Qt::ScrollBarAsNeeded);
    tableView->setSelectionBehavior(QAbstractItemView::SelectRows);
    tableView->setAutoScroll(false);

    myComboBox->setModel( model );
    myComboBox->setView( tableView );
