Creating table in QcomboBox

[devman]

I would like to create a combobox with several columns and with column headers. I point out that I am new to programming with Qt. a bit like the image below. Thank you for kindly helping me. thank you.

@devman
This looks like a combobox up top and a separate widget, mostly QTableView/QTableWidget plus buttons and scrolling at the bottom. Would that satisfy you? I don't know whether you can do all this in a combobox delegate.

Hi and welcome to devnet,

You have two options:

• set a custom view using QComboBox::setView
• as @JonB wrote, use a custom QStyledItemDelegate

@SGaist Oh, I didn't know about QComboBox::setView(), that looks nicely suited for the popup!

@devman MWE:

#include <QtWidgets>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    QMainWindow w;
    QComboBox *combo = new QComboBox(&w);

    QStandardItemModel model(10, 3);
    model.setHorizontalHeaderLabels({"title", "name", "company"});
    for(int i=0; i< model.rowCount(); ++i){
        for(int j=0; j < model.columnCount(); ++j){
            QStandardItem *it = new QStandardItem(QString("%1 - %2").arg(i).arg(j));
            model.setItem(i, j, it);
        }
    }
    combo->setModel(&model);
    combo->setModelColumn(1);

    QTableView *view = new QTableView;
    combo->setView(view);
    view->setSelectionBehavior(QAbstractItemView::SelectRows);
    view->setFixedWidth(350);

    w.show();

    return a.exec();
}

Thank you all for answering me so quickly, I received to do it with a setView but the columns just take the size of the combobox.or me I would like to display several columns even if the combobox is small.

@devman Have you run my MWE? In that code I have set the width of the QTableView which is larger than the width of the QComboBox: view->setFixedWidth(350);

[devman]

Thank you very much eyllanesc, your code works perfectly
