ComboBox Of CheckBoxes not working in Qt5

Fahad Al-Saidi

When I tried this example in Qt5.6 checkboxes doesn’t rendered at all. However, It works fine in Qt4.
Why ? is it a bug or the behaviour changed in Qt 5? Is there any workaround?

Hi,

You can very simple implement by Qt5.
Something like this:

auto    lw = new QListWidget;
foreach (auto str, QStringList() << "a" << "b" << "c") {
    auto    li = new QListWidgetItem(str);

    li->setFlags(li->flags() | Qt::ItemIsUserCheckable);
    li->setCheckState(Qt::Unchecked);
    lw->addItem(li);
}

comboBox->setModel(lw->model());
comboBox->setView(lw);

@Devopia53 Thanks, the checkboxes are displayed at least but selection by mouse is very difficult. I don't know why. UPDATE I comment out li->flags() and things works fine.
