Description
Set QListView as QComboBox's view. Add more than maxVisibleItems rows. Use QListView::setRowHidden to hide one row. Popup will show maxVisibleItems - 1 rows despite there are still more than maxVisibleItems rows in model. If you hide maxVisibleItems rows, popup become completely collapsed.
Code sample:
QComboBox comboBox; QListView* view = new QListView; comboBox.setView(view); for (int row = 0; row < comboBox.maxVisibleItems() * 2; ++row) { view->model()->insertRow(view->model()->rowCount(), QModelIndex()); const QModelIndex index = view->model()->index(view->model()->rowCount() - 1, 0, QModelIndex()); view->model()->setData(index, QVariant(QString::number(row)), Qt::DisplayRole); } for (int row = 0; row < comboBox.maxVisibleItems() - 1; ++row) { // Popup become shorter after each iteration view->setRowHidden(row, true); }
