<![CDATA[How to add the check box with item, and Checkbox should check by the user.]]> auto hwList = new QListView(); class HardwareProxyModel : public QSortFilterProxyModel { // Do some Filtering } auto hwListProxyModel = new HardwareProxyModel; hwListProxyModel->setSourceModel(new QStandardItemModel(0, 0)); hwList->setModel(hwListProxyModel);

I access model

  auto model = hwListProxyModel->sourceModel();

and Add the item in model

 auto count = model->rowCount();
 model->insertRow(count);
 auto index = model->index(count, 0);
 model->setData(index, it->name, Qt::DisplayRole);
 model->setData(index, it->channelAmount, Qt::UserRole);

I can add the Item with check box with help of model->setData(index, Qt::Unchecked, Qt::CheckStateRole);

I wanted to add the Item with check box, and that check box should check by user. In above logic, I can add the check box, but user is not able to do check the item.

What Should I have to do if I want to give access to user for check mark?

I am able to make user Checkable.

class CustomListModel : public QStandardItemModel {
public:
Qt::ItemFlags CustomListModel::flags(const QModelIndex & index) const {
Qt::ItemFlags defaultFlags = QStandardItemModel::flags(index);
if (index.isValid()) {
return defaultFlags | Qt::ItemIsUserCheckable;
}
return defaultFlags;
}

CustomListModel(const int row, const int coloumn) :
	QStandardItemModel(row, coloumn) {

}

};

and modification.
hwListProxyModel->setSourceModel(new CustomListModel (0, 0));

Is It any way for setting flag of the model item, if the model is inherit fromQSortFilterProxyModel?
