【转】Qt中QTableView中加入Check列实现
class MyModel : public QSqlQueryModel {
Q_OBJECT
public:
MyModel(QObject *parent = 0);
Qt::ItemFlags flags(const QModelIndex &index) const;
QVariant data(const QModelIndex &index, int role = Qt::DisplayRole) const;
........
};
Qt::ItemFlags MyModel::flags(const QModelIndex &index) const {
Qt::ItemFlags flags = QSqlQueryModel::flags(index);
if (index.column() == aColWithCheckbox)
flags |= Qt::ItemIsUserCheckable;
else
flags |= Qt::ItemIsEditable;
return flags;
}
QVariant MyModel::data(const QModelIndex &index, int role) const {
QVariant value = QSqlQueryModel::data(index, role);
if (role == Qt::CheckStateRole && index.column() == aColWithCheckbox)
return (QSqlQueryModel::data(index).toInt() != 0) ? Qt::Checked : Qt::Unchecked;
else
return value;
}
