Detailed Description▲
QStringListModel is an editable model that can be used for simple cases where you need to display a number of strings in a view widget, such as a QListView or a QComboBox.
The model provides all the standard functions of an editable model, representing the data in the string list as a model with one column and a number of rows equal to the number of items in the list.
Model indexes corresponding to items are obtained with the index() function, and item flags are obtained with flags(). Item data is read with the data() function and written with setData(). The number of rows (and number of items in the string list) can be found with the rowCount() function.
The model can be constructed with an existing string list, or strings can be set later with the setStringList() convenience function. Strings can also be inserted in the usual way with the insertRows() function, and removed with removeRows(). The contents of the string list can be retrieved with the stringList() convenience function.
An example usage of QStringListModel:
QStringListModel *model = new QStringListModel();
QStringList list;
list << "a" << "b" << "c";
model->setStringList(list);See Also▲

Member Function Documentation▲
[explicit] QStringListModel::QStringListModel(QObject *parent = nullptr)▲
Constructs a string list model with the given parent.
[explicit] QStringListModel::QStringListModel(const QStringList &strings, QObject *parent = nullptr)▲
Constructs a string list model containing the specified strings with the given parent.
[override virtual] QVariant QStringListModel::data(const QModelIndex &index, int role = Qt::DisplayRole) const▲
Reimplements: QAbstractItemModel::data(const QModelIndex &index, int role) const.
Returns data for the specified role, from the item with the given index.
If the view requests an invalid index, an invalid variant is returned.

[override virtual] Qt::ItemFlags QStringListModel::flags(const QModelIndex &index) const▲
Reimplements: QAbstractListModel::flags(const QModelIndex &index) const.
Returns the flags for the item with the given index.
Valid items are enabled, selectable, editable, drag enabled and drop enabled.

See also QAbstractItemModel::flags()
[override virtual] bool QStringListModel::insertRows(int row, int count, const QModelIndex &parent = QModelIndex())▲
Reimplements: QAbstractItemModel::insertRows(int row, int count, const QModelIndex &parent).
Inserts count rows into the model, beginning at the given row.
The parent index of the rows is optional and is only used for consistency with QAbstractItemModel. By default, a null index is specified, indicating that the rows are inserted in the top level of the model.

[override virtual] bool QStringListModel::removeRows(int row, int count, const QModelIndex &parent = QModelIndex())▲
Reimplements: QAbstractItemModel::removeRows(int row, int count, const QModelIndex &parent).
Removes count rows from the model, beginning at the given row.
The parent index of the rows is optional and is only used for consistency with QAbstractItemModel. By default, a null index is specified, indicating that the rows are removed in the top level of the model.

See also QAbstractItemModel::removeRows()
[override virtual] int QStringListModel::rowCount(const QModelIndex &parent = QModelIndex()) const▲
Reimplements: QAbstractItemModel::rowCount(const QModelIndex &parent) const.
Returns the number of rows in the model. This value corresponds to the number of items in the model's internal string list.
The optional parent argument is in most models used to specify the parent of the rows to be counted. Because this is a list if a valid parent is specified, the result will always be 0.

[override virtual] bool QStringListModel::setData(const QModelIndex &index, const QVariant &value, int role = Qt::EditRole)▲
Reimplements: QAbstractItemModel::setData(const QModelIndex &index, const QVariant &value, int role).
Sets the data for the specified role in the item with the given index in the model, to the provided value.
The dataChanged() signal is emitted if the item is changed.

void QStringListModel::setStringList(const QStringList &strings)▲
Sets the model's internal string list to strings. The model will notify any attached views that its underlying data has changed.

[override virtual] QModelIndex QStringListModel::sibling(int row, int column, const QModelIndex &idx) const▲
[override virtual] void QStringListModel::sort(int column, Qt::SortOrder order = Qt::AscendingOrder)▲
Reimplements: QAbstractItemModel::sort(int column, Qt::SortOrder order).
QStringList QStringListModel::stringList() const▲
[override virtual] Qt::DropActions QStringListModel::supportedDropActions() const▲
Reimplements: QAbstractItemModel::supportedDropActions() const.
