## Detailed Description

The QStringListModel class provides a model that supplies strings to views.

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.

## Member Function Documentation

### QStringListModel::QStringListModel ( QObject * parent = 0 )

Constructs a string list model with the given parent.

### QStringListModel::QStringListModel ( const QStringList & strings, QObject * parent = 0 )

Constructs a string list model containing the specified strings with the given parent.

### QVariant QStringListModel::data ( const QModelIndex & index, int role ) const `[virtual]`

Returns data from the item with the given index for the specified role.

If the view requests an invalid index, an invalid variant is returned.

Reimplemented from QAbstractItemModel.

See also setData().

### Qt::ItemFlags QStringListModel::flags ( const QModelIndex & index ) const `[virtual]`

Returns the flags for the item that corresponds to the given index.

Valid items are enabled, selectable, and editable.

Reimplemented from QAbstractItemModel.

### bool QStringListModel::insertRows ( int row, int count, const QModelIndex & parent = QModelIndex() ) `[virtual]`

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.

Reimplemented from QAbstractItemModel.

See also QAbstractItemModel::insertRows().

### bool QStringListModel::removeRows ( int row, int count, const QModelIndex & parent = QModelIndex() ) `[virtual]`

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.

Reimplemented from QAbstractItemModel.

See also QAbstractItemModel::removeRows().

### int QStringListModel::rowCount ( const QModelIndex & parent = QModelIndex() ) const `[virtual]`

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 used in most models to specify the parent of the rows to be counted. In this model, the parent is ignored.

Reimplemented from QAbstractItemModel.

See also insertRows(), removeRows(), and QAbstractItemModel::rowCount().

### bool QStringListModel::setData ( const QModelIndex & index, const QVariant & value, int role = Qt::EditRole ) `[virtual]`

Sets the data for the item corresponding to the given index in the model to the value for the specifed role.

The dataChanged() signal is emitted if the item is changed.

Reimplemented from QAbstractItemModel.

See also data().

### 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.

See also dataChanged().

### QStringList QStringListModel::stringList () const

Returns the string list used by the model to store data.
