Detailed Description

\inmodule QtCore

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 \l{QAbstractListModel::index()}{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:

list << "a" << "b" << "c";
model->setStringList(list);

◆ data()

QVariant QStringListModel::data ( const QModelIndex & index,
int role = Qt::DisplayRole ) 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.

◆ insertRows()

bool QStringListModel::insertRows ( int row,
int count,
const QModelIndex & parent = QModelIndex() )
override

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.

Returns true if the insertion was successful.

bool QStringListModel::removeRows ( int row,

override

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.

Returns true if the row removal was successful.

◆ rowCount()

int QStringListModel::rowCount ( const QModelIndex & parent = QModelIndex()) const
overridevirtual

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.
