Member Function Documentation

◆ pathFromIndex()

QString QFSCompleter::pathFromIndex ( const QModelIndex & index) const
overridevirtual

Returns the path for the given index.

The completer object uses this to obtain the completion text from the underlying model.

The default implementation returns the \l{Qt::EditRole}{edit role} of the item for list models. It returns the absolute file path if the model is a QFileSystemModel.

See also
splitPath()

Reimplemented from QCompleter.

◆ splitPath()

QStringList QFSCompleter::splitPath ( const QString & path) const
overridevirtual

Splits the given path into strings that are used to match at each level in the model().

The default implementation of splitPath() splits a file system path based on QDir::separator() when the sourceModel() is a QFileSystemModel.

When used with list models, the first item in the returned list is used for matching.
