DisplayFilterListModel Class | ArcGIS Maps SDK for Qt

Member Function Documentation [override virtual noexcept] DisplayFilterListModel::~DisplayFilterListModel()

Destructor.

void DisplayFilterListModel::append(Esri::ArcGISRuntime::DisplayFilter *displayFilter)

Appends the displayFilter to the display filter list model.

[override virtual] Esri::ArcGISRuntime::DisplayFilter *DisplayFilterListModel::at(int index) const

Returns the display filter at the specified index.

void DisplayFilterListModel::clear()

Removes all display filters from the list model.

List models do not take ownership of the objects they contain. Therefore, removing or clearing objects from the list model will not delete those objects. An RAII technique should be used to ensure that memory is properly deallocated.

bool DisplayFilterListModel::contains(Esri::ArcGISRuntime::DisplayFilter *displayFilter) const

Returns true if the provided displayFilter is in the list model.

[override virtual] QVariant DisplayFilterListModel::data(const QModelIndex &index, int role = Qt::DisplayRole) const

Reimplements: QAbstractItemModel::data(const QModelIndex &index, int role) const.

Returns the data stored under the given role for the display filter referred to by the index.

[signal] void DisplayFilterListModel::errorOccurred(const Esri::ArcGISRuntime::Error &error)

Signal emitted when an error occurs.

Esri::ArcGISRuntime::DisplayFilter *DisplayFilterListModel::first() const

Returns the first display filter in the list model.

int DisplayFilterListModel::indexOf(Esri::ArcGISRuntime::DisplayFilter *displayFilter) const

Returns the index of the provided displayFilter in the list model.

void DisplayFilterListModel::insert(int index, Esri::ArcGISRuntime::DisplayFilter *displayFilter)

Inserts a displayFilter at a specified index in the list model.

bool DisplayFilterListModel::isEmpty() const

Returns true if this list model is empty.

[signal, since Esri::ArcGISRuntime 100.15] void DisplayFilterListModel::itemAdded(int index)

Signal emitted when an item is added to the list model.

This function was introduced in Esri::ArcGISRuntime 100.15.

[signal, since Esri::ArcGISRuntime 100.15] void DisplayFilterListModel::itemRemoved(int index)

Signal emitted when an item is removed from the list model.

This function was introduced in Esri::ArcGISRuntime 100.15.

Esri::ArcGISRuntime::DisplayFilter *DisplayFilterListModel::last() const

Returns the last display filter in the list model.

void DisplayFilterListModel::move(int from, int to)

Moves one display filter from an index in the list model to a different index.

void DisplayFilterListModel::removeAt(int index)

Removes a display filter at the specified index in the list model.

List models do not take ownership of the objects they contain. Therefore, removing or clearing objects from the list model will not delete those objects. An RAII technique should be used to ensure that memory is properly deallocated.

void DisplayFilterListModel::removeOne(Esri::ArcGISRuntime::DisplayFilter *displayFilter)

Removes the specified displayFilter from the list model.

List models do not take ownership of the objects they contain. Therefore, removing or clearing objects from the list model will not delete those objects. An RAII technique should be used to ensure that memory is properly deallocated.

[override virtual] int DisplayFilterListModel::size() const

Returns the number of display filters in the model.
