LabelDefinitionListModel Class | ArcGIS Maps SDK for Qt

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

Destructor.

void LabelDefinitionListModel::append(Esri::ArcGISRuntime::LabelDefinition *labelDefinition)

Appends a labelDefinition to the LabelDefinition list model.

[override virtual] Esri::ArcGISRuntime::LabelDefinition *LabelDefinitionListModel::at(int index) const

Returns the LabelDefinition at the specified index.

void LabelDefinitionListModel::clear()

Removes all LabelDefinitions 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 LabelDefinitionListModel::contains(Esri::ArcGISRuntime::LabelDefinition *labelDefinition) const

Returns true if the list model contains the specified labelDefinition.

[override virtual] QVariant LabelDefinitionListModel::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 LabelDefinition referred to by the index.

index. The index in the model for which to return data.
role. The role for which to return data.

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

Signal emitted when an error occurs.

error - Details about the error.

Esri::ArcGISRuntime::LabelDefinition *LabelDefinitionListModel::first() const

Returns the first LabelDefinition in the list model.

int LabelDefinitionListModel::indexOf(Esri::ArcGISRuntime::LabelDefinition *labelDefinition) const

Returns the index of the labelDefinition specified.

void LabelDefinitionListModel::insert(int index, Esri::ArcGISRuntime::LabelDefinition *labelDefinition)

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

This method will append to the list if the index is greater than the current size of the list model.

bool LabelDefinitionListModel::isEmpty() const

Returns true if the list model contains no LabelDefinitions.

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

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

index is the index of the added item.

This function was introduced in Esri::ArcGISRuntime 100.15.

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

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

index is the index of the removed item.

This function was introduced in Esri::ArcGISRuntime 100.15.

Esri::ArcGISRuntime::LabelDefinition *LabelDefinitionListModel::last() const

Returns the last LabelDefinition in the list model.

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

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

void LabelDefinitionListModel::removeAt(int index)

Removes a LabelDefinition at the specified index.

void LabelDefinitionListModel::removeOne(Esri::ArcGISRuntime::LabelDefinition *labelDefinition)

Removes the specified labelDefinition from the list model.

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

Returns the number of LabelDefinitions contained in the list model.
