    Detailed Description

    Modifying this model (adding, removing, moving) results in updates to any objects that are currently referencing these subtype sublayers.

    The model returns data for the following roles:

    RoleTypeDescriptionSubtypeSublayerRoles
    nameQStringThe subtypeSublayer's name.SublayerNameRole
    sublayerVisibleboolWhether the subtypeSublayer is enabled to be visible.SublayerVisibleRole
    showInLegendboolWhether the subtypeSublayer will be shown in the legend.SublayerShowInLegendRole
    sublayerIdintThe subtypeSublayer's ID.SublayerIdRole
    minScaledoubleThe minumum scale at which the subtypeSublayer displays.SublayerMinScaleRole
    maxScaledoubleThe maximum scale at which the subtypeSublayer displays.SublayerMaxScaleRole
    sublayerTypeArcGISSublayerTypeThe subtypeSublayer's type.SublayerTypeRole

    Member Function Documentation

    [signal] void SubtypeSublayerListModel::errorOccurred(Esri::ArcGISRuntime::Error error)

    Signal emitted when an error occurs.

    • error - Details about the error.

    [signal] void SubtypeSublayerListModel::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] void SubtypeSublayerListModel::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.

    [override virtual] SubtypeSublayerListModel::~SubtypeSublayerListModel()

    Destructor.

    void SubtypeSublayerListModel::append(Esri::ArcGISRuntime::SubtypeSublayer *subtypeSublayer)

    Appends a subtypeSublayer to the subtypeSublayer list model.

    [override virtual] Esri::ArcGISRuntime::SubtypeSublayer *SubtypeSublayerListModel::at(int index) const

    Returns the subtypeSublayer at the specified index.

    void SubtypeSublayerListModel::clear()

    Removes all sublayers 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 SubtypeSublayerListModel::contains(Esri::ArcGISRuntime::SubtypeSublayer *subtypeSublayer) const

    Returns true if the list model contains the specified subtypeSublayer.

    [override virtual] QVariant SubtypeSublayerListModel::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 subtypeSublayer referred to by the index.

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

    Esri::ArcGISRuntime::SubtypeSublayer *SubtypeSublayerListModel::first() const

    Returns the first subtypeSublayer in the list model.

    int SubtypeSublayerListModel::indexOf(Esri::ArcGISRuntime::SubtypeSublayer *subtypeSublayer) const

    Returns the index of the subtypeSublayer specified.

    void SubtypeSublayerListModel::insert(int index, Esri::ArcGISRuntime::SubtypeSublayer *subtypeSublayer)

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

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

    bool SubtypeSublayerListModel::isEmpty() const

    Returns true if the list model contains no sublayers.

    Esri::ArcGISRuntime::SubtypeSublayer *SubtypeSublayerListModel::last() const

    Returns the last subtypeSublayer in the list model.

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

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

    void SubtypeSublayerListModel::removeAt(int index)

    Removes a subtypeSublayer at the specified index.

    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 SubtypeSublayerListModel::removeOne(Esri::ArcGISRuntime::SubtypeSublayer *subtypeSublayer)

    Removes the specified subtypeSublayer 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 SubtypeSublayerListModel::size() const

    Returns the number of sublayers contained in the list model.
