    Detailed Description

    Modifying this model (adding, removing, moving) will update the elevation sources available in the Scene.

    The model returns data for the following roles:

    RoleTypeDescriptionElevationSourceRoles
    nameQStringThe elevation source's name.ElevationSourceNameRole
    elevationSourceEnabledboolWhether the elevation source is enabled.ElevationSourceEnabledRole
    elevationSourceTypeElevationSourceTypeThe type of elevation source.ElevationSourceTypeRole

    Member Type Documentation

    enum ElevationSourceListModel::ElevationSourceRoles

    This enum specifies the custom roles which can be used with ElevationSourceListModel::data.

    ConstantValueDescription
    Esri::ArcGISRuntime::ElevationSourceListModel::ElevationSourceNameRoleQt::UserRole + 1The elevation source's name.
    Esri::ArcGISRuntime::ElevationSourceListModel::ElevationSourceEnabledRoleQt::UserRole + 2Whether the elevation source is enabled.
    Esri::ArcGISRuntime::ElevationSourceListModel::ElevationSourceTypeRoleQt::UserRole + 3The type of elevation source.

    Member Function Documentation

    [signal] void ElevationSourceListModel::elevationSourceAdded(int index)

    Signal emitted when an elevation source is added to the list model.

    • index - The index of the added elevation source.

    [signal] void ElevationSourceListModel::elevationSourceRemoved(int index)

    Signal emitted when an elevation source is removed from the list model.

    • index - The index of the removed elevation source.

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

    Signal emitted when an error occurs.

    • error - Details about the error.

    [override virtual] ElevationSourceListModel::~ElevationSourceListModel()

    Destructor.

    void ElevationSourceListModel::append(Esri::ArcGISRuntime::ElevationSource *elevationSource)

    Appends an elevationSource to the elevation source list model.

    [override virtual] Esri::ArcGISRuntime::ElevationSource *ElevationSourceListModel::at(int index) const

    Returns the elevation source at the specified index.

    void ElevationSourceListModel::clear()

    Removes all elevation sources from the list model.

    bool ElevationSourceListModel::contains(Esri::ArcGISRuntime::ElevationSource *elevationSource) const

    Returns true if the list model contains the specified elevationSource.

    [override virtual] QVariant ElevationSourceListModel::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 elevation source 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::ElevationSource *ElevationSourceListModel::first() const

    Returns the first elevation source in the list model.

    int ElevationSourceListModel::indexOf(Esri::ArcGISRuntime::ElevationSource *elevationSource) const

    Returns the index of the elevationSource specified.

    void ElevationSourceListModel::insert(int index, Esri::ArcGISRuntime::ElevationSource *elevationSource)

    Inserts an elevationSource 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 ElevationSourceListModel::isEmpty() const

    Returns true if the list model contains no elevation sources.

    Esri::ArcGISRuntime::ElevationSource *ElevationSourceListModel::last() const

    Returns the last elevation source in the list model.

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

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

    void ElevationSourceListModel::removeAt(int index)

    Removes an elevation source at the specified index.

    void ElevationSourceListModel::removeOne(Esri::ArcGISRuntime::ElevationSource *elevationSource)

    Removes the specified elevationSource from the list model.

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

    Returns the number of elevation sources contained in the list model.
