    Detailed Description

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

    The model returns data for the following roles:

    RoleTypeDescriptionSublayerRoles
    nameQStringThe sublayer's name.SublayerNameRole
    sublayerVisibleboolWhether the sublayer is enabled to be visible.SublayerVisibleRole
    showInLegendboolWhether the sublayer will be shown in the legend.SublayerShowInLegendRole
    sublayerIdintThe sublayer's ID.SublayerIdRole
    minScaledoubleThe minumum scale at which the sublayer displays.SublayerMinScaleRole
    maxScaledoubleThe maximum scale at which the sublayer displays.SublayerMaxScaleRole
    sublayerTypeArcGISSublayerTypeThe sublayer's type.SublayerTypeRole
    canChangeVisibilityboolWhether the sublayer's visibility can be changed.SublayerCanChangeVisibilityRole
    definitionExpressionQStringThe sublayer's definition expression (since 100.1)SublayerDefinitionExpressionRole
    sublayerOpacityfloatThe sublayer's opacity (since 100.1)SublayerOpacityRole
    scaleSymbolsboolWhether the sublayer renderers its symbols based on scale (since 100.1)SublayerScaleSymbolsRole
    labelsEnabledboolWhether the sublayer's labels are displayed (since 100.1)SublayerLabelsEnabledRole

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

    Signal emitted when an error occurs.

    • error - Details about the error.

    [signal] void ArcGISSublayerListModel::sublayerAdded(int index)

    Signal emitted when a sublayer is added to the list model.

    index is the index of the added sublayer.

    [signal] void ArcGISSublayerListModel::sublayerRemoved(int index)

    Signal emitted when a sublayer is removed from the list model.

    index is the index of the removed sublayer.

    [override virtual] ArcGISSublayerListModel::~ArcGISSublayerListModel()

    Destructor.

    void ArcGISSublayerListModel::append(Esri::ArcGISRuntime::ArcGISSublayer *sublayer)

    Appends a sublayer to the sublayer list model.

    [override virtual] Esri::ArcGISRuntime::ArcGISSublayer *ArcGISSublayerListModel::at(int index) const

    Returns the sublayer at the specified index.

    void ArcGISSublayerListModel::clear()

    Removes all sublayers from the list model.

    bool ArcGISSublayerListModel::contains(Esri::ArcGISRuntime::ArcGISSublayer *sublayer) const

    Returns true if the list model contains the specified sublayer.

    [override virtual] QVariant ArcGISSublayerListModel::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 sublayer 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::ArcGISSublayer *ArcGISSublayerListModel::first() const

    Returns the first sublayer in the list model.

    int ArcGISSublayerListModel::indexOf(Esri::ArcGISRuntime::ArcGISSublayer *sublayer) const

    Returns the index of the sublayer specified.

    void ArcGISSublayerListModel::insert(int index, Esri::ArcGISRuntime::ArcGISSublayer *sublayer)

    Inserts a sublayer 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 ArcGISSublayerListModel::isEmpty() const

    Returns true if the list model contains no sublayers.

    Esri::ArcGISRuntime::ArcGISSublayer *ArcGISSublayerListModel::last() const

    void ArcGISSublayerListModel::removeAt(int index)

    Removes a sublayer at the specified index.

    void ArcGISSublayerListModel::removeOne(Esri::ArcGISRuntime::ArcGISSublayer *sublayer)

    Removes the specified sublayer from the list model.

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

    Returns the number of sublayers contained in the list model.
