    Detailed Description

    Modifying this model (adding, removing, moving) will update the SolidStrokeSymbolLayer.

    The model returns data for the following roles:

    RoleTypeDescriptionGeometricEffectRoles
    geometricEffectTypeEsri::ArcGISRuntime::GeometricEffectTypeRolesThe GeometricEffectType enum.GeometricEffectTypeRole

    Member Type Documentation

    enum GeometricEffectListModel::GeometricEffectRoles

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

    Member Function Documentation

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

    Signal emitted when an error occurs.

    • error - Details about the error.

    [signal] void GeometricEffectListModel::geometricEffectRemoved(int index)

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

    index is the index of the removed GeometricEffect.

    [signal] void GeometricEffectListModel::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 GeometricEffectListModel::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] GeometricEffectListModel::~GeometricEffectListModel()

    Destructor.

    void GeometricEffectListModel::append(Esri::ArcGISRuntime::GeometricEffect *geometricEffect)

    Appends a geometricEffect to the geometric effect list model.

    [override virtual] Esri::ArcGISRuntime::GeometricEffect *GeometricEffectListModel::at(int index) const

    Returns the GeometricEffect at the specified index.

    void GeometricEffectListModel::clear()

    Removes all geometric effects 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 GeometricEffectListModel::contains(Esri::ArcGISRuntime::GeometricEffect *geometricEffect) const

    Returns true if the list model contains the specified geometricEffect.

    [override virtual] QVariant GeometricEffectListModel::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 geometric effect 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::GeometricEffect *GeometricEffectListModel::first() const

    Returns the first geometric effect in the list model.

    int GeometricEffectListModel::indexOf(Esri::ArcGISRuntime::GeometricEffect *geometricEffect) const

    Returns the index of the geometricEffect specified.

    void GeometricEffectListModel::insert(int index, Esri::ArcGISRuntime::GeometricEffect *geometricEffect)

    Inserts a geometricEffect 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 GeometricEffectListModel::isEmpty() const

    Returns true if the list model contains no geometric effects.

    Esri::ArcGISRuntime::GeometricEffect *GeometricEffectListModel::last() const

    Returns the last geometric effect in the list model.

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

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

    void GeometricEffectListModel::removeAt(int index)

    Removes a geometric effect 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 GeometricEffectListModel::removeOne(Esri::ArcGISRuntime::GeometricEffect *geometricEffect)

    Removes the specified geometricEffect 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 GeometricEffectListModel::size() const

    Returns the number of geometric effects contained in the list model.
