    Public Functions

    MultilayerPolygonSymbol(const QList<Esri::ArcGISRuntime::SymbolLayer *> &symbolLayers, QObject *parent = nullptr)
    virtual ~MultilayerPolygonSymbol() override

    Detailed Description

    This is a polygon symbol with multiple layers. Each layer has its own properties like width, height, and offset, that can be combined to create polygon symbols with special effects (a polygon with a marker in the center, for example). These symbols are rendered with polygon geometry.

    Note: Symbol layers in a multilayer symbol are in reverse order of how they appear in the JSON representation.

    // in this multilayer symbol pseudocode json, the 'symbolLayers' ordered list of symbol
    // layers contains a solid stroke symbol layer followed by a solid fill symbol layer.
    { "symbolLayers": [{"type": "CIMSolidStroke", "color": "black"},{"type": "CIMSolidFill", "color": "red"}],"type": "CIMPolygonSymbol" }
    
    // this is the solid fill symbol layer, the reverse order from the json representation
    auto* symbolLayerIndexZero = multilayerSymbol->symboLayers()->at(0); // red fill in the image below
    
    // this is the solid stroke symbol layer, the reverse order from the json representation
    auto* symbolLayerIndexOne = multilayerSymbol->symboLayers()->at(1); // black outline in the image below

    "MultilayerPolygon symbol"

    Multilayer symbol consisting of two layers.
