Detailed Description
Vertices represent points in a GeometryEditor::geometry. They display the existing location of the point, and are used in interactive workflows to allow you to select and move those points. For more information about selecting and working with selections, see GeometryEditor.
When a vertex is selected (displayed with a selection halo), a GeometryEditorVertex is returned from GeometryEditor::selectedElement.
Select a vertex programmatically using GeometryEditor::selectVertex(int, int), or move it programmatically using GeometryEditor::moveSelectedElement(const Esri::ArcGISRuntime::Point&).
Use GeometryEditorStyle::vertexSymbol and GeometryEditorStyle::selectedVertexSymbol to change the appearance of the vertex when unselected and selected, or set to nullptr to prevent them from being displayed entirely.
To prevent vertices from being selected interactively while still allowing programmatic selection, set InteractionConfiguration::isAllowVertexSelection to false.
