selectMidVertex method

void selectMidVertex({
  1. required int partIndex,
  2. required int segmentIndex,
})

Selects the mid-vertex with the specified indices.

Mid-vertices do not exist in the GeometryEditor.geometry. They exist only in the display to serve as a visual cue that new vertices can be inserted between existing vertices. Since they do not exist in the geometry, mid-vertices cannot be programmatically moved or deleted. They can be used to insert a new vertex interactively.

When a mid-vertex is selected, a GeometryEditorMidVertex is returned from GeometryEditor.selectedElement.

Parameters:

  • partIndex — The index of the part in the geometry editor's Multipart geometry that contains the mid-vertex to be selected. Use a value of 0 for non-multipart geometry types - ArcGISPoint and Multipoint.
  • segmentIndex — The index of segment that the mid-vertex to be selected lies on, within the given part of the geometry editor's Multipart geometry, or within the Multipoint geometry. Use a value of 0 for ArcGISPoint geometries.
